Product details
Overview
R5F10379ANA#25 from Renesas Electronics is a 24-pin HWQFN-packaged 16-bit RL78/G12 microcontroller designed for ultra-low-power embedded control in consumer-grade applications (–40°C to +85°C). It features 12 KB code flash, 768 B RAM, 10-bit 8-channel ADC, 4-channel 16-bit TAU timer, and single UART interface - optimized for battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F10379ANA#25 datasheet, R5F10379ANA#25 pinout, R5F10379ANA#25 application, or R5F10379ANA#25 equivalent, key selection criteria include its 1.8–5.5 V operation range, absence of data flash memory, 5.0% high-speed on-chip oscillator accuracy over –40°C to +85°C, and lack of DMA or safety functions compared to R5F102 variants.
Technical Context
The R5F10379ANA#25 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It supports HALT/STOP/SNOOZE low-power modes and executes instructions at 0.04167 µs minimum (24 MHz on-chip oscillator), delivering 31 DMIPS at 24 MHz.
Its peripheral set includes one UART channel, one simplified SPI (CSI) channel, no simplified I²C, 8-channel 10-bit ADC with internal reference, and programmable clock/buzzer output. The device lacks data flash, DMA, CRC, RAM guard, and SFR guard - distinguishing it from R5F1027x counterparts.

FAQ
What is the maximum operating frequency of the R5F10379ANA#25?
The R5F10379ANA#25 supports a maximum system clock frequency of 24 MHz using its high-speed on-chip oscillator. When using an external crystal (X1/X2), the maximum main system clock is 20 MHz at VDD ≥ 2.7 V or 16 MHz at VDD ≥ 2.4 V. Instruction execution time is as fast as 0.04167 µs at 24 MHz, delivering 31 DMIPS performance. The R5F10379ANA#25 does not support overclocking beyond these rated frequencies.
Does the R5F10379ANA#25 include data flash memory?
No, the R5F10379ANA#25 does not include data flash memory. This is a defining distinction from the R5F1027x series, which integrates 2 KB of data flash. The R5F10379ANA#25 relies solely on its 12 KB code flash for both program storage and non-volatile parameter storage, requiring software-managed wear leveling if EEPROM-like functionality is needed. This omission reduces cost and simplifies qualification for applications without field update requirements.
What are the low-power modes supported by the R5F10379ANA#25?
The R5F10379ANA#25 supports HALT, STOP, and SNOOZE low-power modes. HALT stops the CPU while preserving RAM and peripheral registers; STOP disables the main clock and reduces current to ~0.52 µA; SNOOZE allows selected peripherals (e.g., UART, ADC) to operate autonomously while the CPU sleeps. All modes retain SRAM contents and support wake-up via external interrupt, timer, or serial activity - enabling sub-µA average power in duty-cycled sensor applications.
Can the R5F10379ANA#25 drive standard LEDs directly?
Yes, the R5F10379ANA#25 can drive standard LEDs directly using its 22 GPIOs, including five N-ch open-drain outputs rated for VDD-tolerant operation (up to 5.5 V). Each pin supports up to 40 mA sink current (100 mA total for designated port groups), sufficient for common 20 mA indicator LEDs. For higher-current loads like RGB LEDs or relays, external drivers are recommended. The integrated programmable clock/buzzer output also supports LED blinking without CPU intervention.
Is the R5F10379ANA#25 pin-compatible with other RL78/G12 devices in HWQFN-24 package?
Yes, the R5F10379ANA#25 shares identical pinout and package (HWQFN-24, PWQN0024KF-A) with all other R5F1027x and R5F1037x variants in the same pin count, including R5F10279ANA#25 and R5F10378ANA#25. Peripheral function allocation is consistent across the family, though feature availability (e.g., data flash, DMA, oscillator accuracy) differs. This enables hardware reuse across firmware variants and simplifies migration paths within the RL78/G12 portfolio.
