R5F100JHAFA#30 Features
This RL78 G13 microcontroller delivers a balanced mix of performance, memory, and connectivity for mainstream embedded designs. The 16 bit RL78 core running up to 32 MHz provides efficient code execution and low power operation, while 192 KB on chip Flash and 16 KB RAM accommodate substantial firmware with room for communication stacks and application logic. The integrated 8 KB data flash or EEPROM like storage supports non volatile parameters, logs, and calibration data without external memory.
The device integrates versatile serial interfaces including UART or USART for asynchronous communication, CSI for SPI like synchronous transfers, and IC for I2C style control buses. LIN bus support enables simple networking in appliances and general machinery where lightweight serial communication is preferred. The 12 channel analog to digital converter offers selectable 8 or 10 bit resolution, suitable for sensor inputs, voltage monitoring, and user interface analog measurements.
A rich peripheral set enhances real time control. Multiple PWM capable timers drive motors, actuators, and LEDs with accurate duty cycle control. The DMA engine offloads data movement to improve throughput and reduce CPU load. The internal oscillator simplifies the clock tree and can reduce bill of materials by eliminating an external crystal in many use cases.
Robust operation is supported by safety oriented hardware. Low voltage detection helps the system respond gracefully to brown outs. Power on reset ensures correct startup behavior. The watchdog timer provides fault recovery from software hang conditions. Together with the wide supply range from 1.6 V to 5.5 V, the device operates reliably from batteries, regulated rails, or USB derived supplies.
The 52 LQFP package with 38 available general purpose I O pins gives ample digital connectivity while staying compact on the PCB. Ports are multiplexed to map peripheral functions where needed, allowing flexible pin assignment during design. The surface mount package is compatible with standard SMT assembly and reflow processes.
R5F100JHAFA#30 Quality and Safety Features
The microcontroller includes multiple hardware features that reinforce quality and operational safety in embedded products. Low voltage detection and power on reset protect against improper supply conditions and help maintain predictable system states during power transients. The watchdog timer enables recovery from firmware faults, improving system availability. On chip Flash and data flash simplify traceability and configuration retention by keeping software and parameters within a single qualified component. The device is RoHS3 compliant, supporting environmentally responsible manufacturing. Recommended ESD handling procedures and moisture controls during assembly should be followed for plastic LQFP packages, and thermal performance should be validated on the target PCB to maintain safe junction temperatures across the full operating range.
