Microcontrollers Procurement Notes

Verify the specific suffix AA0 against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding pinout and electrical specifications before procurement. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and current availability status.

Microcontrollers Selection Notes

Select this component when a cost-effective ARM Cortex-M23 solution with moderate memory capacity is required. The 48 MHz speed and 32 kB flash are suitable for basic control tasks. Consider the 48-pin LFQFP package for surface mount assembly. Evaluate peripheral needs against the available I2C, SPI, and ADC resources to ensure sufficient interface coverage for the target application.

Microcontrollers Part Context

This microcontroller belongs to the RA2E1 group, designed for entry-level applications. It shares architectural similarities with other RA family members but offers specific memory and pin configurations. The RA2E1 series targets cost-sensitive markets while providing modern ARM architecture benefits and comprehensive peripheral sets for general-purpose use.

Microcontrollers Replacement Considerations

Check for suffix variations like BA0 which may indicate different packaging or testing criteria. Verify if alternative packages within the same RA2E1 series meet physical space requirements. Ensure functional equivalence in terms of core speed, memory size, and peripheral availability when considering substitutes.
