Renesas R5F100GGAFB#10

Overview

R5F100GGAFB#10 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), RTC, and multiple serial interfaces - deployed in industrial sensor nodes and battery-powered control modules.

For engineers reviewing the R5F100GGAFB#10 datasheet, R5F100GGAFB#10 pinout, R5F100GGAFB#10 application, or R5F100GGAFB#10 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), LFQFP-48 package (FB), on-chip data flash rewrite endurance (1M cycles), real-time clock calendar function, and support for LIN-bus UART communication.

Technical Context

The R5F100GGAFB#10 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting variable instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: a high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and a dedicated low-speed oscillator for watchdog and RTC operation.

Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock with alarm and correction, two to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) channels - all accessible via configurable GPIO with N-ch open-drain, TTL input, and pull-up options across 48 pins.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GGAFB#10?

The R5F100GGAFB#10 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under standard conditions (VDD = 3.3 V, TA = 25°C). The R5F100GGAFB#10 achieves this throughput while maintaining ultra-low power consumption - 66 μA/MHz in active mode - making it suitable for real-time control tasks in energy-constrained systems.

Does the R5F100GGAFB#10 support LIN bus communication, and which peripheral implements it?

Yes, the R5F100GGAFB#10 supports LIN bus communication via its UART peripheral, specifically UART0 and UART1 channels, which are LIN-bus compliant per ISO 17987. The R5F100GGAFB#10 includes hardware features such as automatic sync-break detection and configurable baud rate generation essential for LIN slave node timing accuracy. This eliminates the need for external LIN transceivers in basic body electronics applications.

What is the data flash endurance specification and operating voltage range for rewrites on the R5F100GGAFB#10?

The R5F100GGAFB#10 provides 8 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) with rewrite operation supported across the full supply range of VDD = 1.8 V to 5.5 V. This enables reliable parameter storage in battery-backed or wide-input-voltage industrial systems. The R5F100GGAFB#10 also supports background operation (BGO), allowing program execution to continue uninterrupted during data flash updates.

How does the R5F100GGAFB#10 handle real-time clock functionality, and what calendar capabilities does it offer?

The R5F100GGAFB#10 integrates a dedicated real-time clock (RTC) module with calendar support covering years 2000–2099, including leap-year correction, alarm interrupt, and clock correction functions. It accepts a 32.768 kHz crystal or external clock on the RTC_CLK pin and operates independently in STOP mode with only 0.57 μA current draw. The R5F100GGAFB#10's RTC is fully register-accessible and synchronized to the subsystem clock domain for deterministic timekeeping.

What package type and pin count does the R5F100GGAFB#10 use, and is it RoHS-compliant?

The R5F100GGAFB#10 uses a 48-pin LFQFP package (7 mm × 7 mm, 0.5 mm pitch), designated by the "FB" suffix in its part number. It is RoHS-compliant and moisture sensitivity level 3 (MSL3), qualified for standard reflow soldering processes. The R5F100GGAFB#10's pinout is shared across the RL78/G13 48-pin variants, enabling drop-in compatibility within the same memory/peripheral configuration group.
