Product details
Overview
R5F10379ANA#W0 from Renesas Electronics is a 24-pin HWQFN-packaged RL78/G12 16-bit microcontroller designed for ultra-low-power embedded control in consumer and industrial applications. It features 12 KB code flash, 768 B RAM, 10-bit 11-channel ADC, 4-channel 16-bit TAU timer, UART/CSI00 serial interfaces, and operates from 1.8 V to 5.5 V with true low-power consumption (63 μA/MHz) - enabling battery-powered sensor nodes and smart home controllers.
For engineers reviewing the R5F10379ANA#W0 datasheet, R5F10379ANA#W0 pinout, R5F10379ANA#W0 application, or R5F10379ANA#W0 equivalent, this page delivers verified technical context, exact package mapping (HWQFN-24, 4 × 4 mm, 0.5-mm pitch), confirmed peripheral configuration (no data flash, no DMA, no simplified I²C), and real-world use-case guidance for cost-sensitive, power-constrained MCU selection.
Technical Context
The R5F10379ANA#W0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 31 DMIPS at 24 MHz using its high-accuracy ±5.0% on-chip oscillator (–40°C to +85°C). Its memory subsystem includes 12 KB code flash (1 KB block size), 768 B RAM, and no data flash - distinguishing it from R5F102x variants.
Peripheral integration centers on single-channel UART0, single-channel CSI00 (SPI-compatible), 11-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and four 16-bit timer channels supporting PWM output. Power management includes HALT, STOP, and SNOOZE modes, POR, and 12-level LVD with interrupt/reset capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10279ANA#W0 | Includes 2 KB data flash, ±1.0% oscillator accuracy, DMA, CRC, RAM guard, and simplified I²C - higher BOM cost and larger code footprint | Suitable for firmware-over-the-air updates and safety-critical checksum validation where R5F10379ANA#W0 lacks data flash and CRC | Select when field firmware updates or functional safety compliance (IEC 61508 SIL-2) require non-volatile parameter storage and hardware CRC |
| R5F10378ANA#W0 | Same package and pinout; reduced 8 KB code flash and 512 B RAM - identical peripheral set and power profile | Better fit for simpler firmware (e.g., single-button remote) where 12 KB flash is over-provisioned | Choose for cost-optimized designs with <64 KB instruction footprint and no future feature expansion planned |
Compared with R5F10279ANA#W0, the R5F10379ANA#W0 trades data flash, DMA, and tighter oscillator tolerance for lower unit cost and smaller memory footprint; versus R5F10378ANA#W0, it provides +4 KB flash and +256 B RAM for added feature headroom without changing PCB layout or firmware architecture.

FAQ
What is the maximum operating frequency and instruction throughput of the R5F10379ANA#W0?
The R5F10379ANA#W0 achieves a maximum system clock of 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. Its minimum instruction execution time is 0.04167 µs at 24 MHz, enabled by the RL78 CPU's 3-stage pipeline. External crystal operation supports up to 20 MHz in HS mode (VDD ≥ 2.7 V) or 8 MHz in LS mode (VDD ≥ 1.8 V). The R5F10379ANA#W0 does not support overclocking beyond these limits.
Does the R5F10379ANA#W0 include data flash memory?
No, the R5F10379ANA#W0 does not include data flash memory. Per Renesas documentation, R5F103x-series devices omit the 2 KB data flash found in R5F102x variants. All non-volatile parameter storage must be implemented in the 12 KB code flash using self-programming routines - requiring careful sector management and wear-leveling in firmware. This design reduces cost and simplifies qualification for consumer-grade applications.
What serial communication interfaces are available on the R5F10379ANA#W0?
The R5F10379ANA#W0 provides one UART channel (RxD0/TxD0) and one CSI00 channel (SCK00/SI00/SO00), which is SPI-compatible. It does not include I²C hardware - simplified I²C (IIC00/IIC01) and second CSI channel (CSI01) are exclusive to R5F102x devices. UART and CSI share pins P10–P12, allowing flexible routing but requiring software configuration to avoid conflict.
What is the ADC configuration of the R5F10379ANA#W0?
The R5F10379ANA#W0 integrates a 10-bit successive-approximation ADC with 11 input channels (ANI0–ANI3, ANI16–ANI22), internal 1.45 V reference voltage, and an integrated temperature sensor. Input voltage range is 0 V to AVREFP (typically VDD), with absolute max rating of –0.3 V to VDD + 0.3 V. Conversion time is 1.1 µs per sample at 24 MHz system clock, supporting up to 909 kSPS aggregate throughput across all channels.
What power-saving modes does the R5F10379ANA#W0 support, and what are their typical current draws?
The R5F10379ANA#W0 supports HALT (0.52 μA), STOP (0.42 μA), and SNOOZE modes - all retaining RAM content and selected peripheral states. HALT stops the CPU while keeping peripherals active; STOP halts both CPU and most peripherals; SNOOZE allows ADC or serial interface to operate autonomously during low-power sleep. All values measured at VDD = 3.0 V, TA = 25°C, with LVD disabled and no external load.
