Product details
Overview
R5F10369ASM#15 from Renesas Electronics is a 20-pin RL78/G12 16-bit microcontroller designed for ultra-low-power general-purpose embedded control, featuring 12 KB code flash, 768 B RAM, 1.8–5.5 V operation, and 31 DMIPS at 24 MHz - deployed in battery-powered sensor nodes and industrial HMI panels.
For engineers reviewing the R5F10369ASM#15 datasheet, R5F10369ASM#15 pinout, R5F10369ASM#15 application, or R5F10369ASM#15 equivalent, key selection criteria include its TSSOP-20 package, absence of data flash memory, single UART channel, 10-bit 11-channel ADC, and -40°C to +85°C industrial-grade temperature range.
Technical Context
The R5F10369ASM#15 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and selectable high-speed on-chip oscillator (1–24 MHz, ±5% accuracy over –40°C to +85°C). It supports HALT/STOP/SNOOZE low-power modes and executes instructions in as little as 0.04167 µs at 24 MHz.
It integrates a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, four 16-bit timer channels (including PWM-capable outputs), watchdog timer, and on-chip power-on-reset and voltage detector with 12-level interrupt/reset selection - all without DMA or data flash support.

FAQ
What is the maximum operating frequency of the R5F10369ASM#15?
The R5F10369ASM#15 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator. At this speed, it delivers 31 DMIPS performance. External crystal operation is limited to 20 MHz (1.8–5.5 V) or 16 MHz (1.8–2.4 V), and the device maintains full functionality across its 1.8–5.5 V supply range.
Does the R5F10369ASM#15 include data flash memory?
No, the R5F10369ASM#15 does not include data flash memory. This is a defining distinction from the R5F102xx series. The R5F10369ASM#15 provides 12 KB of code flash only, with no dedicated data flash area - all nonvolatile parameter storage must be implemented in code flash sectors or external EEPROM/FRAM.
What serial communication interfaces are supported by the R5F10369ASM#15?
The R5F10369ASM#15 supports one UART channel, one simplified SPI (CSI) channel, and zero simplified I²C channels. It does not implement simplified I²C or additional UART/CSI instances - unlike the R5F102xx series, which offers two CSI and two simplified I²C channels in 20-pin variants.
What is the ADC resolution and channel count on the R5F10369ASM#15?
The R5F10369ASM#15 integrates an 8/10-bit resolution successive-approximation ADC with 11 input channels (ANI0–ANI3, ANI16–ANI22). It includes an internal 1.45 V reference voltage and an on-chip temperature sensor, enabling self-referenced analog measurements without external components.
Is the R5F10369ASM#15 pin-compatible with other RL78/G12 20-pin devices?
Yes, the R5F10369ASM#15 shares the identical 20-pin TSSOP (PTSP0020JI-A) package and pinout with all other RL78/G12 20-pin variants, including R5F1026x, R5F1036x, and R5F10368ASM#15. Functional differences (e.g., data flash presence, oscillator accuracy, peripheral count) do not affect physical compatibility or PCB layout.
