Renesas R5F100PJGFA#30

Overview

R5F100PJGFA#30 from Renesas is a 100-pin LFQFP, 0.5-mm pitch, industrial-grade (−40°C to +105°C) RL78/G13 16-bit MCU with 192 KB flash, 8 KB data flash, 16 KB RAM, and integrated RTC/LVD. It delivers 41 DMIPS at 32 MHz, operates from 1.6–5.5 V, and targets battery-powered industrial control and sensor nodes requiring ultra-low power (0.57 μA in RTC+LVD mode).

For engineers reviewing the R5F100PJGFA#30 datasheet, R5F100PJGFA#30 pinout, R5F100PJGFA#30 application, or R5F100PJGFA#30 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, 192 KB/8 KB flash/data flash split, 16-bit RL78 CPU core with 3-stage pipeline, 16-channel 16-bit timers, and support for LIN-bus UART and background data flash rewriting.

Technical Context

The R5F100PJGFA#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @ 32 MHz). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer driven by dedicated low-speed oscillator.

Its peripheral set includes up to 16-channel 16-bit timers, 10-bit A/D converter with 26 analog inputs and internal temperature sensor, 3–10 channel I²C/Simplified I²C, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) interfaces - all operating across the full 1.6–5.5 V supply range.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100PJGFA#30?

The R5F100PJGFA#30 operates at up to 32 MHz with its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under these conditions, and the oscillator maintains ±1.0% accuracy across VDD = 1.8–5.5 V and TA = −20 to +85°C - enabling deterministic real-time control without external crystal dependency.

Does the R5F100PJGFA#30 support background data flash rewriting while executing application code?

Yes, the R5F100PJGFA#30 supports background operation (BGO) for data flash rewriting. This allows the CPU to continue executing instructions from program memory while simultaneously erasing or programming the 8 KB data flash - essential for logging fault events, storing calibration data, or updating configuration parameters without interrupting real-time tasks.

What are the power consumption characteristics of the R5F100PJGFA#30 in low-power modes?

The R5F100PJGFA#30 achieves 0.57 μA in STOP mode with only RTC and LVD active, and 66 μA/MHz in active mode. These values are measured at VDD = 1.8–5.5 V and TA = −40 to +105°C. Its HALT, STOP, and SNOOZE modes provide scalable energy savings for intermittent-sensing applications where duty cycling is critical to battery longevity.

Which communication interfaces does the R5F100PJGFA#30 support for industrial bus connectivity?

The R5F100PJGFA#30 supports UART with LIN-bus protocol compliance (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (SPI-compatible serial interface, up to 8 channels). These interfaces operate across the full 1.6–5.5 V supply range and support multi-voltage I/O, enabling direct connection to 1.8 V, 2.5 V, or 3.0 V peripherals without external level shifters.

How many analog input channels and what A/D resolution does the R5F100PJGFA#30 provide?

The R5F100PJGFA#30 integrates a 10-bit successive-approximation A/D converter with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor - both accessible via dedicated A/D channels - supporting precision sensor interfacing and thermal monitoring without external components.
