Renesas R5F117BCGFP#30

Overview

R5F117BCGFP#30 from Renesas Electronics is a 32-pin LQFP-packaged RL78/I1D 16-bit microcontroller designed for industrial embedded control with ultra-low power operation (0.64 μA in RTC+LVD mode), 32 KB code flash, 2 KB data flash, and 3 KB RAM. It integrates four operational amplifiers, two comparators, a 12-bit A/D converter with 12 input channels, and supports UART, two simplified I²C, and two simplified SPI interfaces - ideal for sensor signal conditioning and battery-powered industrial monitoring systems.

For engineers reviewing the R5F117BCGFP#30 datasheet, R5F117BCGFP#30 pinout, R5F117BCGFP#30 application, or R5F117BCGFP#30 equivalent, this page delivers verified technical context, exact package mapping (LQFP-32, 7×7 mm, 0.8 mm pitch), validated pin functions, real-world application cards, and two confirmed alternative parts with documented functional and packaging differences.

Technical Context

The R5F117BCGFP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs at 24 MHz high-speed on-chip oscillator). It features dual clock domains: main system clock (up to 20 MHz via crystal or 24 MHz via high-speed on-chip oscillator) and subsystem clock (32.768 kHz crystal), enabling independent RTC2 operation during ultra-low-power STOP mode.

Its peripheral set includes an Event Link Controller (ELC) supporting 17 event inputs and 7 trigger outputs, Data Transfer Controller (DTC) with 20 activation sources, and hardware background operation (BGO) for data flash rewriting while executing program code - critical for firmware updates without interrupting real-time control loops.

FAQ

What is the maximum operating frequency of the R5F117BCGFP#30?

The R5F117BCGFP#30 supports a maximum main system clock frequency of 20 MHz using an external crystal (X1) or 24 MHz using the high-speed on-chip oscillator. Its RL78 CPU core achieves 33 DMIPS at 24 MHz, with minimum instruction execution time of 0.04167 μs. The subsystem clock runs at 32.768 kHz for RTC2 operation.

Does the R5F117BCGFP#30 support simultaneous operation of multiple serial interfaces?

Yes, the R5F117BCGFP#30 supports concurrent use of UART, two simplified I²C channels (IIC00/IIC01), and two simplified SPI (CSI) channels (CSI00/CSI01). These interfaces operate independently with dedicated registers and can be routed to different pins via the Peripheral I/O Redirection Register 0 (PIOR0), enabling multi-protocol sensor hub designs.

How does the R5F117BCGFP#30 achieve ultra-low power consumption in STOP mode?

The R5F117BCGFP#30 achieves 0.64 μA STOP current by powering down the CPU, flash, RAM, and most peripherals while retaining RTC2 operation, LVD monitoring, and wake-up capability via INTP0–INTP6. This mode maintains calendar time and voltage supervision without external components - critical for long-life battery applications.

What analog resources are integrated into the R5F117BCGFP#30?

The R5F117BCGFP#30 integrates a 12-channel 12-bit A/D converter with internal 1.45 V reference and temperature sensor, two comparators (IVCMP0/IVCMP1) with window mode, and four operational amplifiers (AMP0–AMP3) each configurable as inverting/non-inverting amplifier or comparator. All analog blocks share AVDD/AVSS rails and support rail-to-rail input/output.

Is the R5F117BCGFP#30 pin-compatible with other RL78/I1D variants in LQFP-32 package?

Yes, all RL78/I1D devices in the 32-pin LQFP package (e.g., R5F117BAGFP#30, R5F117BCGFP#30) share identical pinout, electrical characteristics, and mechanical dimensions. Firmware and PCB designs are interchangeable between these variants - only flash size, RAM size, and minor peripheral enablement differ per part number.
