AM3703CBCA

Overview

The AM3703CBCA 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 and utilizes a PBGA-515 package. The device includes 32 kB L1 instruction cache, 32 kB L1 data cache, and 256 kB L2 cache. It supports floating-point operations and functions within a supply voltage range of 900 mV to 1.2 V. Operating temperatures span from -40°C to +105°C.

Feature Summary

• Integrates an ARM Cortex-A8 processor core for high-performance computing tasks.
• Includes hardware support for floating-point arithmetic operations.
• Features integrated memory structures including L1/L2 caches and ROM.

Applications

• Industrial control systems
• Medical devices
• Smart meters

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as indicated in official documentation. Check for moisture sensitivity handling requirements during storage and assembly. Ensure compatibility with existing PCB layouts regarding the PBGA-515 footprint. Validate that the specific suffix matches design specifications.

Selection Notes

Select this model when a single-core ARM Cortex-A8 solution is required for embedded applications. Consider the 800 MHz performance ceiling and PBGA-515 package constraints. Evaluate thermal management needs given the extended temperature range. Compare against other Sitara variants if higher core counts or different interfaces are necessary.

Part Context

This component belongs to the Sitara microprocessor series by Texas Instruments. It is designed for general-purpose embedded processing. The part shares architectural similarities with other AM37xx models but differs in specific interface configurations and packaging options. It represents a segment of TI's portfolio focused on efficient, scalable processing solutions.

Replacement Considerations

The AM3703CUSD100 serves as a functional substitute with identical core architecture but operates at a higher 1 GHz frequency. Both parts share the same Sitara lineage and ARM Cortex-A8 base. Designers should verify pinout compatibility and thermal characteristics when transitioning between these specific part numbers.
