Product details
Overview
R5F10379ANA#45 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 operates from 1.8 V to 5.5 V, delivers 31 DMIPS at 24 MHz, integrates 12 KB code flash, 768 B RAM, and features an 8/10-bit 11-channel A/D converter, UART, CSI, and 4-channel 16-bit timer - deployed in smart home sensors and battery-powered IoT endpoints.
For engineers reviewing the R5F10379ANA#45 datasheet, R5F10379ANA#45 pinout, R5F10379ANA#45 application, or R5F10379ANA#45 equivalent, this page provides verified technical context, package mapping, functional pin roles, real-world use cases, and validated alternative options - all grounded in Renesas' official R01DS0193EJ0250 Rev.2.50 specification.
Technical Context
The R5F10379ANA#45 implements the RL78 CPU core with 3-stage CISC pipeline, supporting instruction execution times from 0.04167 µs (24 MHz on-chip oscillator) to 1 µs (1 MHz). Its memory subsystem includes 12 KB code flash (1 KB block size), no data flash, and 768 B RAM - distinguishing it from R5F1027x variants which include 2 KB data flash and CRC/SFR guard functions.
It supports single-supply operation (1.8–5.5 V), high-speed on-chip oscillator accuracy of ±5.0% over –40°C to +85°C, and peripheral sets limited to 1 UART, 1 CSI, and no simplified I²C - consistent with R5F1037x family constraints. Power modes include HALT, STOP, and SNOOZE, enabling sub-63 μA/MHz active current draw.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10279ANA#45 | Includes 2 KB data flash, CRC/SFR guard, ±1.0% oscillator accuracy, and DMA - adds 2 KB nonvolatile data logging capability. | Suitable for firmware requiring field-upgradable calibration tables or secure boot parameters. | Select when persistent parameter storage or enhanced safety features are required; otherwise R5F10379ANA#45 offers lower cost and identical footprint. |
| R5F10378ANA#45 | Same package and pinout, but with 8 KB code flash and 512 B RAM - reduces memory headroom for larger firmware images. | Better suited for cost-optimized designs where feature set matches but code size stays under 8 KB. | Choose for legacy firmware porting or budget-constrained production; verify RAM usage does not exceed 512 B in stack/heap allocation. |
Compared with R5F10279ANA#45, the R5F10379ANA#45 omits data flash and safety features to reduce cost and power, while retaining identical packaging and core peripherals; versus R5F10378ANA#45, it provides +4 KB flash and +256 B RAM for more complex control algorithms without changing PCB layout.

FAQ
What is the maximum operating frequency and oscillator accuracy of the R5F10379ANA#45?
The R5F10379ANA#45 supports up to 24 MHz operation using its high-speed on-chip oscillator, with accuracy specified at ±5.0% over the full –40°C to +85°C temperature range and 1.8 V to 5.5 V supply. This eliminates the need for external crystals in many applications while maintaining sufficient timing margin for UART and timer-based functions. The R5F10379ANA#45 does not support external crystal oscillation above 20 MHz.
Does the R5F10379ANA#45 include data flash memory?
No, the R5F10379ANA#45 does not include data flash memory. As confirmed in Renesas' R01DS0193EJ0250 Rev.2.50 documentation, R5F103x-series devices omit the 2 KB data flash present in R5F102x variants. All nonvolatile storage is handled through the 12 KB code flash, which supports self-programming but lacks background operation capability. This design choice reduces cost and power consumption for applications that do not require frequent parameter updates.
How many analog input channels does the R5F10379ANA#45 support, and what reference options are available?
The R5F10379ANA#45 supports 11 analog input channels (ANI0–ANI3, ANI16–ANI22) with 8/10-bit resolution. It provides an internal 1.45 V reference voltage and supports ratiometric measurements using AVREFP and AVREFM pins. External reference voltages are not supported - the A/D converter operates exclusively with the internal reference or supply-ratiometric mode, simplifying analog front-end design for sensor interfacing.
What serial communication interfaces are available on the R5F10379ANA#45?
The R5F10379ANA#45 integrates one UART channel, one CSI (Simplified SPI) channel, and no simplified I²C interface - consistent with R5F1037x family specifications. It does support hardware I²C via SCLA0/SDAA0 pins (remappable from P60/P61), but this requires software configuration and lacks dedicated I²C peripheral logic. For pure I²C master functionality, R5F10279ANA#45 is recommended instead.
What is the RAM capacity and package type of the R5F10379ANA#45?
The R5F10379ANA#45 contains 768 bytes of on-chip RAM and is packaged in a 24-pin HWQFN (4 mm × 4 mm, 0.5 mm pitch) with exposed die pad. This package matches the PWQN0024KE-A / PWQN0024KF-A mechanical outline and requires connection of the exposed pad to VSS for optimal thermal performance and EMI suppression. The RAM size supports moderate real-time control stacks and sensor data buffering without external memory.
