AM3874CCYE80

Overview

The AM3874CCYE80 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 includes 512 kB of L2 cache and 64 kB of data RAM. It supports I/O voltages of 1.5 V, 1.8 V, and 3.3 V, and functions within a temperature range of -40°C to +105°C. The processor utilizes a PBGA-684 package.

Feature Summary

• Integrates an ARM Cortex-A8 core for embedded processing tasks
• Supports multiple interface protocols including PCIe, USB, SPI, UART, and I2C
• Features floating-point instruction support for computational efficiency

Applications

• Industrial automation controllers
• Medical imaging systems
• Smart grid infrastructure devices

Procurement Notes

Verify the specific suffix 'E80' against official Texas Instruments documentation to confirm the exact operating temperature range and packaging configuration. Ensure compatibility with required I/O voltage levels (1.5 V, 1.8 V, or 3.3 V) during system design validation. Cross-reference the datasheet for moisture sensitivity level requirements and recommended soldering profiles to prevent component damage during assembly.

Selection Notes

Select this component when an industrial-grade temperature range (-40°C to +105°C) is required, distinguishing it from commercial variants like the AM3871. Evaluate the need for the specific 800 MHz performance and 512 kB L2 cache capacity relative to application latency constraints. Confirm that the PBGA-684 package footprint aligns with the target PCB layout capabilities.

Part Context

This part belongs to the Texas Instruments Sitara AM38xx series, designed for high-performance embedded applications. It shares architectural similarities with other Cortex-A8 based processors in the lineup but differs in thermal ratings and specific peripheral configurations. The series targets demanding environments requiring robust processing power and extensive connectivity options.

Replacement Considerations

The AM3871CCYE80 is a related variant within the same family; however, it typically features a commercial temperature range rather than the industrial rating of the AM3874. Verify if the extended temperature capability is critical before substituting.
