Product details
Overview
R5F101PJAFA#10 from Renesas is a 100-pin LQFP-0.65mm microcontroller in the RL78/G13 family, featuring 64 KB flash memory, 4 KB data flash, 4 KB RAM, 10-bit ADC (16 channels), and real-time clock with calendar function - designed for low-power industrial control and sensor interface applications operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F101PJAFA#10 datasheet, R5F101PJAFA#10 pinout, R5F101PJAFA#10 application, or R5F101PJAFA#10 equivalent, key selection criteria include its 100-pin LQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and integrated peripherals including UART, I²C, CSI, 16-bit timers, and low-voltage detection.
Technical Context
The R5F101PJAFA#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 10-bit A/D converter with up to 16 analog inputs, internal reference voltage (1.45 V), and temperature sensor.
Power management includes HALT, STOP, and SNOOZE modes, achieving 66 μA/MHz active current and 0.57 μA RTC+LVD operation. The device supports self-programming of code flash with boot swap and flash shield window functions, but excludes on-chip data flash memory (per R5F101x designation).

It operates independently in STOP mode with only 0.57 μA current draw when paired with the on-chip LVD, making it ideal for time-stamped logging and scheduled wake-up tasks.
What is the operating temperature grade of the R5F101PJAFA#10?
The R5F101PJAFA#10 is rated for industrial operation from -40°C to +85°C (D-grade), as indicated by the 'D' in the part number's field-of-application segment. This rating is validated across all electrical specifications and ensures reliable performance in factory-floor, outdoor, and uncontrolled-environment deployments.
How many analog-to-digital converter (ADC) channels does the R5F101PJAFA#10 support?
The R5F101PJAFA#10 features a 10-bit successive-approximation ADC with up to 16 input channels. It includes an internal 1.45 V reference voltage and an integrated temperature sensor - both accessible in HS (high-speed main) mode - enabling precision sensor measurements without external references.
Is the R5F101PJAFA#10 pin-compatible with other RL78/G13 devices in the same package?
Yes, the R5F101PJAFA#10 shares identical pinout and electrical characteristics with all other 100-pin LQFP RL78/G13 variants (e.g., R5F100PJAFA#10, R5F101PLAFA#10), enabling drop-in replacement within the same package footprint.
