Product details
Overview
R5F100PFDFA#X0 from Renesas is a 100-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 96 KB flash memory, 8 KB data flash, 8 KB RAM, 16-bit RL78 CPU core, and real-time clock with calendar function. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode), targeting battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F100PFDFA#X0 datasheet, R5F100PFDFA#X0 pinout, R5F100PFDFA#X0 application, or R5F100PFDFA#X0 equivalent, key selection criteria include its 100-pin LQFP package, integrated 10-bit A/D converter (26 channels), dual UART/LIN support, and hardware multiplier/divider for deterministic motor control loops.
Technical Context
The R5F100PFDFA#X0 implements the RL78 CISC CPU core with 3-stage pipeline and configurable instruction timing (0.03125 μs min @32 MHz). It integrates a 12-bit interval timer, 16-bit timers (12 channels), and background operation-capable data flash for firmware updates without halting execution.
Its power architecture includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and a high-accuracy ±1.0% on-chip oscillator (32 MHz option). The device supports multiple serial interfaces - up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - enabling multi-peripheral system integration.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100PFDFA#X0?
The R5F100PFDFA#X0 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS (Dhrystone MIPS) at that frequency. This performance level is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80) and reflects the efficiency of the 3-stage pipeline RL78 CPU core under typical operating conditions.
Does the R5F100PFDFA#X0 include an integrated temperature sensor, and if so, how is it accessed?
Yes, the R5F100PFDFA#X0 includes an on-chip temperature sensor usable only in HS (high-speed main) mode. It is accessed via the ANI25 analog input channel and requires calibration using the factory-trimmed value stored in ROM. The sensor output is digitized by the 10-bit A/D converter and supports system thermal monitoring without external components.
How many UART/LIN channels does the R5F100PFDFA#X0 support, and are they hardware-independent?
The R5F100PFDFA#X0 supports up to four independent UART/LIN channels (UART0–UART3), each with dedicated registers, baud rate generators, and LIN-specific features like sync-break detection and checksum calculation. These channels operate concurrently without resource contention, enabling simultaneous communication with multiple subsystems such as displays, sensors, and gateways.
What packaging and lead finish does the R5F100PFDFA#X0 use, and is it RoHS-compliant?
The R5F100PFDFA#X0 uses a 100-pin plastic LQFP package (14 × 20 mm, 0.65-mm pitch) with matte tin lead finish and is fully RoHS-compliant (lead-free, halogen-free per JEDEC J-STD-609). Its RENESAS Code is PLQP0100JC-A, and it ships in embossed tape (#X0 packaging specification), suitable for automated SMT assembly.
Can the R5F100PFDFA#X0 perform flash self-programming while executing code from another memory region?
Yes, the R5F100PFDFA#X0 supports flash self-programming with boot swap and flash shield window functions. Code execution can continue from non-erased flash blocks during data flash rewriting, enabled by background operation (BGO) mode - allowing seamless firmware updates without halting real-time tasks or interrupt servicing.
