Product details
Overview
R5F10367ASM#15 from Renesas is a 20-pin TSSOP-packaged RL78/G12 16-bit microcontroller designed for ultra-low-power general-purpose embedded control. It features 2 KB code flash, 256 B RAM, 1.8–5.5 V operation, 24 MHz high-speed on-chip oscillator (±5% accuracy), and operates across –40°C to +85°C for consumer applications - used in battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F10367ASM#15 datasheet, R5F10367ASM#15 pinout, R5F10367ASM#15 application, or R5F10367ASM#15 equivalent, key selection criteria include its 20-pin TSSOP package, absence of data flash memory, single UART channel, no DMA controller, and lack of simplified I²C interface - all confirmed for this specific variant.
Technical Context
The R5F10367ASM#15 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and supports HALT/STOP/SNOOZE low-power modes. Its instruction execution time ranges from 0.04167 µs (@24 MHz high-speed on-chip oscillator) to 1 µs (@1 MHz).
It integrates an 8/10-bit 11-channel A/D converter with internal 1.45 V reference and temperature sensor, four 16-bit timer channels, one watchdog timer, and one 12-bit interval timer - all operating within the 1.8–5.5 V supply range and –40°C to +85°C ambient temperature rating.

FAQ
What is the maximum operating frequency and oscillator accuracy of the R5F10367ASM#15?
The R5F10367ASM#15 supports a maximum high-speed on-chip oscillator frequency of 24 MHz with ±5.0% accuracy over the full –40°C to +85°C operating range. It does not support external crystal oscillation above 20 MHz in HS mode, and lacks the tighter ±1.0% oscillator tolerance found in R5F102-series variants.
Does the R5F10367ASM#15 include data flash memory or DMA capability?
No, the R5F10367ASM#15 does not include data flash memory or a DMA controller. These features are exclusive to the R5F102-series counterparts (e.g., R5F10267ASM#15). The R5F10367ASM#15 provides only 2 KB code flash and relies on software-managed data movement between peripherals and RAM.
Which serial communication interfaces are supported on the R5F10367ASM#15?
The R5F10367ASM#15 supports one UART channel (RxD0/TxD0), one simplified SPI (CSI) channel (SCK00/SI00/SO00), and no I²C interface - unlike R5F102-series parts which include simplified I²C. The SCLA0/SDAA0 pins are physically present but functionally unimplemented for I²C in this variant.
What are the analog capabilities of the R5F10367ASM#15?
The R5F10367ASM#15 integrates an 8/10-bit A/D converter with 11 input channels (ANI0–ANI3, ANI16–ANI22), internal 1.45 V reference voltage, and an on-chip temperature sensor. It supports single-ended and differential measurements, with AVREFP/AVREFM pins enabling precision ratiometric sensing independent of VDD variation.
Is the R5F10367ASM#15 pin-compatible with other RL78/G12 20-pin variants?
Yes, the R5F10367ASM#15 shares identical TSSOP-20 pinout and footprint with all other RL78/G12 20-pin variants (e.g., R5F10267ASM#15, R5F10368ASM#15). However, functional differences - such as absence of data flash, DMA, or I²C - require firmware and schematic validation before substitution.
