Product details
Overview
R5F101GFANA#W0 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB RAM, and no data flash memory, operating at 1.6–5.5 V and delivering 41 DMIPS at 32 MHz for ultra-low-power industrial control applications including motor drive supervision and sensor-based HVAC subsystems.
For engineers reviewing the R5F101GFANA#W0 datasheet, R5F101GFANA#W0 pinout, R5F101GFANA#W0 application, or R5F101GFANA#W0 equivalent, key selection criteria include its 128 KB code flash capacity, absence of on-chip data flash, 48-pin HWQFN (7 × 7 mm, 0.5-mm pitch) package, -40°C to +105°C industrial temperature grade (G), and support for real-time clock, 10-bit ADC (26 channels), and multiple serial interfaces (CSI, UART/LIN, I²C).
Technical Context
The R5F101GFANA#W0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, real-time clock with calendar/alarm functions, and watchdog timer powered by a dedicated low-speed on-chip oscillator.
Its peripheral set includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 16-bit timers (12 channels), DMA controller (4 channels), and serial interfaces: CSI (up to 8 channels), UART/LIN (up to 4 channels), and I²C/Simplified I²C (up to 10 channels), all configurable for mixed-voltage I/O (1.8/2.5/3.0 V interface capability).
