Product details
Overview
R5F10367ASM#35 from Renesas is a 20-pin RL78/G12 16-bit microcontroller with 2 KB code flash, 256 B RAM, and no data flash memory, operating at 1.8–5.5 V across –40 to +85 °C for consumer applications. It features a 24 MHz high-speed on-chip oscillator (±5% accuracy), 10-bit 11-channel ADC, 4-channel 16-bit timer, UART, and simplified SPI (CSI) for embedded control in space-constrained devices.
For engineers reviewing the R5F10367ASM#35 datasheet, R5F10367ASM#35 pinout, R5F10367ASM#35 application, or R5F10367ASM#35 equivalent, key selection criteria include its TSSOP20 package, absence of DMA and data flash, ±5% oscillator tolerance, 18 I/O pins (including 2× 6-V-tolerant N-ch open-drain), and suitability for low-power sensor interface and appliance control where cost and footprint are critical.
Technical Context
The R5F10367ASM#35 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 31 DMIPS at 24 MHz. Its power management includes HALT, STOP, and SNOOZE modes enabling 63 μA/MHz active current draw.
Peripheral integration centers on UART0, CSI00, and a 10-bit A/D converter with internal 1.45 V reference and temperature sensor. The device lacks DMA, CRC, safety guards, and simplified I²C-features present only in R5F102-series variants-making it optimized for deterministic real-time control over complex data handling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10267ASM#35 | Includes 2 KB data flash, CRC engine, RAM guard, and ±1% oscillator accuracy - adds 1.5 KB RAM vs. 256 B | Required for field firmware updates, secure boot, or data logging; unsuitable where cost or code-only storage suffices | Select when persistent parameter storage or enhanced safety features are mandatory |
| R5F10368ASM#35 | Doubles code flash to 4 KB and RAM to 512 B; retains identical peripherals, package, and oscillator spec | Needed for larger firmware images (e.g., USB stack, OTA bootloader) without changing PCB layout or timing constraints | Choose when application growth requires more program memory but same I/O and power profile |
Compared with R5F10267ASM#35, the R5F10367ASM#35 trades data flash and tighter oscillator tolerance for lower unit cost and smaller silicon die; versus R5F10368ASM#35, it offers minimal memory footprint for deeply embedded control where code size is tightly constrained.

FAQ
What is the maximum operating frequency and instruction throughput of the R5F10367ASM#35?
The R5F10367ASM#35 operates at up to 24 MHz using its high-speed on-chip oscillator, achieving 31 DMIPS performance. Its minimum instruction execution time is 0.04167 µs at 24 MHz, and the RL78 CPU core uses a 3-stage pipeline to deliver deterministic real-time response. The R5F10367ASM#35 does not support external crystal frequencies above 20 MHz in HS mode per datasheet specifications.
Does the R5F10367ASM#35 include data flash memory, and what are the implications for firmware updates?
No, the R5F10367ASM#35 does not include data flash memory - this feature is exclusive to the R5F102-series variants. As a result, the R5F10367ASM#35 cannot perform in-application programming of non-volatile parameter storage, limiting it to code flash-only updates. Firmware updates require full reprogramming of the 2 KB code flash, and runtime parameter retention must use external EEPROM or battery-backed RAM.
How many analog input channels does the R5F10367ASM#35 support, and what reference options are available?
The R5F10367ASM#35 supports 11 analog input channels (ANI0–ANI3, ANI16–ANI22) with 10-bit resolution. It provides an internal 1.45 V reference voltage and supports external references via AVREFP and AVREFM pins. The device also integrates a temperature sensor, enabling self-calibration and ambient monitoring without external components - all accessible within the R5F10367ASM#35's single-chip solution.
What serial communication interfaces are integrated into the R5F10367ASM#35, and how are they configured?
The R5F10367ASM#35 integrates one UART channel (UART0), one simplified SPI (CSI00), and no simplified I²C - distinguishing it from R5F102-series parts. These interfaces share pins with GPIO and timers and are configured via the Peripheral I/O Redirection Register (PIOR). UART0 supports full-duplex communication at standard baud rates; CSI00 operates in master/slave mode with configurable clock polarity and phase - all managed within the R5F10367ASM#35's unified peripheral framework.
Is the R5F10367ASM#35 pin-compatible with other RL78/G12 devices in TSSOP20 packaging?
Yes, the R5F10367ASM#35 is pin-compatible with all RL78/G12 20-pin TSSOP variants including R5F1026xASM#35 and R5F1036xASM#35, sharing identical pinout, electrical characteristics, and mechanical footprint. However, functional differences exist - e.g., R5F1026x includes data flash and DMA, while R5F1036x (including R5F10367ASM#35) omits them. PCB design can reuse the same layout, but firmware must account for peripheral availability in the R5F10367ASM#35.
