Product details
Overview
R5F101JHAFA#V0 from Renesas is a 52-pin LQFP-0.65mm microcontroller in the RL78/G13 family, featuring 128 KB flash memory, 12 KB RAM, and no data flash. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101JHAFA#V0 datasheet, R5F101JHAFA#V0 pinout, R5F101JHAFA#V0 application, or R5F101JHAFA#V0 equivalent, key selection criteria include its 52-pin LQFP package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and integrated 10-bit ADC with 26 analog inputs.
Technical Context
The R5F101JHAFA#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer using a dedicated low-speed oscillator.
Peripheral integration includes up to 26-channel 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timer, 2–4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable without external components.

FAQ
Does R5F101JHAFA#V0 include on-chip data flash memory?
No, R5F101JHAFA#V0 does not include data flash memory. The "101" in the part number explicitly indicates data flash is omitted per Renesas' RL78/G13 naming convention. Applications requiring non-volatile parameter storage must use external EEPROM or utilize code flash with wear-leveling firmware. R5F101JHAFA#V0 retains full code flash functionality including self-programming and boot swap.
What is the operating temperature range for R5F101JHAFA#V0?
R5F101JHAFA#V0 is rated for industrial operation from -40°C to +85°C. The "D" suffix in the full ordering code (e.g., R5F101JHAFA#V0D) confirms this industrial-grade temperature specification. It is not qualified for the extended -40°C to +105°C range denoted by the "G" suffix.
Which package type does R5F101JHAFA#V0 use?
R5F101JHAFA#V0 uses a 52-pin LQFP package with 0.65-mm pitch and 10 mm × 10 mm body size (RENESAS Code PLQP0052JA-A). The "#V0" suffix denotes tray packaging, and "FA" in the part number specifies the LQFP-0.65mm variant - distinct from LFQFP (FB) or HWQFN (NA) packages in the same family.
Can R5F101JHAFA#V0 operate from a single 1.8 V supply?
Yes, R5F101JHAFA#V0 supports operation from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, maximum clock frequency is reduced per datasheet specifications (typically ≤ 16 MHz), but all peripherals - including ADC, timers, and serial interfaces - remain fully functional. This enables direct integration with 1.8 V logic domains without level shifters.
How many analog input channels does R5F101JHAFA#V0 support?
R5F101JHAFA#V0 supports up to 26 analog input channels for its 10-bit A/D converter. Channel allocation depends on pin configuration and package; the 52-pin LQFP exposes 26 dedicated ANIx pins (e.g., ANI0 through ANI25), all usable simultaneously with proper sampling timing and reference setup.
