Quick Start
Before using the ASEK, Allegro recommends that you read and understand this entire document.
However, in most cases, basic configuration can be done very quickly so that you can start to
familiarize yourself with the ASEK. The basic steps are described in this section. The configura-
tions described are for operating the ASEK in a direct connection to a personal computer that has
an Internet Web browser installed.
To set up the ASEK, perform the following steps:
1Connect the ASEK Main Board module to the computer using either a standard Ethernet
crossover cable, or a separately-powered Ethernet hub and two standard Ethernet LAN cables
(the computer may be powered-on at any time).

Allegro® Sensor Evaluation Kit Technical Guide | ASEK2-UG 1 - 1
Chapter 1
Introduction
Welcome to the Allegro Sensor Evaluation Kit (ASEK). The ASEK boards, together with the Web-
based firmware application, provide a powerful and flexible system for evaluation and program-
ming of Allegro Hall-effect sensors. The kit includes a calibration board that provides a rapid and
repeatable method for calibrating the ASEK Main Board.
Applications
The ASEK system is intended for use with field-programmable Hall effect devices offered by sale
by Allegro. This includes the following types of devices:
• 2-, or 3- or 4-wire switches or latches that are programmed using the supply pin
• 3-wire linear sensors that are programmed using the output pin
The firmware for the kit includes configuration data for specific Allegro devices that are supported
at the time of release of the kit. From time to time, as additional devices become available, the
firmware may be updated to adapt to those devices, and made available in updated versions of
this kit. Contact your local Allegro field applications engineering office for details on supported
devices.
The kit is intended for use as:
• a benchtop engineering tool for evaluating individual Allegro sensor devices; it can be used to
characterize and understand the performance of the various types of sensor devices
• calibrating field-programmable Allegro devices in small volumes; the device is ideal for charac-
terizing the effects of the various register value increments and for understanding and develop-
ing procedures for programming code streams for use on production systems
Additional device development kits for other Allegro devices may be available on the Allegro web-
site, www.allegromicro.com, by following the On-line Store link.
ASEK Software
The programs required to access and operate the ASEK are pre-installed as firmware on the Main
Board of the ASEK. The firmware falls into the following categories:
• Main Application. One graphical interface provides access to all functions, and it opens auto-
matically upon accessing the IP address of the ASEK Main Board. These functions are sum-
marized in the following items.
CAUTION: The ASEK system is intended for low-volume engineering applications. It is not
intended to be used in volume production environments, other than for system
development purposes.

modes (the 137x family).
• Desktop Utility. This module allows the operator to perform hands-on benchtop and in situ sys-
tem evaluations of the behavior of various Allegro field-programmable devices. It includes:
– Desktop Utility. This module provides an interface to sending and receiving data
from the ASEK.
– 136X Utility. This module provides a specific interface for working with linear
devices in the A136x family.
– Configuration File. This contains information about particular devices, used with
the Desktop and 136X utilities.
ASEK Hardware
The kit hardware consists of a module housing the main controller and system interface printed cir-
cuit board (PCB) assembly, with peripheral PCB assemblies that serve as interfaces for mounting
or connecting to DUT sockets. Interconnect cables and a multiregional power supply are also pro-
vided. The general layout of the ASEK system is shown in Figure 1-1 on page 1-3.
Allegro Kit Contents
Before opening the ASEK package, ensure that the necessary support items are available, as
described in System Requirements, on page 1-6. At the minimum, an ESD-resistant pad should be
available for placing the contents as they are unpacked.
The ASEK Board kit comprises several circuit board assemblies, with supporting elements, identi-
fied in Table 1-1.
When the package is received, immediately compare its contents to Table 1-1. If there are any
missing or damaged items, contact your local Allegro field applications engineering office immedi-
ately.

