Overview
R5F104GGAFB#10 from Renesas is a 48-pin LFQFP, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), 1.6–5.5 V supply, and integrated RTC, 10-bit ADC (16 ch), UART/SPI/I²C interfaces, and 16-bit timers - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104GGAFB#10 datasheet, R5F104GGAFB#10 pinout, R5F104GGAFB#10 application, or R5F104GGAFB#10 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), 0.5 mm pitch LFQFP-48 package, on-chip debug support, and BGO-capable 4 KB data flash for firmware updates without halting execution.
Technical Context
The R5F104GGAFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions. Its memory subsystem integrates 96 KB code flash (1 KB block size), 4 KB data flash with background operation (BGO), and 12 KB SRAM.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104GGAFB#10?
The R5F104GGAFB#10 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. At full speed, this yields ~2.1 mA total active current. Its ultra-low-power HALT and STOP modes reduce current to 0.60 μA (RTC + LVD only), making it ideal for intermittent-sensing applications.
Does the R5F104GGAFB#10 support in-system programming and secure firmware updates?
Yes, the R5F104GGAFB#10 supports full in-system programming via on-chip debug interface and includes flash shield window, block erase prohibition, and boot swapping - enabling secure, field-upgradable firmware with anti-rollback protection. The 4 KB data flash supports background operation (BGO) so updates occur without halting application code.
What are the key differences between the R5F104GGAFB#10 and R5F104GHAFB#10?
The R5F104GGAFB#10 and R5F104GHAFB#10 share identical 48-pin LFQFP-0.5 mm package, pinout, and peripheral set, but differ in memory: R5F104GGAFB#10 has 96 KB flash / 12 KB RAM, while R5F104GHAFB#10 upgrades to 128 KB flash / 16 KB RAM. Both are G-grade (-40°C to +105°C) and pin-compatible.
Can the R5F104GGAFB#10 interface directly with 1.8 V I²C peripherals?
Yes - the R5F104GGAFB#10 supports different-potential I/O operation. Its I²C pins (e.g., P60/SCLA0 and P61/SDAA0) tolerate 1.8 V logic levels and can be configured with open-drain outputs and internal pull-ups, enabling direct connection to 1.8 V I²C slaves without external level shifters.
What debug and development tools are officially supported for the R5F104GGAFB#10?
Renesas provides full toolchain support for the R5F104GGAFB#10, including CS+ IDE with compiler and debugger, E2 emulator Lite for on-chip debugging, and Renesas Flash Programmer for production programming. Third-party tools like IAR Embedded Workbench and SEGGER J-Link are also certified for use with this device.
