Product details
Overview
R5F10379ANA#U0 from Renesas Electronics is a 24-pin HWQFN-packaged RL78/G12 16-bit MCU designed for ultra-low-power embedded control in consumer and industrial applications. It delivers 31 DMIPS at 24 MHz, features 12 KB code flash, 768 B RAM, operates from 1.8–5.5 V, and supports HALT/STOP/SNOOZE power modes for battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F10379ANA#U0 datasheet, R5F10379ANA#U0 pinout, R5F10379ANA#U0 application, or R5F10379ANA#U0 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.5-mm pitch) footprint, absence of data flash memory, single UART channel, and -40°C to +85°C operating range for cost-sensitive, low-complexity control tasks.
Technical Context
The R5F10379ANA#U0 implements the RL78 CPU core with a 3-stage CISC pipeline, 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% (TA = –40 to +85°C) high-speed on-chip oscillator selectable from 1–24 MHz and a 15 kHz low-speed on-chip oscillator for watchdog and interval timing.
Peripheral integration includes a 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 simplified serial interfaces: one UART, one CSI (SPI-compatible), and no I²C support - consistent with the R5F103 product line's reduced peripheral set versus R5F102 variants.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F10379ANA#U0?
The R5F10379ANA#U0 achieves a maximum operating frequency of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS of processing performance. This speed is validated across the full 1.8–5.5 V supply range and -40°C to +85°C ambient temperature, enabling responsive real-time control in battery-powered and mains-operated systems without external crystal dependency.
Does the R5F10379ANA#U0 include data flash memory?
No, the R5F10379ANA#U0 does not include data flash memory. As confirmed in the RL78/G12 datasheet Section 1.3.1, R5F103-series devices omit the 2 KB data flash present in R5F102 variants. Firmware must store configuration or logging data in external EEPROM or utilize code flash with self-programming libraries - a deliberate trade-off for lower cost and simplified memory management in fixed-function applications.
What are the supported serial communication interfaces on the R5F10379ANA#U0?
The R5F10379ANA#U0 supports one UART channel (RxD0/TxD0), one simplified SPI (CSI) channel (SCK00/SI00/SO00), and zero I²C channels. This peripheral set aligns with the R5F103 product family specification and differs from R5F102 devices, which offer additional CSI and simplified I²C channels. The single UART suffices for host communication, while CSI enables sensor or display interfacing.
What power-saving modes are available on the R5F10379ANA#U0 and their typical current draw?
The R5F10379ANA#U0 supports HALT mode (63 μA/MHz), STOP mode (0.23 μA), and SNOOZE mode (fast wake-up from low-power sleep). These modes are fully documented in the RL78/G12 datasheet Section 1.1 and enable aggressive energy optimization - for example, STOP mode draws less than 0.3 μA, making it ideal for multi-year battery operation in wireless sensor endpoints.
Is the R5F10379ANA#U0 pin-compatible with other RL78/G12 24-pin variants?
Yes, the R5F10379ANA#U0 shares identical pinout and package (24-pin HWQFN, 4 × 4 mm, 0.5-mm pitch) with all other R5F1037x and R5F1027x variants in the RL78/G12 family, including R5F10279ANA#U0 and R5F10378ANA#U0. Pin functions match per the 24-pin top view diagram in datasheet Section 1.4.2, enabling drop-in replacement within the same R5F103/R5F1027 subgroup when memory or peripheral requirements change.
