Product details
Overview
R5F100PKDFA#X0 from Renesas is a 100-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 256 KB flash, 8 KB data flash, 20 KB RAM, 16-bit RL78 CPU core, and real-time clock with calendar support. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and targets low-power industrial control and sensor interface applications.
For engineers reviewing the R5F100PKDFA#X0 datasheet, R5F100PKDFA#X0 pinout, R5F100PKDFA#X0 application, or R5F100PKDFA#X0 equivalent, key selection criteria include its 100-pin LQFP package, integrated RTC with alarm/calendar, 26-channel 10-bit ADC, dual UART/LIN support, and ultra-low power STOP mode (0.57 μA).
Technical Context
The R5F100PKDFA#X0 implements the RL78 CISC CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, and background operation for data flash rewriting.
Its peripheral set includes up to 16 channels of 16-bit timer, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, and 2–8 CSI (SPI-compatible) channels - all configurable via register-based control without external glue logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLDFA#X0 | Same 100-pin LQFP package, 512 KB flash, 32 KB RAM, identical peripherals and power specs. | Higher memory capacity suits complex protocol stacks or local data buffering where R5F100PKDFA#X0's 256 KB is limiting. | Select when future firmware expansion or OTA update partitioning requires >256 KB code space. |
| R5F101PKDFA#X0 | Pin-compatible variant with no data flash (0 KB); otherwise identical flash size, RAM, peripherals, and package. | Used where EEPROM-like nonvolatile parameter storage is handled externally or unnecessary. | Choose when data flash functionality is unused - reduces cost and simplifies qualification for legacy designs. |
Compared with R5F100PKDFA#X0, R5F100PLDFA#X0 offers double flash and RAM for scalable firmware, while R5F101PKDFA#X0 removes data flash to lower cost - both retain identical pinout, timing, and peripheral compatibility for drop-in reuse in existing layouts.

FAQ
What is the operating temperature range for R5F100PKDFA#X0?
The R5F100PKDFA#X0 is rated for industrial operation from −40°C to +105°C (G-grade), making it suitable for under-hood automotive modules, factory automation controllers, and outdoor metering equipment where thermal resilience is critical. This rating is confirmed in the RL78/G13 datasheet Rev.3.80, Section 1.1.
Does R5F100PKDFA#X0 support in-system programming via UART?
Yes, R5F100PKDFA#X0 supports in-system programming using the built-in UART bootloader. The device can be programmed via UART pins P11 (RxD0) and P12 (TxD0) without external debug hardware, provided the boot option byte is configured correctly and the target enters boot mode on reset.
How many UART/LIN interfaces does R5F100PKDFA#X0 include?
R5F100PKDFA#X0 includes four UART/LIN interfaces (UART0–UART3), each capable of LIN 2.2-compliant communication with automatic break detection and sync field generation. This enables simultaneous connectivity to multiple LIN slaves in body control or lighting networks.
Is the data flash in R5F100PKDFA#X0 capable of wear leveling?
No, R5F100PKDFA#X0 data flash does not implement hardware wear leveling. However, its 1,000,000 write/erase cycle endurance (typical) and background operation allow firmware-level wear leveling algorithms to be implemented in user code using the flash library APIs provided by Renesas.
What debug interface does R5F100PKDFA#X0 use?
R5F100PKDFA#X0 uses the single-wire debug (SWD)-compatible on-chip debug interface via pins P50 (TOOLnTRST) and P51 (TOOLCLK), supporting full JTAG boundary scan and real-time trace capabilities through Renesas E2 studio and CS+ IDEs.
