Product details
Overview
R5F104BGGNA#20 from Renesas is a 32-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 96 KB flash, 12 KB RAM, and industrial-grade -40°C to +105°C operation (G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/SPI/I²C interfaces, RTC, and on-chip debug.
For engineers reviewing the R5F104BGGNA#20 datasheet, R5F104BGGNA#20 pinout, R5F104BGGNA#20 application, or R5F104BGGNA#20 equivalent, key selection criteria include its G-grade temperature rating, HWQFN-32 package with 0.5 mm pitch, 96 KB code flash with data flash shield window, and support for SNOOZE mode in battery-powered sensor nodes.
Technical Context
The R5F104BGGNA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz to 30.5 µs @ 32.768 kHz). It uses a dedicated low-speed on-chip oscillator for watchdog timer operation and supports background operation (BGO) during data flash rewriting.
Its peripheral set includes an Event Link Controller (ELC) enabling direct hardware-triggered peripheral activation (19–26 event types), Data Transfer Controller (DTC) with chain transfer capability, and simplified SPI (CSI) supporting up to 8 channels - all configured without CPU intervention for deterministic real-time response.

FAQ
What is the operating temperature range of the R5F104BGGNA#20?
The R5F104BGGNA#20 is rated for industrial operation from -40°C to +105°C (G-grade), making it suitable for under-hood automotive, factory automation, and outdoor metering applications where ambient temperatures exceed standard consumer-grade limits. This rating is confirmed in Renesas' ordering information table and applies specifically to the "G" suffix in the part number.
Does the R5F104BGGNA#20 support in-circuit debugging?
Yes, the R5F104BGGNA#20 supports full on-chip debugging via dedicated TOOLRxD (P50) and TOOLTxD (P51) pins, enabling programming, breakpoint setting, and real-time variable monitoring without consuming general-purpose UART resources. Its integrated debug interface complies with Renesas E1/E20 emulator protocols and requires no external debug probe hardware beyond standard JTAG/SWD adapters.
How much data flash memory does the R5F104BGGNA#20 include?
The R5F104BGGNA#20 includes 4 KB of data flash memory, separate from its 96 KB code flash. This data flash supports background operation (BGO), 1,000,000 write cycles (typical), and voltage-range operation from 1.8 V to 5.5 V - enabling reliable non-volatile parameter storage, calibration data logging, or firmware update staging without halting application execution.
What serial communication interfaces are available on the R5F104BGGNA#20?
The R5F104BGGNA#20 provides three UART channels (one with LIN support), up to eight CSI (simplified SPI) channels, and up to ten I²C/simplified I²C channels. These are distributed across multiplexed pins (e.g., P10–P15, P60–P62) and configurable via peripheral I/O redirection registers, allowing flexible assignment to match board layout and protocol requirements without hardware redesign.
Is the R5F104BGGNA#20 pin-compatible with other RL78/G14 variants in HWQFN-32?
Yes, the R5F104BGGNA#20 shares identical pinout, package dimensions (5 × 5 mm, 0.5 mm pitch), and electrical characteristics with all other RL78/G14 devices in the HWQFN-32 package - including R5F104BGANA#20 (A-grade) and R5F104BHANA#20 (128 KB flash). This enables drop-in replacement for qualification reuse, temperature grade upgrades, or memory scaling without PCB revision.
