Renesas R5F10367ASP#V0

Overview

R5F10367ASP#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, 256 B RAM, 10-bit 8-channel ADC, 4-channel 16-bit TAU timer, UART, and simplified SPI (CSI), operating from 1.8 V to 5.5 V at up to 24 MHz - delivering 31 DMIPS while consuming only 63 μA/MHz in active mode. It targets battery-powered sensor nodes and appliance control panels requiring reliable low-voltage operation and integrated analog peripherals.

For engineers reviewing the R5F10367ASP#V0 datasheet, R5F10367ASP#V0 pinout, R5F10367ASP#V0 application, or R5F10367ASP#V0 equivalent, key selection criteria include its 20-pin LSSOP-20 package, absence of data flash memory, single UART channel, no DMA or CRC hardware, and ±5.0% high-speed on-chip oscillator accuracy over –40°C to +85°C - all critical for footprint-constrained, low-cost timing- and interface-sensitive designs.

Technical Context

The R5F10367ASP#V0 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.04167 μs (at 24 MHz) to 1 μs (at 1 MHz). Its clock system combines a high-speed on-chip oscillator (selectable 1–24 MHz, ±5.0% accuracy) with external crystal support (1–20 MHz) and a dedicated 15 kHz low-speed on-chip oscillator for watchdog and interval timing.

Peripheral integration includes one UART channel, one simplified SPI (CSI) channel, no I²C interface, four 16-bit timer channels with PWM capability, an 8-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and five external interrupt pins (INTP0–INTP3 plus P137). It lacks DMA, data flash, and safety features like CRC or RAM/SFR guard found in R5F102 variants.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F10367ASP#V0?

The R5F10367ASP#V0 operates at up to 24 MHz using its high-speed on-chip oscillator, achieving 31 DMIPS performance. This benchmark reflects integer instruction throughput under standard conditions and is validated in Renesas' RL78/G12 documentation. The R5F10367ASP#V0 maintains this performance across its full 1.8–5.5 V supply range and –40°C to +85°C ambient temperature.

Does the R5F10367ASP#V0 include data flash memory, and how does that affect firmware update capability?

No, the R5F10367ASP#V0 does not include data flash memory - unlike R5F102-series parts which integrate 2 KB. This means the R5F10367ASP#V0 cannot perform background data writes or store calibration tables in dedicated nonvolatile memory. Firmware updates must use code flash with self-programming libraries, requiring careful RAM allocation and interrupt management during write cycles.

What are the supported serial communication interfaces on the R5F10367ASP#V0, and are there hardware I²C capabilities?

The R5F10367ASP#V0 supports one UART channel and one simplified SPI (CSI) channel. It does not include hardware I²C - the SCLA0/SDAA0 pins are present but function only as general-purpose I/O or remappable UART lines per the datasheet. True I²C communication requires bit-banging or external bridge ICs, unlike R5F102 variants that provide dedicated IICA0 hardware.

How many analog input channels and what A/D resolution does the R5F10367ASP#V0 provide?

The R5F10367ASP#V0 integrates an 8-channel, 10-bit successive-approximation A/D converter with internal 1.45 V reference voltage and on-die temperature sensor. Channels include ANI0–ANI3 and ANI16–ANI22 (8 total), supporting single-ended measurements referenced to AVREFP/AVREFM. No external reference or calibration is required for typical ±2% accuracy applications.

What low-power modes are available on the R5F10367ASP#V0, and what is the typical current draw in STOP mode?

The R5F10367ASP#V0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with RTC disabled and only RESET and INTP0 enabled for wake-up, typical current consumption is less than 0.5 μA at 3.3 V and 25°C. This enables multi-year battery operation in infrequently sampled sensor applications, with wake-up latency under 10 μs from STOP to active execution.
