R5F2L38AMNFA#V0

Microcontrollers Overview

The R5F2L38AMNFA#V0 is a 16-bit microcontroller from the Renesas R8C/L38A series, utilizing the R8C CPU core. It features 128KB of flash memory and 10KB of RAM, operating within a voltage range of 2.7V to 5.5V. The device supports clock frequencies up to 20MHz and includes integrated peripherals such as I2C interfaces, UARTs, and PWM units. Packaged in an 80-pin LFQFP format, it is designed for efficient instruction execution with a built-in multiplier.

Microcontrollers Feature Summary

• Integrates the R8C CPU core with a powerful instruction set and hardware multiplier for high-speed processing.
• Supports background operation of data flash for non-volatile storage management without halting main program execution.
• Maximizes electromagnetic interference and susceptibility performance through optimized design.
• Combines multiple peripheral functions including multifunction timers and serial interfaces to reduce system component count.

Microcontrollers Applications

• Household appliances
• Office equipment
• Audio equipment
• Consumer products

Microcontrollers Procurement Notes

Verify current lifecycle status before integration, as this component may be classified as Not Recommended for New Designs or End-of-Life. Confirm availability through authorized Renesas distributors and check for specific environmental compliance documentation required for your region. Ensure that existing supply chains can support long-term maintenance if selected for legacy systems.

Microcontrollers Selection Notes

Select this MCU for designs requiring robust 16-bit processing with low power consumption and high EMI/EMS resilience. It is suitable for applications needing integrated flash background operations and multiple communication interfaces. Consider the 80-pin package constraints and verify that the 20MHz maximum frequency meets real-time control requirements.

Microcontrollers Part Context

This part belongs to the R8C/L38A group of single-chip microcontrollers, which are supported primarily for customers who have already adopted these products. The RL78 series is recommended for new designs instead. These MCUs incorporate the R8C CPU core, supporting a 1Mb address space and offering low power consumption with various operating modes for additional power control.

Microcontrollers Replacement Considerations

Renesas recommends transitioning to the RL78/L13 or RL78/L1C groups for new designs. Verify pin-to-pin compatibility and software migration efforts when considering alternative parts from the same manufacturer or other vendors.
