AM3352BZCZD80

Overview

The AM3352BZCZD80 is a microprocessor from the Texas Instruments Sitara family, featuring an ARM Cortex-A8 core. It operates at a maximum clock frequency of 800 MHz with a 32-bit data bus width. The device utilizes a PBGA-324 package and supports surface mount installation. Key memory specifications include 32 kB L1 instruction cache, 32 kB L1 data cache, 256 kB L2 cache, 176 kB boot ROM, and 64 kB dedicated RAM. It functions within a temperature range of -40°C to +125°C and requires a 1.26 V operating voltage.

Feature Summary

• Integrates a single-core ARM Cortex-A8 processor for high-performance computing tasks.
• Includes PowerVR SGX graphics accelerator for 3D acceleration and display support.
• Features PRU-ICSS for independent real-time control and industrial communication protocols.
• Supports multiple external memory interfaces including DDR3L and LPDDR.

Applications

• Industrial automation controllers
• Medical devices requiring extended temperature ranges
• Human-machine interface (HMI) displays
• Embedded systems supporting Linux or RTOS

Procurement Notes

Verify the specific suffix D80 corresponds to the 800 MHz speed grade and industrial temperature range (-40°C to +125°C). Confirm package type is PBGA-324. Check RoHS compliance status and moisture sensitivity level before ordering. Ensure supply chain sources provide original manufacturer documentation.

Selection Notes

Select this component when an ARM Cortex-A8 MPU is required with industrial-grade thermal stability up to 125°C. The 800 MHz frequency offers higher performance than lower-speed variants like the D60. Consider the PBGA-324 footprint for PCB layout constraints. Verify peripheral requirements such as Ethernet, USB, and CAN interfaces match the application needs.

Part Context

This part belongs to the Texas Instruments Sitara AM335x series of microprocessors. These processors are designed for applications requiring advanced processing capabilities combined with real-time control features. The series supports various operating systems and includes integrated peripherals for connectivity and display management.

Replacement Considerations

AM3352BZCZD60: Lower clock speed (600 MHz), potentially different temperature range. AM3354BZCZD80: Higher clock speed (1 GHz), enhanced industrial protocols. Verify pin compatibility and software migration efforts when substituting.
