Overview
R5F10268GSP#V5 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 8 KB code flash, 2 KB data flash, 512 B RAM, 10-bit A/D converter (11 channels), and operates from 1.8 V to 5.5 V with true low-power consumption (63 μA/MHz). It delivers 31 DMIPS at 24 MHz and supports STOP/HALT/SNOOZE modes - ideal for battery-powered sensor nodes and industrial HMI panels.
For engineers reviewing the R5F10268GSP#V5 datasheet, R5F10268GSP#V5 pinout, R5F10268GSP#V5 application, or R5F10268GSP#V5 equivalent, key selection criteria include its G-grade (–40°C to +105°C) operation, on-chip 2 KB data flash with background operation (BGO), dual CSI/I²C serial interfaces, 2-channel DMA, and CRC hardware acceleration - all in a compact 4.4 × 6.5 mm LSSOP-20 package.
