CHAPTER 1
GENERAL INFORMATION
This chapter contains a general description of the iUP-200A/201A uni ersal
programmer, an o er iew of firmware de elopment, and a description of system
configurations.
Overview f the Universal Pr gramer
The Intel uni ersal programmer programs and erifies Intel programmable read
only memory (PROM) components and other Intel integrated circuits that contain
PROMs. It can be used to program non-erasable bi-polar PROMs, erasable
PROMs (EPROMs), and electrically erasable PROMs (E2PROMs). It can also
read ROM (read only memory) in certain ROM-based components.
The two models of the uni ersal programmer are: the iUP-200A uni ersal
programmer, which operates on-line as a peripheral of an Intel Intellec® micropro
cessor de elopment system, and the iUP-201A uni ersal programmer, which can
be operated either on-line or off-line.
The uni ersal programmer programs the arious PROM de ices using personality
modules. Personality modules are small units that plug into the front of the uni er
sal programmer. They personalize the uni ersal programmer for a specific PROM
or family of PROM de ices. Figure 1-1 shows the iUP-200A uni ersal programmer
with a personality module.
In on-line mode, the Intel PROM programming software (iPPS) controls the uni
ersal programmer. The iPPS software is a utility that runs under the ISIS operat
ing system. It controls the operation of the uni ersal programmer through a serial
I/O port on the de elopment system. The iPPS software pro ides a comprehensi e
set of commands that allow the following operations:
• Reading and writing data to and from disk files.
• Manipulating data in the Intellec memory buffer.
• Mapping data for a particular PROM word size.
• Interlea ing data for different addressing schemes.
• Programming a PROM de ice.
• Reading the contents of the PROM de ice.
• Verifying the contents of the PROM de ice.
• Locking selected PROMs from user access.
The iPPS PROM Programming Software User's Guide describes on-line operation
and the Intel PROM programming software.
You can use the iUP-201A uni ersal programmer as a stand-alone programming
system in off-line mode. You can perform four types of off-line operations as
follows:
• Duplicating and erifying PROMs.

• Locking selected PROMs from user access.
• Down-loading data from any host system that has an RS-232 interface and
programming a PROM with that data.
• Displaying and editing data in local random access memory (RAM).
These off-line operations are performed independently of any host computer
system. (Chapters 3 and 4 describe off-line operation.)
You can expand an iUP-200A uni ersal programmer to iUP-201A uni ersal pro
grammer capability by installing the off-line option. You can install this option
yourself. The off-line option consists of the following:
• A keyboard with a numeric (hex) keypad and arious function keys.
• An alphanumeric display.
• A circuit board that contains control circuitry and 32K bytes of local RAM.
Throughout this manual, the local RAM is referred to as URAM (for user
RAM).
General Descripti n
1-2
The uni ersal programmer is an intelligent peripheral for an Intellec de elopment
system. The uni ersal programmer is connected to a host computer by a two-way
serial interface. (Refer to the Compatible On-Line Hosts section in Chapter 2 for

iUP-200A/201A General Information
further information on connecting the uni ersal programmer to a host.) A dedicat
ed Intel 8085 microprocessor with its own RAM and firmware allows the uni ersal
programmer to perform many operations independently of the host.
The uni ersal programmer is housed in a low-profile case with an angled front
panel. The ON/OFF switch is located on the back panel, and a POWER ON indica
tor light is located on the front panel.
Air con ection through ents at the rear, top, and bottom of the case cool the unit.
The left side of the front panel can hold a personality module. Figure 1-1 shows
the basic iUP-200A uni ersal programmer with an uninstalled personality module.
The iUP-201A uni ersal programmer is identical to the iUP-200A uni ersal pro
grammer except that it has the off-line option installed. Figure 1-2 shows an
iUP-201 A uni ersal programmer with a personality module installed.
The hand-sized personality modules plug into the uni ersal programmer. Each
personality module has one or more de ice sockets which hold PROMs for
programming. LEDs on the personality module indicate the PROM type selected
and the socket to use.
The off-line option of the iUP-201 A uni ersal programmer occupies the right half
of the front panel and consists of an alphanumeric display and a keyboard.
The alphanumeric display has labeled fields for command, address, and data. The
keyboard section contains a numeric (hex) keypad and function keys. The off-line
option also adds 32K of user-accessible RAM (URAM).
The back panel of the uni ersal programmer (shown in Figure 1-3) is the same for
both the iUP-200A uni ersal programmer and the iUP-201A uni ersal
programmer. The main power switch is a rocker switch located in the upper left

