Product details
Overview
R5F10269ASP#X5 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 MCU designed for cost-sensitive consumer and industrial control applications. It integrates 12 KB code flash, 2 KB data flash, 768 B RAM, 10-bit 11-channel ADC, and operates from 1.8 V to 5.5 V with true low-power operation (63 μA/MHz). It delivers 31 DMIPS at 24 MHz and supports HALT/STOP/SNOOZE modes - ideal for battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F10269ASP#X5 datasheet, R5F10269ASP#X5 pinout, R5F10269ASP#X5 application, or R5F10269ASP#X5 equivalent, key selection criteria include its 20-pin LSSOP-20 package, integrated 2 KB data flash with background operation (BGO), 2-channel DMA, CRC engine, and support for UART + dual CSI/I²C interfaces - all within a -40°C to +85°C industrial temperature grade.
Technical Context
The R5F10269ASP#X5 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.04167 µs min @ 24 MHz). Its clock system combines a high-accuracy ±1.0% on-chip oscillator (1–24 MHz) with external crystal support (1–20 MHz) and a dedicated 15 kHz low-speed oscillator for watchdog and interval timing.
Peripheral integration includes TAU0 16-bit timer (4 channels), windowed watchdog timer, 12-bit interval timer, SAU0 serial array unit supporting UART/CSI/I²C, and programmable buzzer/clock output. Safety features include RAM guard, SFR guard, and CRC calculation hardware - all confirmed for the R5F102xx series per datasheet Section 1.3.3.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F10269ASP#X5?
The R5F10269ASP#X5 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. This is confirmed in the RL78/G12 datasheet (R01DS0193EJ0250, Rev.2.50, Page 1). The core executes instructions in as little as 0.04167 µs at this speed, enabling responsive real-time control in compact firmware.
Does the R5F10269ASP#X5 include data flash memory, and what is its endurance specification?
Yes, the R5F10269ASP#X5 integrates 2 KB of data flash memory with 1,000,000 write/erase cycles (typical) and supports background operation (BGO), allowing program execution during flash writes. This is explicitly stated in the datasheet Section 1.1 Features and Table 1-1, distinguishing it from R5F103-series variants which omit data flash.
What are the supported serial communication interfaces on the R5F10269ASP#X5?
The R5F10269ASP#X5 supports 1 UART channel, 2 simplified SPI (CSI) channels, and 2 simplified I²C channels - all confirmed for 20-pin R5F1026x devices in Section 1.7 Outline of Functions (Page 15). These interfaces share pins via peripheral I/O redirection, enabling flexible multi-protocol connectivity without additional ICs.
What is the operating temperature range and industrial qualification of the R5F10269ASP#X5?
The R5F10269ASP#X5 is rated for TA = –40°C to +85°C and belongs to the "A" field-of-application group (consumer/industrial), as indicated by the "A" in its part number suffix. It meets industrial reliability requirements including 12-level voltage detector and robust ESD tolerance, per datasheet Sections 1.1 and 2.1.
How does the R5F10269ASP#X5 support low-power operation in battery-powered systems?
The R5F10269ASP#X5 achieves 63 μA/MHz active current and supports HALT, STOP, and SNOOZE low-power modes.
