Product details
Overview
R5F10267ASP#V0 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller designed for cost-sensitive consumer and industrial embedded control. It integrates 4 KB code flash, 2 KB data flash, 256 B RAM, 10-bit 11-channel ADC, 4-channel 16-bit TAU timer, UART/CSI/I²C serial interfaces, and operates from 1.8 V to 5.5 V with true low-power HALT/STOP/SNOOZE modes - enabling battery-powered sensor nodes and smart appliance control panels.
For engineers reviewing the R5F10267ASP#V0 datasheet, R5F10267ASP#V0 pinout, R5F10267ASP#V0 application, or R5F10267ASP#V0 equivalent, key selection criteria include its 4 KB flash + 2 KB data flash pairing, 20-pin LSSOP-20 package with 18 I/Os (including 2× 6-V-tolerant N-ch open-drain), integrated CRC and RAM guard safety features, and high-accuracy ±1.0% on-chip oscillator across –40°C to +85°C.
Technical Context
The R5F10267ASP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, delivering 31 DMIPS at 24 MHz while consuming only 63 μA/MHz. Its memory subsystem includes dedicated 2 KB data flash supporting background operation (BGO) and 1,000,000 write cycles, alongside code flash with block erase prohibition for security.
Peripherals are optimized for mixed-signal control: dual CSI channels (SPI-compatible), one UART, two simplified I²C interfaces, 11-channel ADC with internal 1.45 V reference and temperature sensor, and DMA controller with 2 channels for efficient peripheral-to-memory transfers without CPU intervention.
