Overview
R5F104GHGNA#20 from Renesas Electronics is a 48-pin LFQFP, 128 KB flash, 16 KB RAM, 8 KB data flash RL78/G14 16-bit microcontroller operating at up to 32 MHz with 44 DMIPS, ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and industrial-grade −40°C to +105°C operation for embedded control in motor drives, sensor nodes, and industrial HMI.
For engineers reviewing the R5F104GHGNA#20 datasheet, R5F104GHGNA#20 pinout, R5F104GHGNA#20 application, or R5F104GHGNA#20 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, integrated 10-bit 20-channel ADC, dual UART/LIN support, real-time clock with calendar, and hardware DTC/ELC for deterministic peripheral event handling without CPU intervention.
Technical Context
The R5F104GHGNA#20 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), multiply/divide/accumulate instructions, and 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and supports HALT/STOP/SNOOZE low-power modes.
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, RTC with alarm/calendar, watchdog timer, 8-bit DAC (2-channel), two comparators, and serial interfaces: 3–4 UART/LIN, 3–8 CSI, and 4–10 I²C channels - all configurable via Event Link Controller (ELC) for autonomous event chaining.

FAQ
What is the maximum operating frequency and corresponding DMIPS performance of the R5F104GHGNA#20?
The R5F104GHGNA#20 operates at up to 32 MHz with a measured performance of 44 DMIPS. This is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, including hardware multiply/divide. The high-speed on-chip oscillator supports ±1.0% accuracy across 1.8–5.5 V and −40°C to +105°C, eliminating need for external crystal in many applications.
Does the R5F104GHGNA#20 support LIN bus communication, and which UART channels are compliant?
Yes, the R5F104GHGNA#20 supports LIN 2.2 and SAE J2602 via its UART peripherals - specifically UART0 (P50/P51) and UART2 (P13/P14) - with built-in sync-break detection, checksum generation, and auto-wake capabilities. No external LIN transceiver is required for basic node functionality, though an external driver is needed for bus physical layer compliance.
What are the data flash endurance and voltage requirements for rewriting the R5F104GHGNA#20?
The R5F104GHGNA#20 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with background operation (BGO) enabled. Rewrites are supported across the full operating voltage range of 1.8 V to 5.5 V, allowing in-system updates without power sequencing constraints. The flash library reserves RAM starting at address FE900H for self-programming operations.
How does the Event Link Controller (ELC) enhance real-time responsiveness in the R5F104GHGNA#20?
The ELC in the R5F104GHGNA#20 enables up to 26 peripheral events (e.g., ADC conversion complete, timer match, UART receive) to trigger other peripherals directly - such as initiating a DTC transfer or toggling a GPIO - without CPU intervention. This reduces interrupt latency to <100 ns and frees the CPU for higher-layer tasks, critical in deterministic control loops.
What is the pin-compatible upgrade path from the R5F104GHGNA#20 within the RL78/G14 family?
The R5F104GLGNA#20 is a direct pin-compatible upgrade offering 512 KB flash and 48 KB RAM in the same 48-pin LFQFP-0.5 mm package. All peripherals, pin functions, and register maps remain identical - only flash/RAM capacities increase. No PCB or firmware changes are required beyond recompilation and linker script update to utilize expanded memory.
