Product details
Overview
R5F10279ANA#65 from Renesas Electronics is a 24-pin HWQFN-packaged RL78/G12 16-bit microcontroller with 12 KB code flash, 2 KB data flash, 1.5 KB RAM, and ultra-low-power operation (63 μA/MHz). It integrates a 10-bit 11-channel ADC, dual CSI/I²C serial interfaces, UART, 4-channel 16-bit TAU timer, DMA controller, and operates across 1.8–5.5 V at –40°C to +85°C for consumer-grade embedded control.
For engineers reviewing the R5F10279ANA#65 datasheet, R5F10279ANA#65 pinout, R5F10279ANA#65 application, or R5F10279ANA#65 equivalent, this page delivers 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 R5F10279ANA#65 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.04167 μs (@24 MHz high-speed on-chip oscillator) to 1 μs (@1 MHz). Its memory subsystem includes 12 KB code flash (1 KB block size), 2 KB data flash with background operation (BGO) and 1M rewrite cycles, and 1.5 KB on-chip RAM.
Peripherals include two CSI channels (SPI-compatible), two simplified I²C channels, one UART channel, four 16-bit timer channels with PWM capability, a 12-bit interval timer, window watchdog timer, CRC engine, and key interrupt support. Power management features HALT, STOP, and SNOOZE modes, on-chip POR/LVD, and ±1.0% high-speed oscillator accuracy over –20°C to +85°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10278ANA#65 | 8 KB code flash, same 2 KB data flash, identical peripherals and package. | Reduced firmware capacity limits complex protocol stacks or large UI assets. | Select when application firmware fits within 8 KB and cost optimization is prioritized over future scalability. |
| R5F10379ANA#65 | No data flash; lacks DMA, CRC, RAM guard, and simplified I²C; ±5.0% oscillator accuracy. | Unsuited for field-updatable devices or safety-critical logging; higher timing uncertainty affects time-triggered protocols. | Choose only for fixed-function, low-cost applications where data persistence and peripheral richness are unnecessary. |
Compared with R5F10279ANA#65, R5F10278ANA#65 trades flash capacity for lower unit cost while retaining full peripheral compatibility, whereas R5F10379ANA#65 sacrifices data flash, DMA, and precision timing - making it unsuitable for applications requiring firmware updates or deterministic real-time response.
