Product details
Overview
R5F104BCGFP#V0 from Renesas is a 32-bit RL78/G14 microcontroller with 16 KB flash memory, 2.5 KB RAM, and 48-pin LFQFP (0.5 mm pitch) package, operating from 1.6 V to 5.5 V. It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F104BCGFP#V0 datasheet, R5F104BCGFP#V0 pinout, R5F104BCGFP#V0 application, or R5F104BCGFP#V0 equivalent, key selection criteria include its 16 KB flash size, -40°C to +105°C industrial temperature grade (G suffix), LFQFP-48 footprint, integrated data flash (4 KB), and support for SNOOZE mode low-power operation.
Technical Context
The R5F104BCGFP#V0 implements the RL78 CPU core with CISC architecture and 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). It includes on-chip debug, self-programming with boot swap, and background operation for data flash rewriting.
Peripheral integration includes Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, real-time clock with calendar/alarm, watchdog timer, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention - enabling deterministic low-latency response in motor control and PLC I/O modules.

It supports background operation (BGO), allowing program execution from main flash while rewriting data flash - a key capability used in firmware-over-the-air updates and calibrated sensor storage within the R5F104BCGFP#V0.
What package type and pin count does the R5F104BCGFP#V0 use, and is it RoHS compliant?
The R5F104BCGFP#V0 uses a 48-pin LFQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. It is RoHS compliant and lead-free per JEDEC J-STD-609, meeting industrial environmental standards. The #V0 suffix indicates tray packaging, and the G suffix confirms -40°C to +105°C industrial temperature qualification for the R5F104BCGFP#V0.
How does the R5F104BCGFP#V0 support low-power operation in battery-powered applications?
The R5F104BCGFP#V0 achieves ultra-low power via HALT, STOP, and SNOOZE modes - consuming just 66 μA/MHz active and 0.60 μA in STOP mode with RTC + LVD active.
