Product details
Overview
R5F100PLAFA#V0 from Renesas is a 100-pin LQFP-0.65mm, 512 KB flash, 32 KB RAM RL78/G13 16-bit MCU with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated 10-bit ADC (26 channels), RTC, and multiple serial interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100PLAFA#V0 datasheet, R5F100PLAFA#V0 pinout, R5F100PLAFA#V0 application, or R5F100PLAFA#V0 equivalent, key selection criteria include its 512 KB code flash with self-programming, 32 KB RAM, 100-pin LQFP package, -40°C to +85°C industrial temperature grade (A-grade), and support for LIN-compliant UART, I²C, and CSI serial protocols in resource-constrained embedded control designs.
Technical Context
The R5F100PLAFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz high-speed oscillator) to 30.5 μs (@32.768 kHz subsystem clock).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFB#V0 | Same core, memory, and peripherals but in 100-pin LFQFP (0.5-mm pitch); smaller footprint, higher pin density | Preferred for space-constrained PCBs where 0.5-mm pitch assembly is supported | Select when board layout requires reduced package area and fine-pitch reflow capability is available |
| R5F101PLAFA#V0 | Identical package and pinout but lacks data flash memory (0 KB vs. 8 KB); same 512 KB code flash and 32 KB RAM | Suitable for applications requiring only code storage and no nonvolatile parameter logging | Choose when firmware-only updates suffice and EEPROM-like data retention is unnecessary |
Compared with R5F100PLAFA#V0, R5F100PLAFB#V0 offers identical functionality in a denser package for compact designs, while R5F101PLAFA#V0 removes data flash to reduce cost and power in code-only deployments - both retain full pin compatibility and software portability.
