Product details
Overview
R5F10379ANA#65 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, 1.8–5.5 V operation, 24 MHz high-speed on-chip oscillator (±5% accuracy), and 8-channel 10-bit A/D converter with 11 analog inputs. It executes at 31 DMIPS and supports HALT/STOP/SNOOZE low-power modes for battery-powered sensor nodes and smart peripherals.
For engineers reviewing the R5F10379ANA#65 datasheet, R5F10379ANA#65 pinout, R5F10379ANA#65 application, or R5F10379ANA#65 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, no DMA or CRC hardware, and ±5% oscillator tolerance over –40 to +85°C - critical for timing-sensitive but cost-optimized control designs.
Technical Context
The R5F10379ANA#65 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and 8-bit register banks. Its clock system integrates a high-speed on-chip oscillator (selectable 1–24 MHz) and low-speed 15 kHz oscillator, enabling dynamic mode switching between active and ultra-low-power states.
Peripheral integration includes one 16-bit timer array (TAU0) with 4 channels, one watchdog timer, one 12-bit interval timer, simplified SPI (CSI00), UART0, and I²C-compatible IICA0 interface. All analog functions - including AVREFP/AVREFM references and ANI0–ANI3/ANI16–ANI22 inputs - are routed through dedicated pins with internal reference voltage (1.45 V) and temperature sensor support.

FAQ
What is the maximum operating frequency and instruction throughput of the R5F10379ANA#65?
The R5F10379ANA#65 operates at up to 24 MHz using its high-speed on-chip oscillator and delivers 31 DMIPS (Dhrystone MIPS) performance. Its RL78 CPU core achieves a minimum instruction execution time of 0.04167 µs at 24 MHz, supporting real-time control loops and responsive user interfaces without external clock components.
Does the R5F10379ANA#65 include data flash memory?
No, the R5F10379ANA#65 does not include data flash memory. As confirmed in Renesas documentation (Section 1.3.1), R5F103-series devices omit the 2 KB data flash present in R5F102-series counterparts like R5F10279ANA#65. Firmware must rely on external EEPROM or code flash emulation for non-volatile parameter storage.
What are the low-power modes supported by the R5F10379ANA#65 and their typical current consumption?
The R5F10379ANA#65 supports HALT, STOP, and SNOOZE modes. HALT stops the CPU while keeping peripherals active (~1.2 µA typical); STOP halts all clocks (<0.5 µA); SNOOZE allows UART or CSI wake-up with background operation. Active-mode current is 63 μA/MHz, enabling multi-year battery life in intermittent-sensing applications.
Which serial interfaces are available on the R5F10379ANA#65?
The R5F10379ANA#65 provides one UART channel (UART0), one simplified SPI interface (CSI00), and one I²C-compatible interface (IICA0). It does not include simplified I²C (IIC00/IIC01) or additional UART/CSI channels found in R5F1027x variants - limiting it to single-host communication plus one peripheral bus.
What is the analog input capability of the R5F10379ANA#65?
The R5F10379ANA#65 integrates an 8/10-bit resolution A/D converter with 11 input channels (ANI0–ANI3, ANI16–ANI22), internal 1.45 V reference voltage, and an on-die temperature sensor. Input voltage range is 0 to VDD or 0 to AVREF(+), supporting direct sensing of thermistors, potentiometers, and battery voltages across its 1.8–5.5 V supply range.
