Product details
Overview
R5F100GGAFB#V0 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 V to 5.5 V across –40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (26 channels), RTC, UART, I²C, CSI, and 16-bit timers for embedded control in battery-powered and thermally constrained systems.
For engineers reviewing the R5F100GGAFB#V0 datasheet, R5F100GGAFB#V0 pinout, R5F100GGAFB#V0 application, or R5F100GGAFB#V0 equivalent, key selection criteria include its industrial-grade temperature rating, integrated data flash with background operation, low-power SNOOZE/HALT/STOP modes, and support for LIN-bus via UART - critical for motor control, sensor hubs, and industrial IoT edge nodes.
Technical Context
The R5F100GGAFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash supporting 1M rewrite cycles and background operation, and 12 KB on-chip RAM.
Peripherals are tightly coupled to low-power operation: the 10-bit ADC supports up to 26 analog inputs with internal 1.45 V reference and temperature sensor; real-time clock provides calendar functionality with alarm and correction; and serial interfaces include up to 10-channel simplified I²C, 8-channel CSI, and 4-channel UART with LIN support - all configurable without exiting low-power states.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GGAFB#V0?
The R5F100GGAFB#V0 operates at up to 32 MHz using its high-speed on-chip oscillator and achieves 41 DMIPS (Dhrystone MIPS) at that frequency. This performance level is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80) and reflects optimized CISC execution with 3-stage pipeline efficiency. The R5F100GGAFB#V0 maintains this rating across its full industrial temperature range (–40°C to +105°C) and supply voltage (1.6 V to 5.5 V).
Does the R5F100GGAFB#V0 support LIN communication, and how is it implemented?
Yes, the R5F100GGAFB#V0 supports LIN communication through its UART peripheral, which includes hardware features compliant with LIN 2.2 and SAE J2602 standards. The UART supports automatic sync-break detection, checksum calculation, and configurable baud rates - all essential for LIN slave node operation. This capability is documented in Section 1.1 "Features" and Section 22 "UART" of the R5F100GGAFB#V0 datasheet (R01DS0131EJ0380).
What is the data flash endurance and voltage range for programming the R5F100GGAFB#V0?
The R5F100GGAFB#V0 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) and programmable across a supply voltage range of 1.8 V to 5.5 V. Background operation (BGO) allows code execution from main flash during data flash rewrites. These specifications are explicitly stated in the "Data Flash Memory" subsection of the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80, page 1).
How does the R5F100GGAFB#V0 achieve ultra-low-power operation, and what are the lowest current modes?
The R5F100GGAFB#V0 achieves ultra-low-power operation via multiple hardware-controlled sleep modes: HALT mode draws just 0.57 μA when only RTC and LVD remain active, STOP mode consumes 0.73 μA (typical), and SNOOZE mode enables selective peripheral operation while CPU sleeps. These values are measured at VDD = 3.0 V and TA = 25°C per the datasheet's electrical characteristics table. The R5F100GGAFB#V0 also features 66 μA/MHz active current efficiency.
Is the R5F100GGAFB#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GGAFB#V0 is pin-compatible with all other RL78/G13 devices in the 48-pin LFQFP (FB) package, including R5F100GGAFA#V0 (LQFP), R5F100GGANA#U0 (HWQFN), and R5F101GGAFB#V0 (same package, no data flash). Pin functions are consistent across the family per the "Pin Configuration" section (page 13 onward) of R01DS0131EJ0380, ensuring drop-in replacement within the same package variant.
