R5F21256SYFP#V2

Microcontrollers Overview

The R5F21256SYFP#V2 is a 16-bit microcontroller from the Renesas R8C/2x/25 series, featuring an R8C/Tiny CPU core. It integrates 32KB of flash program memory and 2KB of RAM. The device operates at a maximum frequency of 20MHz with an internal oscillator. It supports a supply voltage range of 2.2V to 5.5V and includes 12-channel 10-bit A/D converters. Connectivity options include I2C, LINbus, SIO, SSU, and UART/USART interfaces. The component is housed in a 52-LQFP (10x10mm) surface-mount package and functions within a temperature range of -20°C to 85°C.

Microcontrollers Feature Summary

• Integrates 12-channel 10-bit analog-to-digital conversion capabilities for sensor interfacing.
• Supports multiple communication protocols including LINbus, I2C, and UART for system connectivity.
• Includes hardware peripherals such as a watchdog timer and power-on reset for system reliability.

Microcontrollers Applications

• Automotive body electronics and interior control modules
• Industrial control systems requiring LINbus communication

Microcontrollers Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprints for the 52-LQFP package. Confirm moisture sensitivity level handling requirements during assembly. Validate that the operating voltage range aligns with the target system design specifications.

Microcontrollers Selection Notes

Select this component when a 16-bit architecture with integrated flash and robust automotive-grade communication interfaces is required. Consider the 52-pin LQFP package constraints for board layout. Evaluate the 20MHz processing speed against application latency requirements. Ensure the 2.2V to 5.5V supply range matches the available power rails in the final product design.

Microcontrollers Part Context

This part belongs to the Renesas R8C/2x/25 family of 16-bit microcontrollers. The R8C series is designed for cost-sensitive applications requiring moderate performance and peripheral integration. The R5F21256 variant specifically offers 32KB of flash memory, distinguishing it from lower-capacity models in the same series while maintaining the same physical footprint and core functionality.

Microcontrollers Replacement Considerations

Direct substitutes within the R8C/25 series may include parts with identical pinouts but different memory sizes, such as the R5F21258SNFP#V2. Verify functional equivalence regarding peripheral availability and software compatibility before substitution.
