Product details
Overview
R5F10367ASM#55 from Renesas Electronics is a 20-pin RL78/G12 16-bit microcontroller designed for ultra-low-power embedded control in consumer-grade applications (–40°C to +85°C). It integrates 2 KB code flash, 256 B RAM, 10-bit A/D converter with 11 input channels, and operates from 1.8 V to 5.5 V at up to 24 MHz - delivering 31 DMIPS while consuming only 63 μA/MHz. It serves as the main system controller in battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F10367ASM#55 datasheet, R5F10367ASM#55 pinout, R5F10367ASM#55 application, or R5F10367ASM#55 equivalent, this page provides verified technical context, validated package mapping, confirmed peripheral configuration (1 UART, 1 CSI, no data flash), and real-world design implications for low-voltage, low-power firmware development.
Technical Context
The R5F10367ASM#55 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.04167 μs (24 MHz on-chip oscillator) to 1 μs (1 MHz). Its memory subsystem includes 2 KB of code flash (1 KB block size) with self-programming capability and flash shield window security, but excludes data flash memory - distinguishing it from R5F102-series variants.
Peripherals are optimized for minimal footprint: 4-channel 16-bit TAU timer, 1-channel UART0, 1-channel simplified SPI (CSI00), no DMA or CRC engine, and key interrupt support across 6 pins. The high-speed on-chip oscillator offers ±5.0% accuracy over –40°C to +85°C, and the device supports HALT/STOP/SNOOZE low-power modes with on-chip POR and 12-level LVD.

FAQ
Does R5F10367ASM#55 include data flash memory?
No, the R5F10367ASM#55 does not include data flash memory - this is a defining distinction from the R5F102x series. It contains only 2 KB of code flash memory and 256 B of RAM. Applications requiring non-volatile parameter storage must use external EEPROM or rely on code flash wear-leveling techniques, as confirmed in Section 1.3.1 of the R01DS0193EJ0250 datasheet.
What is the maximum operating frequency and corresponding DMIPS rating for R5F10367ASM#55?
The R5F10367ASM#55 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. This is measured under HS mode with VDD ≥ 2.7 V, as specified in the "Outline" section (Page 1) of the R01DS0193EJ0250 datasheet. At lower voltages (1.8–2.4 V), max frequency drops to 16 MHz.
Which serial interfaces are supported on R5F10367ASM#55, and are they pin-compatible with other RL78/G12 variants?
The R5F10367ASM#55 supports exactly one UART channel (UART0), one simplified SPI (CSI00), and no simplified I²C interface - differing from R5F1026x which includes two CSI and two simplified I²C channels. Pin assignments for UART and CSI are identical across 20-pin TSSOP variants, enabling layout reuse, but I²C functionality requires remapping to P60/P61 if implemented externally.
What low-power modes are available on R5F10367ASM#55, and what are their typical current draws?
The R5F10367ASM#55 supports HALT (63 μA/MHz), STOP (0.52 μA typical), and SNOOZE modes. In STOP mode with RAM retention and watchdog enabled, current draw is 0.52 μA at VDD = 3.0 V and TA = 25°C. These values are measured per Section 2.3.2 of the R01DS0193EJ0250 datasheet and assume proper configuration of clock gating and peripheral disable.
Is R5F10367ASM#55 pin-compatible with R5F10267ASM#55, and what functional differences affect interchangeability?
Yes, the R5F10367ASM#55 is pin-compatible with R5F10267ASM#55 in the 20-pin TSSOP package. However, key functional differences prevent drop-in replacement: R5F10267ASM#55 includes 2 KB data flash, DMA controller, ±1.0% oscillator accuracy, and CRC engine - all absent in R5F10367ASM#55. Firmware relying on data flash writes or DMA transfers will not operate without modification.
