AM3352ZCE27

Overview

The AM3352ZCE27 is a microprocessor from the Texas Instruments Sitara AM335x series, featuring an ARM Cortex-A8 core. It operates at a maximum clock frequency of 270 MHz and utilizes a 32-bit data bus. The component is housed in a 298-pin PBGA package with surface mount installation. Key electrical parameters include a 1.1 V operating voltage and I/O voltages of 1.8 V and 3.3 V. It supports an industrial temperature range from -40°C to +125°C. Memory resources consist of 32 kB L1 instruction cache, 32 kB L1 data cache, and 256 kB L2 cache.

Feature Summary

• Integrates a single-core ARM Cortex-A8 processor for efficient computation.
• Includes a Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS) for independent real-time control.
• Features integrated graphics acceleration via a POWERVR SGX subsystem.
• Supports multiple communication interfaces including Ethernet, USB, CAN, and various serial protocols.

Applications

• Industrial automation controllers
• Smart energy metering systems
• Medical appliances
• Human-machine interface (HMI) panels

Procurement Notes

Verify the specific suffix 'ZCE27' against official Texas Instruments documentation to confirm the 270 MHz speed grade and industrial temperature rating. Ensure compatibility with required memory controllers and peripheral configurations before procurement. Cross-reference the package type and pinout with design specifications to prevent integration errors.

Selection Notes

Select this model when a balance of processing power and real-time capabilities is required for industrial applications. The 270 MHz speed suits moderate complexity tasks while the PRU-ICSS handles deterministic timing. Consider the wide operating temperature range for harsh environments. Evaluate if the integrated peripherals meet connectivity needs without external components.

Part Context

This component belongs to the Sitara AM335x family of microprocessors designed for cost-sensitive embedded applications. It shares architectural similarities with other variants like the AM3352BZCEA60 but differs in clock speed and thermal specifications. The series targets markets requiring Linux or Android support with robust industrial connectivity options.

Replacement Considerations

Direct substitutes within the same speed grade may be limited. Higher-speed variants like the AM3352BZCEA60 are functionally compatible but require verification of thermal management. Lower-speed models may not meet performance requirements. Always consult the latest datasheet for pin-to-pin compatibility and electrical parameter differences.
