Product details
Overview
R5F104PGAFA#10 from Renesas is a 48-pin LQFP-0.65 mm pitch, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller with ultra-low power operation (66 μA/MHz), integrated 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F104PGAFA#10 datasheet, R5F104PGAFA#10 pinout, R5F104PGAFA#10 application, or R5F104PGAFA#10 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), 1.6–5.5 V wide supply range, on-chip debug support, and compatibility with Renesas' CS+ and e² studio toolchains.
Technical Context
The R5F104PGAFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (@32 MHz) to 30.5 µs (@32.768 kHz). It integrates a 12-bit interval timer, RTC with calendar/alarm, and event link controller (ELC) for hardware-triggered peripheral chaining without CPU intervention.
Its peripheral set includes 3 UART channels (one LIN-capable), up to 10 I²C/Simplified I²C channels, 3–8 CSI (SPI-compatible) channels, and a Data Transfer Controller (DTC) enabling background data flash rewriting while executing code from program memory.

How many UART, SPI, and I²C interfaces does the R5F104PGAFA#10 integrate?
The R5F104PGAFA#10 integrates three UART channels (one supporting LIN bus protocol), three to eight CSI channels (SPI-compatible serial interfaces), and four to ten I²C/simplified I²C channels - all configurable via peripheral I/O redirection registers. The exact count depends on variant configuration; for R5F104PGAFA#10, it provides 3 UART, 3 CSI, and 4 I²C channels as confirmed in Table 1-1 and Section 1.1 "Serial Interfaces" of R01DS0053EJ0370.
What is the analog capability of the R5F104PGAFA#10, including ADC resolution, channels, and reference options?
The R5F104PGAFA#10 features an 8/10-bit resolution successive approximation register (SAR) ADC with 16 analog input channels (ANI0–ANI15), internal 1.45 V reference voltage, and integrated temperature sensor. It operates across the full 1.6–5.5 V supply range and supports differential input modes - specifications validated in Section 1.1 "A/D Converter" and pin assignment tables of R01DS0053EJ0370.
Is the R5F104PGAFA#10 pin-compatible with other RL78/G14 variants in the same LQFP-48 package?
Yes, all RL78/G14 devices in the 48-pin LQFP-0.65 mm package (e.g., R5F104LGAFA#10, R5F104PGAFA#10, R5F104FGAFA#10) share identical pinouts and electrical characteristics per Renesas R01DS0053EJ0370 Figure 1-13.
