Product details
Overview
R5F10367ASP#55 from Renesas Electronics is a 20-pin LSSOP ultra-low-power 16-bit RL78/G12 microcontroller for consumer-grade embedded control, featuring 2 KB code flash, 256 B RAM, 10-bit 8-channel ADC, 4-channel 16-bit timer, and UART/CSI serial interfaces operating at 1.8–5.5 V supply voltage.
For engineers reviewing the R5F10367ASP#55 datasheet, R5F10367ASP#55 pinout, R5F10367ASP#55 application, or R5F10367ASP#55 equivalent, key selection considerations include its 20-pin LSSOP-20 package, absence of data flash memory, -40°C to +85°C industrial temperature grade (A), and support for high-speed on-chip oscillator up to 24 MHz with ±5.0% accuracy.
Technical Context
The R5F10367ASP#55 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and selectable instruction execution time (0.04167 µs @ 24 MHz). It integrates a 12-bit interval timer, window watchdog timer, on-chip power-on-reset and voltage detector (12-level LVD), and supports HALT/STOP/SNOOZE low-power modes.
Unlike R5F102-series variants, this part omits data flash memory, DMA controller, CRC operation, RAM guard, and SFR guard functions. Its serial interface includes only one UART channel and one simplified SPI (CSI) channel - no I²C capability - and it lacks safety-related peripherals found in higher-grade RL78/G12 members.

FAQ
What is the maximum operating frequency of the R5F10367ASP#55?
The R5F10367ASP#55 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 at VDD ≥ 2.7 V or 8 MHz at VDD = 1.8–2.4 V. The CPU executes instructions at 0.04167 µs minimum cycle time under 24 MHz operation, delivering 31 DMIPS performance.
Does the R5F10367ASP#55 include data flash memory?
No, the R5F10367ASP#55 does not include data flash memory. As confirmed in the RL78/G12 datasheet Section 1.3.1, R5F103-series products omit the 2 KB data flash present in R5F102-series variants. This simplifies firmware design for applications that store parameters in external EEPROM or do not require non-volatile data retention beyond code flash.
What serial communication interfaces are supported by the R5F10367ASP#55?
The R5F10367ASP#55 supports one UART channel and one simplified SPI (CSI) channel. It does not include I²C hardware - unlike some R5F102 variants - and lacks DMA-assisted transfers. Both UART and CSI share pins with GPIO and analog inputs, requiring register configuration to assign functionality, and operate within the 1.8–5.5 V supply range without external level shifting.
What is the operating temperature range for the R5F10367ASP#55?
The R5F10367ASP#55 is rated for operation from -40°C to +85°C, corresponding to the "A" (consumer/industrial) grade designation in its part number. This range satisfies requirements for indoor consumer electronics, residential appliances, and many industrial control environments where extended high-temperature operation is not required.
Can the R5F10367ASP#55 drive LEDs or small relays directly from its I/O pins?
Yes, selected I/O pins on the R5F10367ASP#55 can sink up to 40 mA or source up to 40 mA per pin (excluding P20–P23), with total package sink/source limits of 170 mA. This allows direct driving of standard LEDs or small signal relays without external transistors, though thermal derating and voltage drop must be verified per application. P20–P23 are limited to 1 mA sink/0.5 mA source and are intended for analog sensing.
