Product details
Overview
R5F100GHGFB#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 at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE 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 R5F100GHGFB#V0 datasheet, R5F100GHGFB#V0 pinout, R5F100GHGFB#V0 application, or R5F100GHGFB#V0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), LFQFP-48 package (0.5 mm pitch), on-chip debug support, self-programmable flash with boot swap, and real-time clock with calendar/alarm functionality.
Technical Context
The R5F100GHGFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, 16-bit timers (12 channels), UART/LIN, I²C, CSI, and DMA (4 channels) for deterministic peripheral handling.
Power management includes an on-chip POR circuit, 14-level voltage detector (LVD) with interrupt/reset options, and multiple low-power modes optimized for intermittent sensing and wake-on-event operation. The device supports background operation (BGO) during data flash rewriting and uses dedicated RAM areas (e.g., FAF00H for R5F100xJ variants) for flash library execution.

What is the maximum operating frequency and associated performance of the R5F100GHGFB#V0?
The R5F100GHGFB#V0 operates at up to 32 MHz with a performance rating of 41 DMIPS. Its high-speed on-chip oscillator achieves ±1.0% accuracy across 1.8 V to 5.5 V and -40°C to +85°C, enabling reliable timing without external crystals in many applications. This speed supports real-time control loops, protocol stacks, and sensor fusion algorithms directly on the R5F100GHGFB#V0.
Does the R5F100GHGFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F100GHGFB#V0 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features for security. Its boot swap function allows safe dual-bank firmware updates - critical for maintaining uptime in remote R5F100GHGFB#V0 deployments such as industrial gateways or metering devices.
How does the R5F100GHGFB#V0 manage power in battery-constrained applications?
The R5F100GHGFB#V0 offers three ultra-low-power modes: HALT (66 μA/MHz), STOP (0.57 μA with RTC and LVD active), and SNOOZE (fast wake-up with peripheral operation). These modes, combined with configurable clock gating and event-driven wake-up sources, enable multi-year operation on coin cells - a key advantage of the R5F100GHGFB#V0 in wireless sensor networks.
Can the R5F100GHGFB#V0 interface directly with 1.8 V or 2.5 V peripherals?
Yes, the R5F100GHGFB#V0 supports different-potential I/O operation, allowing its GPIOs to safely interface with 1.8 V, 2.5 V, and 3.0 V logic families without external level shifters. This capability is enabled by configurable input buffer thresholds and N-ch open-drain outputs with VDD or EVDD withstand voltage - simplifying design and reducing bill-of-materials for the R5F100GHGFB#V0.
What serial communication interfaces are integrated into the R5F100GHGFB#V0?
The R5F100GHGFB#V0 integrates UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (Simplified SPI, up to 8 channels).
