Product details
Overview
R5F101PKAFB#30 from Renesas is a 100-pin LFQFP-0.5mm-pitch 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA in RTC+LVD mode), and integrates 12-bit ADC (26 channels), UART/LIN, I²C, SPI, RTC, and watchdog timer - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101PKAFB#30 datasheet, R5F101PKAFB#30 pinout, R5F101PKAFB#30 application, or R5F101PKAFB#30 equivalent, key selection criteria include its 100-pin LFQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F101PKAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space, with flash organized in 1 KB blocks and security features including block erase prohibition and flash shield window.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, HALT/STOP/SNOOZE low-power modes, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM. Peripheral integration covers up to 26-channel 10-bit ADC, 16-bit timers (12 channels), real-time clock with calendar/alarm, and simplified SPI/UART/I²C interfaces.

Does the R5F101PKAFB#30 support hardware debugging?
Yes, the R5F101PKAFB#30 includes full on-chip debug functionality compatible with Renesas E2 emulator and E2 studio IDE. Debug access uses dedicated TOOLRxD/TOOLTxD pins (P11/P12) and supports breakpoints, watchpoints, and real-time variable inspection without halting peripheral operation.
What is the maximum ADC resolution and channel count supported by the R5F101PKAFB#30?
The R5F101PKAFB#30 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25), configurable reference voltages (AVREFP/AVREFM), and internal temperature sensor. Conversion time is 1.2 μs per sample at 10 MHz ADC clock, enabling high-speed sensor polling in closed-loop control.
Can the R5F101PKAFB#30 operate from a 1.8 V supply?
Yes, the R5F101PKAFB#30 operates across 1.6 V to 5.5 V, making it fully compatible with 1.8 V logic domains. Its I/O ports support different-potential interfacing, allowing direct connection to 1.8 V, 2.5 V, and 3.3 V peripherals without level shifters - verified across all operating modes including STOP and SNOOZE.
Is the R5F101PKAFB#30 pin-compatible with other RL78/G13 100-pin variants?
Yes, the R5F101PKAFB#30 shares identical 100-pin LFQFP mechanical footprint and pin assignment with all RL78/G13 devices in the FB package (e.g., R5F100PKAFB#30, R5F101PLAFB#30). Signal mapping, power/ground pin locations, and debug interface pins are functionally consistent across the family.
