Product details
Overview
R5F10267ASP#X5 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 A/D converter (11 channels), UART/CSI/I²C serial interfaces, 4-channel 16-bit timer, and operates from 1.8 V to 5.5 V at –40°C to +85°C - enabling use in battery-powered sensor nodes and smart appliance control panels.
For engineers reviewing the R5F10267ASP#X5 datasheet, R5F10267ASP#X5 pinout, R5F10267ASP#X5 application, or R5F10267ASP#X5 equivalent, key selection considerations include its 2 KB on-chip data flash with background operation, 2-channel DMA support, CRC hardware accelerator, and 63 μA/MHz active power consumption - critical for energy-constrained firmware update and real-time signal processing tasks.
Technical Context
The R5F10267ASP#X5 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting minimum instruction execution time of 0.04167 μs at 24 MHz using the high-accuracy ±1.0% on-chip oscillator. Its memory subsystem includes separate code flash (4 KB) and data flash (2 KB) with self-programming capability and flash shield window protection.
Peripheral integration centers on low-power operation: HALT/STOP/SNOOZE modes, on-chip voltage detector (12-level LVD), power-on-reset circuit, and dedicated low-speed 15 kHz watchdog timer. Serial connectivity is provided via one UART channel, two CSI (SPI-compatible) channels, and two simplified I²C channels - all configurable through peripheral I/O redirection register (PIOR).

FAQ
What is the maximum operating frequency of the R5F10267ASP#X5?
The R5F10267ASP#X5 supports a maximum system clock frequency of 24 MHz using its high-accuracy on-chip oscillator (±1.0% over –20°C to +85°C). External crystal oscillation up to 20 MHz is also supported via X1/X2 pins, with frequency range dependent on VDD voltage (1–20 MHz at 2.7–5.5 V; 1–8 MHz at 1.8–2.7 V).
Does the R5F10267ASP#X5 support in-system programming via its serial interfaces?
Yes, the R5F10267ASP#X5 supports in-system programming using the on-chip debug function and the SI01 pin (P125) configured as serial input. The device includes flash shield window protection and self-programming libraries (Type01 for code flash, Type04 for data flash) to enable secure firmware updates without external programmers.
How many analog input channels does the R5F10267ASP#X5 provide, and what is their resolution?
The R5F10267ASP#X5 integrates an 11-channel, 10-bit successive-approximation A/D converter with internal 1.45 V reference voltage and on-chip temperature sensor. Input channels include ANI0–ANI3 and ANI16–ANI22, supporting single-ended or differential measurements with programmable sample-and-hold timing.
What power-saving modes are available on the R5F10267ASP#X5, and what are their typical current draws?
The R5F10267ASP#X5 offers HALT (63 μA/MHz active), STOP (0.52 μA typical), and SNOOZE (2.5 μA with 10 μs wake-up) modes. STOP mode disables the CPU and most peripherals while retaining RAM and register contents; SNOOZE allows selected peripherals (e.g., UART, ADC) to operate autonomously during low-power wait states.
Is the R5F10267ASP#X5 pin-compatible with other RL78/G12 20-pin variants like R5F10268ASP#X5?
Yes, the R5F10267ASP#X5 shares identical 20-pin LSSOP package (PLSP0020JB-A), pinout, and electrical characteristics with all R5F102xxASP#X5 variants including R5F10268ASP#X5 and R5F10269ASP#X5 - enabling drop-in replacement for memory-scaling without PCB redesign.
