R5F21367CDFA#V0

Microcontrollers Overview

The R5F21367CDFA#V0 is a 16-bit microcontroller from the Renesas R8C series, featuring the R8C CPU core. It is housed in a 64-pin LQFP package and supports a maximum operating frequency of 20MHz. The device includes 128kB of Flash program memory and 10kB of RAM. Key peripherals include three UART channels, two I2C interfaces, one LIN channel, and a single 12-bit analog-to-digital converter with ten channels.

Microcontrollers Feature Summary

• Integrates the R8C CPU core with a built-in multiplier for high-speed processing efficiency.
• Features data flash with background operation capability to support non-intrusive code updates.
• Optimized design to maximize electromagnetic interference and immunity performance.
• Combines multiple peripheral functions such as timers and serial interfaces to reduce system component count.

Microcontrollers Applications

• Household appliances
• Office equipment
• Audio equipment

Microcontrollers Procurement Notes

Verify the specific suffix V0 against official Renesas documentation to confirm pinout and voltage compatibility. Check current product status as R8C models may be designated NRND or obsolete. Confirm moisture sensitivity levels and storage conditions prior to assembly to ensure reliability.

Microcontrollers Selection Notes

Select this model for applications requiring robust EMI/EMS performance and efficient code execution within a 64-pin form factor. Evaluate if the 20MHz clock speed and 128kB memory meet project requirements. Consider alternative RL78 series devices for new designs if higher performance or modern features are needed.

Microcontrollers Part Context

This component belongs to the R8C family of 16-bit microcontrollers designed for general-purpose control tasks. The R8C architecture emphasizes low power consumption and high integration, making it suitable for cost-sensitive embedded systems where space and efficiency are critical constraints.

Microcontrollers Replacement Considerations

Renesas recommends the RL78/L13 and RL78/L1C groups for new designs instead of the R8C/L38M group. Verify functional equivalence and pin compatibility before substituting with other R8C variants or migrating to the RL78 platform.
