Product details
Overview
R5F10269GSP#X5 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller designed for industrial temperature-grade embedded control. It integrates 12 KB code flash, 2 KB data flash, 768 B RAM, 10-bit A/D converter (11 channels), and operates from 1.8 V to 5.5 V across –40°C to +105°C ambient. Its key role is real-time sensor interfacing and actuator control in battery-powered industrial monitoring nodes.
For engineers reviewing the R5F10269GSP#X5 datasheet, R5F10269GSP#X5 pinout, R5F10269GSP#X5 application, or R5F10269GSP#X5 equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial-temperature operation, and direct alternative part comparisons - all grounded in Renesas' official R01DS0193EJ0250 Rev.2.50 documentation.
Technical Context
The R5F10269GSP#X5 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting 1 MB address space and 31 DMIPS at 24 MHz. It features dual on-chip oscillators: high-speed (1–24 MHz, ±1.0% accuracy at –20°C to +85°C) and low-speed (15 kHz), enabling precise timing and ultra-low-power HALT/STOP/SNOOZE modes.
Peripheral integration includes two CSI channels, one UART, two simplified I²C interfaces, four 16-bit TAU timer channels, DMA controller (2 channels), CRC engine, and RAM/SFR guard for functional safety. All peripherals are accessible via 18 I/O pins, including six N-ch open-drain ports with 6 V tolerance and analog inputs with internal 1.45 V reference and temperature sensor.
