Product details
Overview
R5F104GCDFB#V0 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (D) 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at –40 to +85°C. It delivers 44 DMIPS at 32 MHz, integrates 16-bit timers (12 channels), 10-bit ADC (16 channels), UART/SPI/I²C interfaces, RTC, and ultra-low-power HALT/STOP/SNOOZE modes for embedded control in metering and sensor nodes.
For engineers reviewing the R5F104GCDFB#V0 datasheet, R5F104GCDFB#V0 pinout, R5F104GCDFB#V0 application, or R5F104GCDFB#V0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, 96 KB code flash with security lock, 12 KB RAM, integrated RTC with calendar/alarm, and support for background data flash rewriting (1M cycles) - all critical for cost-sensitive, low-power industrial firmware updates and real-time monitoring.
Technical Context
The R5F104GCDFB#V0 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 features an event-link controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention and a data transfer controller (DTC) supporting block, repeat, and chain transfers activated by 19–26 interrupt sources.
Its mixed-signal subsystem includes a 10-bit ADC with internal 1.45 V reference and temperature sensor, dual 8-bit DACs (0–VDD output), two comparators with window/high-speed/low-speed modes, and programmable I/O with 6 V-tolerant N-ch open-drain capability - enabling direct interfacing with 1.8/2.5/3.3 V logic and analog sensors without level shifters.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104GCDFB#V0?
The R5F104GCDFB#V0 operates at up to 32 MHz with an 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 ultra-low-speed operation down to 32.768 kHz for RTC and low-power monitoring tasks. This dual-speed capability enables both high-performance computation and extended battery life in the same design.
Does the R5F104GCDFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F104GCDFB#V0 supports full in-system programming via its on-chip debug interface (P50/P51 pins) and includes boot swap functionality plus a flash shield window to prevent unauthorized access to protected code regions. These features enable field firmware updates with rollback safety and intellectual property protection without requiring external programmers.
How many analog input channels and what resolution does the ADC in the R5F104GCDFB#V0 provide?
The R5F104GCDFB#V0 integrates a 10-bit successive-approximation ADC with up to 16 analog input channels (ANI0–ANI18, excluding reserved pins). It includes an internal 1.45 V reference voltage and an on-chip temperature sensor, allowing accurate ratiometric measurements and environmental monitoring without external references or sensors.
What low-power modes are available on the R5F104GCDFB#V0, and what is the lowest current consumption?
The R5F104GCDFB#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.60 μA (typical) at VDD = 1.8–5.5 V and TA = –40 to +85°C. This enables multi-year operation on standard coin-cell batteries in wireless sensor and metering applications.
Is the R5F104GCDFB#V0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 48-pin LFQFP-0.5 mm package (e.g., R5F104GHDFB#V0, R5F104GGDFB#V0) share identical pinouts and electrical characteristics.
