Product details
Overview
R5F100FFGFP#50 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V. It integrates a real-time clock, 10-bit ADC (12-channel), UART/LIN, I²C, and CSI interfaces, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode) for battery-powered industrial sensor nodes and smart metering endpoints.
For engineers reviewing the R5F100FFGFP#50 datasheet, R5F100FFGFP#50 pinout, R5F100FFGFP#50 application, or R5F100FFGFP#50 equivalent, key selection criteria include its 44-pin LQFP package with 12 analog input channels, integrated LIN transceiver support, RTC calendar function, and verified 41 DMIPS performance at 32 MHz - all within -40°C to +105°C industrial temperature grade.
Technical Context
The R5F100FFGFP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features on-chip debug, self-programming flash with boot swap, and background operation during data flash rewriting.
Power management includes HALT, STOP, and SNOOZE modes; voltage detection (14-level LVD) and POR are integrated. The device supports DMA (4 channels), 16×16/32÷32 hardware multiplier/divider, and up to 16 × 16-bit timer channels - all optimized for deterministic real-time control in resource-constrained embedded systems.

FAQ
What is the maximum operating frequency and associated DMIPS rating for the R5F100FFGFP#50?
The R5F100FFGFP#50 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects Dhrystone 2.1 benchmark results under typical conditions and confirms deterministic real-time execution capability for control-loop-critical applications such as motor drives and sensor fusion.
Does the R5F100FFGFP#50 include an integrated real-time clock with calendar functionality?
Yes, the R5F100FFGFP#50 includes a dedicated real-time clock (RTC) module supporting full calendar operation for 99 years, alarm generation, and automatic clock correction. It operates independently in STOP mode with only RTC and LVD enabled, drawing just 0.57 μA - eliminating need for external RTC ICs in time-aware embedded systems.
What analog features are integrated into the R5F100FFGFP#50?
The R5F100FFGFP#50 integrates a 10-bit successive-approximation ADC with 12 analog input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. These features enable direct measurement of thermistors, voltage dividers, and environmental sensors without external signal conditioning in most industrial monitoring applications.
Is the R5F100FFGFP#50 qualified for industrial temperature range operation?
Yes, the R5F100FFGFP#50 is rated for operation from −40°C to +105°C (G-grade), making it suitable for demanding industrial environments including factory automation controllers, outdoor metering equipment, and HVAC systems where ambient thermal stress exceeds commercial-grade limits.
