Product details
Overview
R5F101PLAFA#10 from Renesas is a 100-pin LQFP-0.65mm, 16 KB flash, no data flash, industrial-grade RL78/G13 16-bit microcontroller operating from 1.6–5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), used in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101PLAFA#10 datasheet, R5F101PLAFA#10 pinout, R5F101PLAFA#10 application, or R5F101PLAFA#10 equivalent, key selection criteria include its 100-pin LQFP package, absence of on-chip data flash, -40°C to +85°C industrial temperature rating, and support for UART/LIN, I²C, and 10-bit ADC with internal temperature sensor.
Technical Context
The R5F101PLAFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer driven by dedicated low-speed oscillator.
Peripheral integration includes up to 10 I²C channels, 4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, 16× 16-bit timers, 10-bit A/D converter with 26 analog inputs, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.
Key Specifications

FAQ
Does R5F101PLAFA#10 include on-chip data flash memory?
No, R5F101PLAFA#10 contains 16 KB of code flash memory only and does not integrate data flash. This distinguishes it from the R5F100xxx series, which includes 4 KB data flash. Applications requiring nonvolatile parameter storage must use external EEPROM, FRAM, or utilize code flash sectors with wear-leveling firmware.
What is the maximum operating frequency and corresponding DMIPS rating for R5F101PLAFA#10?
R5F101PLAFA#10 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating is achieved using the high-speed on-chip oscillator, which maintains +/-1.0% accuracy across 1.8–5.5 V supply and -20 to +85°C ambient conditions - eliminating need for external crystal in many timing-tolerant applications.
Which communication interfaces are supported by R5F101PLAFA#10, and how are they mapped to pins?
R5F101PLAFA#10 supports UART/LIN (up to 4 channels), I²C (up to 10 channels), and CSI (SPI-compatible, up to 8 channels). These share pins such as P10 (SCK00/SCL00) and P11 (SI00/RxD0/SDA00), requiring software-selectable peripheral routing. No dedicated CAN or USB interfaces are integrated.
What power-saving modes are available on R5F101PLAFA#10, and what is the lowest achievable current draw?
R5F101PLAFA#10 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.57 μA - verified at VDD = 3.0 V and TA = 25°C. This enables multi-year operation on primary lithium batteries in remote monitoring applications without compromising timekeeping or voltage supervision.
Is R5F101PLAFA#10 pin-compatible with other RL78/G13 variants in the 100-pin LQFP package?
Yes, R5F101PLAFA#10 shares identical pinout and footprint with all other RL78/G13 devices in the 100-pin LQFP-0.65mm package (e.g., R5F100PLAFA#10, R5F101PLAFA#50), including matching power, ground, reset, and debug signal locations. Peripheral function allocation per pin is consistent across the family.
