R5F100FCGFP#10

Description

This is a 16-bit RL78/G13 series microcontroller from Renesas Electronics, designed for embedded applications. It offers 32KB Flash program memory, 2KB RAM, and 4KB EEPROM, all in a 44-pin low-profile quad flat package (LQFP, 10x10 mm). The device integrates multiple communication and peripheral features, and is optimized for balanced performance and efficient power use. Based on advanced RL78 core architecture, it is suitable for moderate to complex control applications in a space-saving, surface-mount form.

Device Structure

Contains a single RL78 16-bit CPU core, Flash/EEPROM/RAM memory, and multiple analog/digital modules on one chip. Integrated with standard peripheral modules such as timers, communications controllers, and ADCs. The device uses a surface-mount, 44-pin LQFP package for compact installation on PCBs.

Performance Characteristics

Efficient 16-bit processing at 32 MHz offers fast response and lower power consumption.

32KB Flash allows complex firmware for embedded functions, while 2KB RAM and 4KB EEPROM support data storage and dynamic operations.

Multiple communication ports (CSI, I2C, LINbus, UART/USART) facilitate flexible connectivity in embedded systems.

Built-in peripherals support real-time control, system safety, hardware-based power management (POR, LVD), timers (PWM, WDT), and direct memory access (DMA).

Broad voltage and temperature operating ranges ensure flexibility in diverse environments.

Application Environments

Well-suited for general-purpose embedded control, small and medium home appliances, industrial control devices, portable equipment, sensor nodes, healthcare electronics, and automotive sub-systems (non-safety applications). The high reliability and wide operating range make it ideal for both consumer and industrial uses.

Selection Guidelines

Choose this microcontroller for applications requiring low to medium processing performance, moderate peripheral integration, and reasonable memory size within a compact form factor. Ideal for projects needing broad voltage/temperature tolerance, multiple communication options, and efficient power consumption. Assess your system I/O requirements and ensure 31 available lines are sufficient.

Usage Considerations

Confirm adequate memory (Flash/RAM/EEPROM) for your firmware and data needs.

Verify pinout and system power compatibility (2.4V to 5.5V supply).

Check for appropriate temperature range (−40°C to +105°C) for your environment.

Review interfacing peripherals and communication needs—ensure compatibility with existing protocols (I2C, LINbus, UART, etc.).

Consider MSL level 3 for reflow process control during surface mounting and proper storage before assembly.

Potential Equivalent/Replacement Models

There are various models in the RL78 family and competitor lines that may offer similar features:

Renesas: R5F100FCAFP#10 (same series, different package or I/O), R5F100FCHFP#10 (slightly different specs)

Renesas: Other RL78/G13 models with similar Flash/RAM sizes but different I/O counts or packages.

NXP: S08 or S12 series 16-bit MCUs (with different pinout and features—migration effort needed)

Microchip/Atmel: PIC16, PIC18, or ATmega series MCUs (differences in architecture and pinouts)

Texas Instruments: MSP430 series (might vary in peripherals or performance)
