Product details
Overview
R5F101FHAFP#V0 from Renesas is a 44-pin LQFP-packaged RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F101FHAFP#V0 datasheet, R5F101FHAFP#V0 pinout, R5F101FHAFP#V0 application, or R5F101FHAFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8mm package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, and CSI interfaces.
Technical Context
The R5F101FHAFP#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting variable instruction execution time (0.03125 μs @32 MHz to 30.5 μs @32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), real-time clock with calendar/alarm, and hardware multiplier/divider.

FAQ
What is the flash memory configuration of the R5F101FHAFP#V0?
The R5F101FHAFP#V0 contains 96 KB of on-chip code flash memory organized in 1 KB blocks, with no integrated data flash memory - consistent with the R5F101x series designation indicating "data flash not provided." This configuration supports firmware storage and execution but requires external non-volatile memory for parameter logging or field updates unless implemented via code flash wear-leveling techniques.
Does the R5F101FHAFP#V0 support hardware debugging?
Yes, the R5F101FHAFP#V0 includes an on-chip debug interface compliant with Renesas' single-wire debug (SWD) protocol. It supports full break-point, watchpoint, and memory inspection capabilities using standard E2 emulator or compatible debug probes - eliminating the need for dedicated JTAG headers and simplifying PCB layout for production and development.
What is the maximum ADC resolution and channel count supported by the R5F101FHAFP#V0?
The R5F101FHAFP#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports internal reference voltage (1.45 V) and on-die temperature sensor - both accessible only in HS (high-speed main) mode - enabling accurate ratiometric measurements and thermal compensation without external components.
Is the R5F101FHAFP#V0 pin-compatible with other RL78/G13 devices in 44-pin LQFP packages?
Yes, the R5F101FHAFP#V0 shares identical pinout and package dimensions (44-pin LQFP, 10 × 10 mm, 0.8-mm pitch) with all other RL78/G13 devices in the PLQP0044GC-A package variant, including R5F100x and R5F101x series. Functional pin assignments (e.g., P10/SCK00/SCL00) are consistent across the family, enabling hardware reuse across flash/RAM variants.
What industrial temperature range does the R5F101FHAFP#V0 support?
The R5F101FHAFP#V0 is rated for industrial operation from –40°C to +85°C, indicated by the 'D' suffix in its part numbering convention per Renesas' RL78/G13 documentation. This makes it suitable for deployment in factory automation, outdoor metering, and commercial HVAC systems without derating or additional thermal management.
