Chapter 2 Hardware System
2.1 CPU
2.1.1 Introduction to CPU
The AM335x is ARM Cortex-A8 based microprocessor, enhanced in the aspect of
image, graphics processing, peripherals and industrial interface options such as Ether
CAT and PROFIBUS; The device supports high-level operating systems (HLOSs) such as
Linux, WinCE and Android.
The AM335x microprocessor contains following 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.
2.1.2 CPU Features
Clock
AM335x has two clock inputs, OSC1 and OCC0, and two clock outputs, LCKOUT1
and LCKOUT2.
OSC1 provides RTC with a 32.768 KHz reference clock. And it is used to connect
RTC_XTALIN terminal to RTC_XTALOUT terminal.

Embest Technology Co., Ltd 10
Copyright © 2017 Embest Technology SBC8600B-UM-V2.0
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 XTALIN terminal and XTALOUT
terminal.
Reset
Reset is controlled by PWRONRSTn signals from CPU. The reset will be effective
when active low.
General-Purpose Interfaces
There are 4 GPIO banks, each of which has 32 I/O pins, and the total pin number of
GPIO can be 128 (4x32).
Programmable Real-Time Unit Subsystem
Note:
Not applicable to SBC8610B
The PRUSS of AM3358 consists of two 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:
