Product details
Overview
R5F104PFAFA#10 from Renesas is a 100-pin LQFP-0.65 mm pitch, 96 KB flash, 5.5 KB RAM RL78/G14 16-bit MCU with ultra-low power operation (66 μA/MHz), 32 MHz max CPU speed, integrated 10-bit ADC (16 channels), UART/LIN, I²C, and RTC - deployed in industrial motor control and sensor interface modules.
For engineers reviewing the R5F104PFAFA#10 datasheet, R5F104PFAFA#10 pinout, R5F104PFAFA#10 application, or R5F104PFAFA#10 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade (D-grade), 1.6–5.5 V supply range, on-chip LVD with 14-level detection, and support for background data flash rewriting (1M write cycles).
Technical Context
The R5F104PFAFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It integrates a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral event routing without CPU intervention.
Its memory subsystem includes 96 KB code flash (1 KB block size, security-protected erase/write), 4 KB data flash with background operation (BGO), and 5.5 KB SRAM. Power management features HALT, STOP, and SNOOZE modes, achieving 0.60 μA RTC+LVD-only operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104GFAFA#10 | Same package and pinout; 128 KB flash, 16 KB RAM, 48-pin LQFP variant - not pin-compatible due to reduced pin count. | Higher memory capacity suits larger protocol stacks but lacks 100-pin I/O scalability for multi-channel I/O expansion. | Select when application requires more flash/RAM and fewer I/O lines; verify PCB layout compatibility before substitution. |
| R5F105PJAPFB#30 | RL78/G15 family; 100-pin LFQFP, 128 KB flash, 12 KB RAM, enhanced ELC and DTC features, same voltage/temp specs. | Supports higher peripheral concurrency and deeper sleep modes; targets next-gen designs needing extended feature headroom. | Choose for new designs requiring future-proofing; not drop-in due to register map differences and bootloader incompatibility. |
