Product details
Overview
R5F10367ASP#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 features 2 KB code flash, 256 B RAM, 10-bit 8-channel ADC, 4-channel 16-bit timer, UART, and operates from 1.8 V to 5.5 V with HALT/STOP/SNOOZE low-power modes - deployed in smart home sensors and battery-powered IoT edge nodes.
For engineers reviewing the R5F10367ASP#X5 datasheet, R5F10367ASP#X5 pinout, R5F10367ASP#X5 application, or R5F10367ASP#X5 equivalent, key selection criteria include its 20-pin LSSOP-20 package, absence of data flash memory, single UART channel, no DMA or safety functions (CRC/RAM guard), and ±5.0% high-speed on-chip oscillator accuracy over –40°C to +85°C.
Technical Context
The R5F10367ASP#X5 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and supports instruction execution times from 0.04167 µs (@24 MHz on-chip oscillator) to 1 µs (@1 MHz). Its clock system integrates a high-speed on-chip oscillator (1–24 MHz selectable) and low-speed 15 kHz on-chip oscillator, with power-on-reset and 12-level voltage detector for robust reset management.
Peripheral integration includes one UART channel (RxD0/TxD0), simplified SPI (CSI00), no I²C interface, 4-channel TAU0 timer with PWM capability, and 8-channel 10-bit A/D converter with internal reference (1.45 V) and temperature sensor - all configured via dedicated SFRs without peripheral I/O redirection in default PIOR=00H state.

FAQ
What is the maximum operating frequency of the R5F10367ASP#X5?
The R5F10367ASP#X5 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator. When driven by an external crystal (X1/X2), the maximum main system clock is 20 MHz under VDD ≥ 2.7 V, or 16 MHz under VDD ≥ 2.4 V. Instruction execution time ranges from 0.04167 µs (24 MHz) to 1 µs (1 MHz), enabling deterministic real-time response in time-critical applications.
Does the R5F10367ASP#X5 include data flash memory?
No, the R5F10367ASP#X5 does not include data flash memory. Per the RL78/G12 datasheet Section 1.3.1, data flash (2 KB) is mounted only on R5F102 products; R5F103 series devices like the R5F10367ASP#X5 omit this feature. Applications requiring non-volatile parameter storage must use code flash with self-programming or external EEPROM/FRAM.
What are the UART capabilities of the R5F10367ASP#X5?
The R5F10367ASP#X5 includes exactly one UART channel (UART0), accessible on P11 (RxD0) and P12 (TxD0) in default configuration. It supports standard asynchronous communication with programmable baud rates, framing, and parity. Remapped UART0 functionality is available on P61 (RxD0) and P60 (TxD0) via peripheral I/O redirection register (PIOR) settings, providing layout flexibility for PCB routing.
Can the R5F10367ASP#X5 operate from a 1.8 V supply?
Yes, the R5F10367ASP#X5 is fully specified to operate from 1.8 V to 5.5 V. At 1.8 V, it supports up to 8 MHz system clock in LS (low-speed main) mode and retains full functionality including ADC, timers, and UART - making it ideal for single-cell Li-ion or alkaline battery-powered devices where low-voltage operation is essential.
What low-power modes are supported by the R5F10367ASP#X5?
The R5F10367ASP#X5 supports three primary low-power modes: HALT (CPU halted, peripherals active), STOP (all clocks stopped, RAM retained), and SNOOZE (selected peripherals remain active for wake-up events). These modes achieve sub-µA standby current and enable rapid wake-up (< 4 µs from HALT), critical for duty-cycled sensor applications requiring extended battery life.