Firmware Devel pment
Microprocessors and microcomputers are central elements in designing electronic
products. The typical de elopment process for microprocessor- and
microcomputer-based systems in ol es integrating hardware and software. Once
the software is perfected, it is often installed permanently in a read only memory
(ROM) de ice. Software installed in ROM is referred to as firmware. Firmware is
used in systems design because of its relati e low cost, high speed, and data non
olatility. Non- olatility means that firmware is retained e en when system power
is turned off.
Intel manufactures a wide ariety of ROM memory components which can be
di ided into two general types: masked ROMs and electrically programmable
ROMs (PROMs).
Intel fabricates firmware into a masked ROM during manufacturing. This is often
the most cost effecti e method for including firmware in a mass-produced product.
Programs and data are electrically programmed into a PROM. To electrically pro
gram a PROM, data is presented to a particular address. Voltage is then applied to
programming pins to set (burn in) the code in the selected cell.
Bipolar PROMs can be electrically programmed only once; thereafter, they retain
their data permanently. The programs or data programmed into an EPROM can be
erased by exposing the de ice to ultra iolet light. An E2PROM can be electrically
erased in a manner similar to that used to program it.
EPROMs and E2PROMs allow flexibility during firmware de elopment because
they can be erased and reprogrammed. Some microcomputer components, such as
the Intel 8751, ha e built-in EPROMs in addition to other logic.
For design con enience, some microcomputer components ha e pin-compatible
counterparts containing masked ROM instead of EPROM. This allows the re
programmable EPROM ersion to be used during prototype de elopment and the
masked ROM ersion to be used for the final mass production.
PROM Pr gramming Overview
All PROMs ha e a characteristic physical word length. This word length is the
number of parallel bits that are accessed when a gi en address is specified. Almost
all of Intel’s recent PROM components ha e an 8-bit word; howe er, many earlier
PROMs had 4-bit words.
The difference between a PROM’s physical word length and the logical word
length used in a system must be considered when programming the PROM. For
example, two 8-bit PROM de ices must be connected in parallel to pro ide the 16-
bit-wide memory word that the 8086 microprocessor requires. To put an 8086 ma
chine language program (consisting of a series of 16-bit words) into 8-bit PROM
de ices, the machine code must be formatted so that the 16-bit words are mapped
correctly into each pair of 8-bit de ices. For example, the first PROM might be
programmed with the upper eight bits of each machine code word, while the
second PROM might be programmed with the lower eight bits of each machine
code word.

General Information iUP-200A/201A
The iPPS software pro ides the software tools to perform automatic interlea e
mapping of data and machine code into Intel PROMs. (The iPPS PROM Program
ming Software User's Guide describes iPPS operation.)
System C nfigurati ns
To program PROMs with the iUP-200A/201A uni ersal programmer in on-line
mode, the iPPS software must be running on the Intellec de elopment system. In
addition, the uni ersal programmer must be powered on and connected to the In
tellec de elopment system through an RS-232 configured cable. If you are using
the iUP-201A model, you must select on-line mode with the ON LINE switch
(refer to Chapter 3).
Figure 1-4 illustrates the system data flow in on-line mode. The four major system
de ices (PROM, buffer, file, and URAM) are shown with arrows indicating the di
rections of data flow between these de ices.
The host de elopment system contains the buffer and file de ices, while the uni
ersal programmer contains the PROM and URAM de ices. The URAM de ice is
only a ailable in the iUP-201 A uni ersal programmer. The PROM de ice is
shown as part of a personality module.
The PROM de ice is the PROM component that is plugged into a socket on the
personality module.
The buffer de ice pro ides a temporary area where the iPPS software stores and
manipulates data.
The file de ice is an ISIS file that contains programs or data.
