Product details
Overview
R5F10369ASP#X0 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 features 12 KB code flash, 768 B RAM, 1.8–5.5 V operation, 24 MHz max CPU speed (31 DMIPS), and operates across –40°C to +85°C for A-grade applications - deployed in battery-powered sensor nodes and appliance control panels.
For engineers reviewing the R5F10369ASP#X0 datasheet, R5F10369ASP#X0 pinout, R5F10369ASP#X0 application, or R5F10369ASP#X0 equivalent, key selection criteria include its 1-channel UART + 1-channel CSI interface count, absence of data flash memory, lack of DMA and CRC hardware, and precise 20-pin LSSOP-0.65mm package compatibility with space-constrained PCB layouts.
Technical Context
The R5F10369ASP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.04167 µs (@24 MHz high-speed on-chip oscillator) to 1 µs (@1 MHz). Its clock system integrates a high-accuracy ±5.0% (–40°C to +85°C) programmable on-chip oscillator (1–24 MHz) and supports external crystal (1–20 MHz) via X1/X2 pins.
Peripheral integration includes an 8/10-bit 11-channel A/D converter with internal 1.45 V reference and temperature sensor, four 16-bit timer channels with PWM capability, one watchdog timer, and a 12-bit interval timer - all operating under true low-power modes (HALT, STOP, SNOOZE) achieving 63 µA/MHz active current consumption.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F10369ASP#X0?
The R5F10369ASP#X0 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. This is measured under standard conditions (VDD = 2.7–5.5 V, TA = –40°C to +85°C) and reflects integer computational throughput - sufficient for real-time motor control, sensor fusion, and protocol stack execution in resource-constrained systems.
Does the R5F10369ASP#X0 include data flash memory, and how does that affect firmware update capability?
No, the R5F10369ASP#X0 does not include data flash memory - unlike R5F102xx variants which integrate 2 KB. This means firmware updates must be performed entirely within code flash using self-programming libraries, requiring careful partitioning of flash sectors and additional RAM overhead. The R5F10369ASP#X0 is intended for fixed-function applications where field updates are not required.
Which serial communication interfaces are available on the R5F10369ASP#X0, and how many channels does each support?
The R5F10369ASP#X0 provides one UART channel (RxD0/TxD0), one Simplified SPI (CSI) channel (SCK00/SI00/SO00), and one Simplified I²C (SCL00/SDA00) channel - all mapped to P10–P12 by default. Unlike R5F1026x variants, it lacks second CSI/I²C channels and DMA-assisted transfers, limiting multi-peripheral concurrency but simplifying driver development.
What are the key low-power features of the R5F10369ASP#X0, and what is its typical active current consumption?
The R5F10369ASP#X0 supports HALT, STOP, and SNOOZE low-power modes with wake-up times under 1 µs. Its active current consumption is rated at 63 µA/MHz at 24 MHz, translating to ~1.5 mA total at full speed - enabling multi-year battery life in periodic-sampling applications. These modes are controlled via dedicated system registers and require no external components.
Is the R5F10369ASP#X0 pin-compatible with other RL78/G12 20-pin variants, and what package type does it use?
Yes, the R5F10369ASP#X0 uses the 20-pin plastic LSSOP (4.4 × 6.5 mm, 0.65-mm pitch) package - identical to R5F1026x, R5F1036x, and R5F1027x 20-pin variants. Pin mapping is fully compatible across this group, allowing drop-in replacement between R5F1036x parts (e.g., R5F10368ASP#X0 → R5F10369ASP#X0) without PCB changes, provided peripheral configuration matches.