Introduction | System Requirements
1 - 6 ASEK2-UG | Allegro® Sensor Evaluation Kit Technical Guide
System Requirements
This kit includes hardware and software, and requires additional user-supplied equipment to oper-
ate properly.
Network Connections
The ASEK must be operated by a computer, but it is designed to allow the computer to be located
either at the test bench using a direct wired connection, or to be located remotely, connected by
Ethernet LAN. The ASEK includes an Ethernet port.
Although operation of the ASEK for device demonstrations can be performed either locally or via
LAN, changing of the IP address of the ASEK must be performed via direct connection (see
Changing the IP Address, on page 2-2).
For direct connection to the operator computer, the following alternatives can be used:
• A CAT5e 0.9 m Ethernet crossover cable between the ASEK and the operator computer.
• Ethernet standard LAN cable connected to a local separately-powered Ethernet hub, with a
second Ethernet cable connecting from the hub to the operator computer.
• For computers that do not have an Ethernet interface, either type of cable can be connected to
the computer by means of a wired USB Ethernet adapter.
• Wireless, serial port, and parallel port protocols are not supported.
Work Area
The work area should allow the printed circuit board assemblies, as well as the DUT (device under
test) to be protected from ESD (electrostatic discharge) at all times. Standard temperature and
humidity levels should be maintained to suppress ESD.
The boards should be placed on a level work surface, free of objects and obstructions. The sur-
face should be located at an ergonomic height.
The work area should allow the printed circuit board assemblies to be located as near as practica-
ble to each other. For data and power connections between the ASEK Main Board and the periph-
eral PCBs, the ASEK includes a ribbon cable that is approximately 10 cm in length. It is
recommended that the supplied cable always be used as the interface to the peripheral PCBs, and
for best results, it should not be extended in length.

Off-Board Connection
For connection from an ASEK interface PCB to a user-provided DUT
socket that is mounted off-board, connection to on-board Molex 6373
series 6-pin solid header (such as Molex 6471 series Crimp Terminal
Housing 22-01-2025, accepts Molex 4809 series Crimp Terminals 22-30
AWG, such as 85-50111), shielded cable with 4 to 8 conductors and length
as short as possible.
For direct connection from ASEK Main Board to a user-provided DUT
socket (without ASEK interface board), connection to on-board Molex
87833-1420 14-pin ribbon cable PCB header, 2 mm centers (such as
Molex 87568-1494 IDT cable-to-board receptacle).
Ethernet Crossover Cable
Used for IP address setting. 0.9 m or shorter, male RJ45 connectors both
ends; CAT5e crossover cable; compatible with Ethernet 10/100Base-T.
Soldering Equipment DUT sockets acquired from Azimuth Electronics are manually soldered onto the peripheral PCBs. Additional filter components may be required to
be soldered to the PCBs for certain applications.
DUT bypass capacitor As required by application, see DUT datasheet for rating. Recommended maximum rating of 0.1 µF to avoid creating instability in
ASEK system, and minimum 50 V.

Introduction | Safety
Allegro® Sensor Evaluation Kit Technical Guide | ASEK2-UG 1 - 9
Safety
In order to prevent damage to the operator or to the kit or DUT, only qualified electronics techni-
cians or individuals with equivalent training should operate the product.
Follow the safety precautions required by local laws and regulations, and by the procedures of
your company.
The following specific warnings are not meant to be exclusive, or to limit the application of normal
safety precautions in any way:
DUT blowing capacitor
As required by application, see DUT datasheet for rating. Capacitor must
be capable of withstanding higher voltages required for blowing solid state
fuses internal to the DUTs while programming them.
This capacitor may be required to be inserted and removed at different
stages of programming, and a socket should be used. On the ASEK linear
DUT interface PCB, an optional socket is installed with 2.54 mm and 5.08
mm pitch holes, accepts capacitor leads 0.38 mm to 0.64 mm in diameter
and 2.54 mm to 3.71 mm in length (Aries series 0513 collet socket).
CAUTION: Only use the power supply provided with the ASEK. Do not substitute any
other power supply, or damage to the ASEK electronics may occur.
CAUTION: Always take precautions to avoid ESD before handling boards. This includes:
using ESD resistant clothing and gloves, and personal conductive straps, properly
connected to an earth ground. The work surface should be on an ESD-resistant pad, and
the operator should be standing or sitting on an ESD-resistant mat.
