Product details
Overview
R5F102A7GSP#30 from Renesas Electronics is a 30-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller with 4 KB code flash, 2 KB data flash, and 512 B RAM, operating from 1.8 V to 5.5 V at –40°C to +105°C. It integrates an 8-channel 16-bit timer, 8-channel 10-bit ADC, UART/CSI/I²C serial interfaces, DMA controller, and high-accuracy ±1.0% on-chip oscillator - deployed in industrial motor control and sensor node firmware.
For engineers reviewing the R5F102A7GSP#30 datasheet, R5F102A7GSP#30 pinout, R5F102A7GSP#30 application, or R5F102A7GSP#30 equivalent, this page delivers verified electrical specs, package mapping, functional pin roles, real-world use cases, and two validated alternative parts for thermal-grade embedded designs requiring data flash persistence and low-voltage operation.
Technical Context
The R5F102A7GSP#30 implements the RL78 CPU core with 3-stage CISC pipeline, supporting instruction execution times from 0.04167 µs (24 MHz) to 1 µs (1 MHz). Its power architecture includes HALT, STOP, and SNOOZE modes enabling 63 µA/MHz active current draw and sub-µA standby consumption.
It features dual on-chip oscillators: a high-speed 1–24 MHz oscillator (±1.0% accuracy over –20°C to +85°C) and a 15 kHz low-speed oscillator for watchdog and interval timing. The device supports background operation (BGO) for concurrent code execution during 2 KB data flash rewriting - rated for 1,000,000 write cycles at full VDD range.
