Product details
Overview
R5F100GHAFB#30 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 with calendar/alarm, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100GHAFB#30 datasheet, R5F100GHAFB#30 pinout, R5F100GHAFB#30 application, or R5F100GHAFB#30 equivalent, key selection criteria include its industrial-grade −40°C to +105°C operation (G-grade), 48-pin LFQFP-0.5mm pitch package, on-chip debug support, self-programmable flash with boot swap, and BGO-capable data flash for concurrent execution and rewriting.
Technical Context
The R5F100GHAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction timing from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed main system clock (up to 32 MHz) and independent low-speed subsystem clock for RTC and LVD.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one real-time clock with calendar and alarm, one watchdog timer, two to four DMA channels, and serial interfaces including CSI (SPI-compatible), UART/LIN, and I²C - all configurable via dedicated SFRs and interrupt vectors mapped to the 1 MB address space.

FAQ
What is the maximum operating temperature specification for the R5F100GHAFB#30?
The R5F100GHAFB#30 is rated for industrial operation from −40°C to +105°C (G-grade), verified per Renesas qualification standards. This makes it suitable for under-hood automotive modules, outdoor metering equipment, and factory-floor controllers where ambient temperatures exceed +85°C. The device maintains full functionality-including RTC, ADC accuracy, and flash write endurance-across this full range.
Does the R5F100GHAFB#30 support in-system programming via standard interfaces?
Yes, the R5F100GHAFB#30 supports in-system programming via its on-chip debug interface using Renesas E1/E20 emulators or compatible third-party tools. It does not require external programming voltage (VPP) and enables full flash read/write/erase through the debug port - allowing firmware updates in the field without removing the R5F100GHAFB#30 from the PCB.
How many serial communication interfaces does the R5F100GHAFB#30 integrate?
The R5F100GHAFB#30 integrates up to eight serial interfaces: two to four UART/LIN channels, three to ten I²C/Simplified I²C channels, and two to eight CSI (SPI-compatible) channels. Pin multiplexing allows dynamic allocation - for example, P10/P11/P12 can be configured as SCK00/SI00/SO00 for CSI0, or as SCL00/SDA00 for I²C0, depending on application needs.
Can the R5F100GHAFB#30 operate from a single 1.8 V supply?
Yes, the R5F100GHAFB#30 operates across 1.6 V to 5.5 V, so it functions reliably at 1.8 V. At this voltage, maximum frequency is reduced to approximately 16 MHz (per Renesas DC characteristics), but all peripherals - including ADC, RTC, and serial interfaces - remain fully operational. This enables direct use with 1.8 V logic families and low-voltage battery systems.
Is there hardware support for cryptographic operations in the R5F100GHAFB#30?
No, the R5F100GHAFB#30 does not include dedicated cryptographic accelerators (e.g., AES, SHA, TRNG). Security relies on software libraries and Renesas' flash protection features (block erase prohibition, flash shield window). For applications requiring certified crypto, consider the RL78/G14 or RA2 series, which offer hardware AES engines and TrustZone-like isolation.
