1Product Overview
1.1 Introduction
Measuring only 60mm by 27mm, the MINI8600B processor card is a small
form-factor controller board based on TI’s Sitara AM3359 ARM Cortex-A8
processor. The tiny module integrates 2x256MB of DDR3 SDRAM and 512MB
of NAND Flash and uses two 0.4mm space 2x40-pin board-to-board male
expansion connectors to bring out many hardware peripheral signals and
GPIOs from the CPU.
Embest has designed a single board computer SBC8600B which has an
expansion board to carry the Mini8600B. The flexible design allows the fast
and easy way of realizing and upgrading the controller’s capabilities. In
addition to those features offered by Mini8600B, the SBC8600B features 5
serial ports (including 2 RS232 and 3 TTL), 2 USB Host and 1 USB OTG, 2
Ethernet ports, CAN, RS485, LCD, Touch screen, Audio, ADC and many
other peripherals. The SBC8600B is a ready-to-run platform with support for
Linux 3.2.0, Android 2.3 and WinCE 7 operating systems.

3Hardware Details
3.1 Introduction to CPU
The AM335x microprocessors, based on the ARM Cortex-A8, are enhanced
with image and graphics processing, peripherals, and industrial interface
options such as EtherCAT and PROFIBUS. The device has support for
high-level operating systems such as Linux, WinCE and Android.
The AM335x microprocessor contains these subsystems:
Microprocessor unit (MPU) subsystem based on the ARM Cortex-A8
microprocessor.
POWERVR SGX™ Graphics Accelerator subsystem for 3D graphics
acceleration to support display and gaming effects.
The Programmable Real-Time Unit and Industrial Communication
Subsystem (PRU-ICSS) is separate from the ARM core, allowing
independent operation and clocking for greater efficiency and
flexibility.
3.2 CPU Features
3.2.1 Clock
The AM3359 has two clock inputs, OSC1 and OCC0, and two clock outputs,
LCKOUT1 and LCKOUT2.
OSC1 provides RTC with a 32.768KHz reference clock. And it is used to
connect RTC_XTALIN terminal to RTC_XTALOUT terminal.
OSC0 provides reference clocks such as 19.2-MHz, 24-MHz, 25-MHz or
26-MHz for the clocks without RT function. It is also used to connect the
XTALIN terminal and the XTALOUT terminal.
3.2.2 Reset
Resetting is controlled by PWRONRSTn signals from the CPU. The device is
reset when there is a low level signal.

Page | 9
3.2.3 General-Purpose Interfaces
There are 4 GPIO banks, each of which has 32 I/O pins, giving a total pin
number of 128 (4x32).
3.2.4 Programmable Real-Time Unit Subsystem
The PRUSS of AM3359 consists of 2 programmable real-time units; a 12KB
shared RAM with single-error detection (parity), tree 120B register bank
that can be accessed by each PRU, an interrupt controller module used to
process input events of the system, and the following peripherals:
UART with data flow control and maximum rate of 12Mbps
Two MII Ethernet interfaces with support for industrial Ethernet such
as EtherCAT™
A MDIO interface
An enhanced capture module (eCAP)
3.2.5 3D Graphics Engine
The POWERVR SGX graphics acceleration subsystem is used to improve 3D
image processing, as well as to provide regular display and gaming effects.
The subsystem features:
Tile-Based Architecture Delivering Up to 20 MPloy/sec
Universal Scalable Multi-Threaded Shader Engine Incorporating Pixel
and Vertex Shader Functionality
Advanced Shader Feature Set in Excess of Microsoft VS3.0, PS3.0 and
OGL2.0
Industry Standard API Support of Direct3D Mobile, OGL-ES 1.1 and
2.0, OpenVG 1.0, and OpenMax
3.3 Introduction to Peripherals

If you need more information about the NAND Flash, please refer to
H27U4G8F2DTR-BC.pdf under Disk-SBC8600B\HW design\datasheet\
NAND Flash\
3.3.2 DDR H5TQ2G83CFR-H9C
The H5TQ2G83DFR-H9C is a 256MB DDR3 SDRAM used on SBC8600B.
There are two H5TQ2G83DFR-H9Cs on SBC8600B.
If you need to know more about the SDRAM, please refer to
H5TQ2G83DFR.pdf under Disk-SBC8600B\HW design\datasheet\DDR\.
3.3.3 Ethernet AR8035
AR8035 is a low-power and low-cost Ethernet PHY used on SBC8600B and
integrated with a 10/100/1000Mb transceiver. It is a single-port tri-speed
Ethernet PHY and supports MAC.TM RGMII interfaces.
AR8035 is compliant with the IEEE 802.3az Energy Efficiency Ethernet
Standard and the Atheros’s proprietary SmartEEE standard, which allows
traditional MAC/SoC devices incompatible with 802.3az to function as a
complete 802.3az system.
SBC8600B can be connected to a hub with a straight-though network cable,
or connected to a computer with a crossover cable.
If you need know more about the Ethernet chip, please refer to AR8035.pdf
under Disk-SBC8600B\HW design\datasheet\LAN\.
3.3.4 MAX3232
MAX3232 is used to convert TTL levels into RS232 levels so that the board
can communicate with the RS232 interfaces of PCs.
SBC8600B uses UART0 as a debugging serial interface. The default voltage
of UART0 is 1.8V, which needs to be boosted up to 3.3V for use with RS232.
If you need to know more about this chip, please refer to MAX3232CSE.pdf
under Disk-SBC8600B\HW design\datasheet\ Serial\.
