CHAPTER 4: THE AM3352 PROCESSOR
4. Introduction to the chapter
In this chapter is located the information about the heart of AM3352 – its main processor. The
information is a modified version of the datasheet provided by its manufacturers – Texas
Instruments.
4.1 The processor
The main feature of the AM3352 is the quality manufacturing, the computing power and the very
goo documentation. The software support for the features in the processor is at pretty good state
thanks to the efforts of the BeagleBone community (the most popular board with AM335x
processors) and Texas Instruments themselves.
The exact processor that we use is AM3352ZCZD72. When browsing the documentation of the
processor refer to the information for the ZCZ ball layout.
Of particular importance is that Texas Instruments provides excellent documentation and support
for AM3352.
A short list of features might be found below:
CPU: ARM Cortex-A8 @ 1000 MHz; On-chip L1 cache 64 KB; On-chip L2 cache 256 KB

2×USB ports
3×MMC interfaces
6×UART
3×I2C
3×Enhanced high-resolution PWM modules
ADC×8-channel 12-bit
2×CAN
RTC
General-purpose memories supported: 16-bit (GPMC, NAND flash, NOR flash, SRAM)
DRAM supported: 16-bit (LPDDR-400, DDR2-532,DDR3-800)
More information about the features of the microprocessor can be found in its documentation
available at the web site of its manufactuerer – Texas Instruments:
