R5F21262SNFP#X6

Microcontrollers Overview

The R5F21262SNFP#X6 is a 16-bit microcontroller from the Renesas R8C/26 series, featuring an R8C core. It integrates 8KB of flash memory and 1KB of RAM within a 32-LQFP package. The device operates on a 3V or 5V supply voltage and supports a maximum clock frequency of 20MHz. It includes built-in peripherals such as I2C, LINbus, SIO, SSU, and UART/USART interfaces, along with LED drivers, POR, voltage detection, and WDT functions. The component is rated for an operating temperature range of -20°C to +85°C.

Microcontrollers Feature Summary

• Integrates 8KB flash memory and 1KB RAM for code and data storage
• Supports multiple communication protocols including I2C, LINbus, and UART
• Includes dedicated LED driver capabilities for display applications
• Features internal oscillator and hardware monitoring functions

Microcontrollers Applications

• Consumer electronics requiring low pin count control
• Industrial control systems utilizing LINbus communication
• Appliance logic boards with LED indication needs
• Battery-powered devices compatible with 3V operation

Microcontrollers Procurement Notes

Verify the specific suffix #X6 against official Renesas documentation to confirm reel packaging and moisture sensitivity level requirements. Confirm current lifecycle status, as R8C/26 series components may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for the 32-LQFP package before procurement.

Microcontrollers Selection Notes

Select this model when 8KB program memory suffices for application logic. Choose the 32-pin LQFP package for space-constrained designs requiring fewer I/O lines than larger variants. Verify that the 3V/5V operating range aligns with the system power supply architecture and that LINbus support meets network requirements.

Microcontrollers Part Context

This part belongs to the R8C/26 family, designed for cost-sensitive embedded applications. It shares architectural similarities with other R8C/2x series members but offers distinct memory configurations. The 32-LQFP package provides a compact surface-mount solution suitable for high-density board layouts.

Microcontrollers Replacement Considerations

Check for direct substitutes within the R8C/26 series with matching memory sizes. Consider R5F21262SNFP#V2 for tray-packaged alternatives if reel availability is limited. Verify pinout compatibility before substituting with higher-memory variants like the R5F21264.
