Product details
Overview
R5F104MFGFA#30 from Renesas is a 80-pin LQFP-0.65 mm pitch, industrial-grade (TA = −40 to +85°C) RL78/G14 16-bit MCU with 192 KB flash, 20 KB RAM, and 8 KB data flash. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, and features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), making it suitable for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F104MFGFA#30 datasheet, R5F104MFGFA#30 pinout, R5F104MFGFA#30 application, or R5F104MFGFA#30 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options for design-in and long-term supply planning.
Technical Context
The R5F104MFGFA#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a 12-bit interval timer, calendar-based real-time clock (RTC), and watchdog timer with dedicated low-speed oscillator.
Peripheral integration includes 10-channel 10-bit A/D converter (with internal 1.45 V reference and temperature sensor), two 8-bit D/A outputs, up to 12 × 16-bit timers (TAU, RJ, RD, RG), 4–10 I²C channels, 3–4 UART/LIN interfaces, and 3–8 CSI/SPI channels - all coordinated via Event Link Controller (ELC) and Data Transfer Controller (DTC).

FAQ
What is the maximum operating frequency and core performance of the R5F104MFGFA#30?
The R5F104MFGFA#30 operates at up to 32 MHz with the RL78 CPU core delivering 44 DMIPS. Its high-speed on-chip oscillator achieves ±1.0% accuracy across 1.8–5.5 V supply and −20 to +85°C ambient, enabling deterministic real-time execution without external crystal dependency in many applications.
Does the R5F104MFGFA#30 support in-system programming and secure firmware updates?
Yes, the R5F104MFGFA#30 supports self-programming with boot swapping and flash shield window protection. It enables secure firmware updates by validating new code in a secondary flash bank before atomic bank switching - preventing corruption during power loss or interrupted writes.
How does the R5F104MFGFA#30 manage ultra-low-power operation in battery-powered applications?
The R5F104MFGFA#30 achieves 0.60 μA in STOP mode with only RTC and LVD active, and 66 μA/MHz in active mode. Its SNOOZE mode permits background data flash rewriting while CPU is halted, and its 14-level LVD supports adaptive brown-out response - collectively extending battery life in remote sensors and portable equipment.
What analog peripherals are integrated into the R5F104MFGFA#30, and how are they calibrated?
The R5F104MFGFA#30 integrates a 10-bit A/D converter with 16 input channels, internal 1.45 V reference voltage, and on-chip temperature sensor. Factory calibration data for ADC offset/gain is stored in ROM, and users can perform one-point or two-point calibration using the internal reference to achieve ±1 LSB typical accuracy across temperature.
Is the R5F104MFGFA#30 pin-compatible with other RL78/G14 variants in the same package footprint?
Yes, all RL78/G14 devices in the 80-pin LQFP-0.65 mm package (e.g., R5F104MGFA#30, R5F104MHFA#30) share identical pinout and electrical characteristics. Peripheral enablement is controlled by flash option bytes and register settings - allowing hardware reuse across memory/peripheral variants without PCB redesign.
