Product details
Overview
R5F104GFANA#20 from Renesas is a 48-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 96 KB flash, 5.5 KB RAM, and industrial-grade operation (−40°C to +105°C). It delivers 44 DMIPS at 32 MHz, supports ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 10-bit ADC (12 channels), and RTC for embedded control in space-constrained industrial sensors.
For engineers reviewing the R5F104GFANA#20 datasheet, R5F104GFANA#20 pinout, R5F104GFANA#20 application, or R5F104GFANA#20 equivalent, key selection criteria include its 48-pin HWQFN-0.5mm package, −40°C to +105°C industrial temperature rating, 96 KB code flash with data flash, and integrated analog peripherals including 10-bit ADC and RTC with calendar function.
Technical Context
The R5F104GFANA#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 single 1.6–5.5 V supply and includes on-chip power-on-reset (POR) and voltage detector (LVD) with 14 selectable levels.
Peripheral integration includes Data Transfer Controller (DTC), Event Link Controller (ELC), 16-bit Timer Array Unit (TAU), 12-bit interval timer, real-time clock with calendar/alarm/correction, watchdog timer, and simplified SPI (CSI), UART/LIN, and I²C interfaces - all optimized for deterministic low-power operation in resource-constrained systems.

FAQ
What is the maximum operating frequency and core performance of the R5F104GFANA#20?
The R5F104GFANA#20 operates at up to 32 MHz with the RL78 CPU core, delivering 44 DMIPS. Its minimum instruction execution time is 0.03125 µs at 32 MHz using the high-speed on-chip oscillator, and it supports configurable clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This performance level is confirmed in the RL78/G14 datasheet Rev. 3.70 for the R5F104GFANA#20 variant.
Does the R5F104GFANA#20 include an integrated DAC or only ADC functionality?
The R5F104GFANA#20 includes a 10-bit ADC with up to 12 analog input channels and internal 1.45 V reference, but it does not integrate a D/A converter. The RL78/G14 family documentation explicitly lists D/A converter availability as "None or up to two channels" depending on variant, and the R5F104GFANA#20 part number mapping confirms zero DAC channels. Analog output must be implemented externally or via PWM with filtering.
What is the industrial temperature rating and package type of the R5F104GFANA#20?
The R5F104GFANA#20 is rated for −40°C to +105°C operation (G-grade industrial qualification) and housed in a 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch) with exposed thermal pad. The 'G' in the part number denotes industrial temperature grade, and the 'NA' suffix specifies the HWQFN package per Renesas ordering information in R01DS0053EJ0370.
How much flash and RAM memory does the R5F104GFANA#20 provide?
The R5F104GFANA#20 provides 96 KB of code flash memory, 4 KB of data flash memory, and 5.5 KB of on-chip RAM. These values are confirmed in the RL78/G14 memory capacity table (Page 2 of R01DS0053EJ0370), where 'F' in the ROM capacity field corresponds to 96 KB, and the 48-pin row lists 5.5 KB RAM for variants ending in 'F'.
What debug interface options are supported by the R5F104GFANA#20?
The R5F104GFANA#20 supports on-chip debugging via dedicated TOOLRxD (P50) and TOOLTxD (P51) pins, enabling full in-circuit debugging without external emulators. It also supports the standard SWD interface through the same pins when configured appropriately. No JTAG port is present; debug capability is limited to the Renesas E1/E20 emulator protocol over the TOOL interface, as specified in the RL78/G14 hardware manual.
