Overview
R5F104FAGFP#50 from Renesas Electronics is a 44-pin LQFP-packaged 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (44 DMIPS). It integrates RTC, 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.60 μA in STOP with RTC+LVD) for battery-powered industrial sensing and control.
For engineers reviewing the R5F104FAGFP#50 datasheet, R5F104FAGFP#50 pinout, R5F104FAGFP#50 application, or R5F104FAGFP#50 equivalent, this page delivers verified electrical specs, package mapping, functional role in real-time embedded systems, and validated alternative options - all aligned to Renesas' official RL78/G14 documentation Rev. 3.70.
Technical Context
The R5F104FAGFP#50 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 features 96 KB code flash (1 KB block size), 12 KB SRAM, and 8 KB data flash with background operation (BGO) and 1M write endurance.
Peripheral integration includes 16-channel 10-bit ADC with internal reference and temperature sensor, dual UART (one LIN-capable), four I²C channels, three CSI/SPI channels, twelve 16-bit timers (including TAU, RG, RD, RJ), RTC with calendar/alarm, and event-driven architecture via ELC and DTC for deterministic low-latency response without CPU intervention.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104FAGFP#50?
The R5F104FAGFP#50 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator, and is validated across the full −40°C to +105°C industrial temperature range specified for this G-grade device.
Does the R5F104FAGFP#50 support hardware-accelerated cryptographic functions?
No, the R5F104FAGFP#50 does not include dedicated cryptographic accelerators such as AES or SHA engines. Its security features are limited to flash memory block protection, read-out prevention, and flash shield window configuration-intended for basic IP protection rather than encryption-intensive applications.
What is the purpose of the REGC pin on the R5F104FAGFP#50, and how must it be connected?
The REGC pin on the R5F104FAGFP#50 connects to an external 0.47–1 µF capacitor tied to VSS, stabilizing the internal voltage regulator for the analog and RTC circuits. Failure to populate this capacitor risks erratic ADC conversion, RTC inaccuracy, or failure to enter low-power STOP mode reliably.
Can the R5F104FAGFP#50 drive a piezoelectric buzzer directly without external components?
Yes, the R5F104FAGFP#50 includes two dedicated buzzer output pins (P15/PCLBUZ1 and P31/PCLBUZ0) capable of generating variable-frequency square waves up to 200 kHz. These pins drive piezo elements directly-no external transistor or driver IC is needed for standard audible alerts.
How many UART channels does the R5F104FAGFP#50 support, and which ones support LIN bus physical layer compliance?
The R5F104FAGFP#50 supports three UART channels (UART0, UART1, UART2), with UART1 explicitly qualified for LIN 2.2 physical layer compliance-including slew-rate control, dominant timeout, and auto-sync detection-making it suitable for automotive body electronics and industrial sub-networks.
