Product details
Overview
R5F104GJGNA#W0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G14 microcontroller with 192 KB flash, 8 KB data flash, 20 KB RAM, and industrial-grade operation up to +105°C. It integrates a 32 MHz RL78 CPU core (44 DMIPS), 10-bit 16-channel ADC, RTC with calendar, dual UART/LIN, 4-channel I²C, and ultra-low-power modes including 0.60 μA STOP mode.
For engineers reviewing the R5F104GJGNA#W0 datasheet, R5F104GJGNA#W0 pinout, R5F104GJGNA#W0 application, or R5F104GJGNA#W0 equivalent, key selection criteria include its 48-pin HWQFN (7×7 mm, 0.5 mm pitch) package, G-grade temperature rating (−40 to +105°C), integrated LIN-capable UARTs for automotive body electronics, and hardware DTC/ELC for deterministic peripheral event handling without CPU intervention.
Technical Context
The R5F104GJGNA#W0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). Its power architecture enables HALT, STOP, and SNOOZE modes, with real-time clock and low-voltage detector (LVD) configurable across 14 levels for system-level safety monitoring.
Peripheral integration includes Event Link Controller (ELC) supporting 26 event sources linked to functions like ADC triggers or timer starts, and Data Transfer Controller (DTC) enabling background data flash rewriting (BGO) while executing code from program memory - critical for firmware-over-the-air updates in field-deployed devices.

FAQ
What is the operating temperature range for the R5F104GJGNA#W0?
The R5F104GJGNA#W0 is rated for industrial applications with an operating ambient temperature range of −40°C to +105°C (G-grade). This specification is validated per Renesas' qualification standards and applies across full voltage (1.6–5.5 V) and frequency (up to 32 MHz) operation - making it suitable for under-hood automotive and factory-floor industrial environments where thermal resilience is critical. The R5F104GJGNA#W0 maintains specified timing and analog performance across this full range.
Does the R5F104GJGNA#W0 support LIN bus communication?
Yes, the R5F104GJGNA#W0 supports LIN bus communication via two dedicated UART channels that implement LIN 2.2A protocol features including automatic sync-break detection, checksum generation (classic and enhanced), and configurable baud rates. These UARTs operate independently with separate clock domains and can be assigned to pins such as P17 (TRDIOA0 mode) for direct LIN physical layer interfacing - eliminating need for external transceivers in many body-control applications.
What debug interface does the R5F104GJGNA#W0 use?
The R5F104GJGNA#W0 uses Renesas' single-wire debug (SWD) interface compatible with the E2/E2 Lite emulators. It supports real-time trace, flash programming, and non-intrusive breakpoints without requiring dedicated debug pins - the interface shares functionality with P137 (INTP0) and P121/P122 (X1/X2) pins. Full on-chip debug capabilities include memory inspection, register access, and flash shield window configuration for secure firmware development.
How much data flash endurance does the R5F104GJGNA#W0 provide?
The R5F104GJGNA#W0 provides 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. This endurance enables reliable storage of calibration data, device configuration, or usage logs in applications like smart meters and industrial controllers. Background operation (BGO) allows concurrent code execution during rewrites, and the flash library reserves specific RAM regions (e.g., F9F00H start address) for safe self-programming sequences.
Is the R5F104GJGNA#W0 pin-compatible with other RL78/G14 variants in HWQFN-48?
Yes, the R5F104GJGNA#W0 is fully pin-compatible with all RL78/G14 family members offered in the 48-pin HWQFN package (e.g., R5F104GHGNA#W0, R5F104GKGNA#W0), sharing identical pin count, pitch (0.5 mm), mechanical footprint (7×7 mm), and pin function mapping. This allows direct substitution within the same PCB layout when scaling flash/RAM resources - provided software is recompiled to match the target device's memory map and peripheral enable settings.
