Overview
R5F104MKGFA#30 from Renesas is a 80-pin LQFP-0.65 mm pitch, industrial-grade (−40°C to +85°C) RL78/G14 16-bit MCU with 256 KB flash, 8 KB data flash, 24 KB RAM, 48-channel I/O, and integrated RTC, 10-bit ADC (20 ch), UART/SCI/I²C/CSI interfaces, and ultra-low-power operation (66 μA/MHz active, 0.60 μA in RTC+LVD mode). It targets battery-powered industrial control and sensor nodes requiring deterministic real-time response and long-term firmware stability.
For engineers reviewing the R5F104MKGFA#30 datasheet, R5F104MKGFA#30 pinout, R5F104MKGFA#30 application, or R5F104MKGFA#30 equivalent, this page delivers verified electrical specs, validated package mapping, confirmed peripheral allocation, and peer-validated alternative options - all extracted from Renesas R01DS0053EJ0370 Rev. 3.70 and official ordering documentation.
Technical Context
The R5F104MKGFA#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode), and includes multiply/divide/accumulate instructions. Its memory subsystem integrates 256 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 24 KB SRAM - all accessible within a unified 1 MB address space.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104MKGFA#30?
The R5F104MKGFA#30 operates at up to 32 MHz with a typical active current of 66 μA/MHz, yielding ~2.1 mA at full speed. Its high-accuracy on-chip oscillator supports 64 MHz, but the R5F104MKGFA#30 is factory-configured for 32 MHz maximum operation per its flash density and industrial temperature rating. This balance ensures stable timing and minimal self-heating in enclosed enclosures.
Does the R5F104MKGFA#30 support in-system programming and secure firmware updates?
Yes, the R5F104MKGFA#30 supports full in-system programming via on-chip debug interface and includes flash shield window, block erase prohibition, and boot swapping functionality. These features enable authenticated, fail-safe firmware updates in the field without requiring external programmers - critical for remote industrial assets managed by R5F104MKGFA#30-based controllers.
How many UART/SCI interfaces does the R5F104MKGFA#30 include, and are they LIN-compliant?
The R5F104MKGFA#30 includes four UART/SCI modules, all supporting LIN 2.2 protocol via built-in LIN break detection, sync field generation, and checksum calculation. This enables direct connection to automotive body control modules or industrial LIN sensor networks without external transceivers - a key capability confirmed for the R5F104MKGFA#30 in Renesas R01DS0053EJ0370.
What is the ADC performance specification for the R5F104MKGFA#30 under industrial temperature conditions?
The R5F104MKGFA#30 features a 10-bit successive-approximation ADC with 20 input channels, guaranteed ±2 LSB integral nonlinearity and ±1.5 LSB differential nonlinearity over −40°C to +85°C. It includes internal 1.45 V reference and supports sampling rates up to 1 MS/s - enabling high-fidelity acquisition for motor current sensing and energy metering applications deployed with R5F104MKGFA#30.
Is the R5F104MKGFA#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 (PLQP0080JB-E), including R5F104MKGFA#30, R5F104MLGFA#30, and R5F104MHGFA#30, share identical pinouts and electrical characteristics. This allows drop-in replacement for memory or peripheral scaling - a documented compatibility confirmed in Renesas Table 1-1 and functional descriptions for the R5F104MKGFA#30 family.
