Product details
Overview
R5F100GHGNA#W0 from Renesas is a 48-pin, HWQFN-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 modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GHGNA#W0 datasheet, R5F100GHGNA#W0 pinout, R5F100GHGNA#W0 application, or R5F100GHGNA#W0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G suffix), embossed tape packaging (#W0), HWQFN-48 (7 × 7 mm, 0.5 mm pitch) footprint, and on-chip debug support for rapid firmware validation in resource-constrained embedded designs.
Technical Context
The R5F100GHGNA#W0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting 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: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 8× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm/correction, 2–4 channel DMA, 3–10 channel I²C/Simplified I²C, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) channels - all configurable via register-based control without external timing components.

FAQ
What is the maximum operating frequency and performance of the R5F100GHGNA#W0?
The R5F100GHGNA#W0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this with a 3-stage pipeline and high-speed on-chip oscillator (±1.0% accuracy), enabling deterministic real-time execution for motor control and sensor processing tasks without external clock sources.
Does the R5F100GHGNA#W0 support in-system programming and secure firmware updates?
Yes, the R5F100GHGNA#W0 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features. Its self-programming capability - including boot swap function - enables secure, field-upgradable firmware with rollback protection for industrial deployments.
What are the low-power capabilities of the R5F100GHGNA#W0, and how do they benefit battery-powered designs?
The R5F100GHGNA#W0 offers HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, it maintains calendar RTC and voltage monitoring while drawing sub-μA current - extending CR2032 battery life to over five years in wireless sensor nodes without compromising timekeeping or safety monitoring.
Can the R5F100GHGNA#W0 interface directly with 1.8 V or 2.5 V peripherals?
Yes, the R5F100GHGNA#W0 supports different-potential interface operation: selected I/O ports tolerate 1.8 V, 2.5 V, or 3 V logic levels while powered from 1.6–5.5 V VDD. This eliminates level shifters when connecting to low-voltage sensors, displays, or RF modules - reducing BOM cost and board area.
What serial communication interfaces are integrated into the R5F100GHGNA#W0?
The R5F100GHGNA#W0 integrates up to 10 channels of I²C/Simplified I²C, 4 channels of UART/LIN, and 8 channels of CSI (SPI-compatible). These interfaces operate independently with dedicated registers and DMA support - enabling concurrent communication with displays, EEPROMs, sensors, and automotive networks without CPU intervention.
