Product details
Overview
R5F10268GSP#X5 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 MCU with 8 KB code flash, 2 KB data flash, and 512 B RAM, operating from 1.8 V to 5.5 V across –40°C to +105°C industrial temperature range. It delivers 31 DMIPS at 24 MHz, integrates an 11-channel 10-bit A/D converter, dual simplified SPI/I²C interfaces, UART, and DMA controller - deployed in battery-powered sensor nodes and industrial control panels requiring deterministic real-time response and long-term firmware update capability.
For engineers reviewing the R5F10268GSP#X5 datasheet, R5F10268GSP#X5 pinout, R5F10268GSP#X5 application, or R5F10268GSP#X5 equivalent, this page provides verified technical context on its HALT/STOP/SNOOZE power modes, high-accuracy ±1.0% on-chip oscillator (–20°C to +85°C), CRC hardware accelerator, RAM guard, and key interrupt support - all critical for low-energy embedded design validation and migration planning.
Technical Context
The R5F10268GSP#X5 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space, enabling efficient execution of mixed-signal control firmware. Its dual-channel DMA supports background transfers between SFRs and internal RAM in just 2 clocks per 8/16-bit operation - essential for concurrent analog acquisition and serial communication without CPU load.
It features a dedicated low-speed on-chip oscillator (15 kHz) for watchdog timer operation independent of main clock domain, plus hardware CRC calculation and RAM/SFR guard logic - confirming its suitability for functional safety-aware applications where memory integrity and fault detection are mandatory.
