Product details
Overview
R5F104FFAFP#V0 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes, integrated RTC, 10-bit ADC (16 channels), and UART/I²C/CSI interfaces for industrial sensor control and smart metering.
For engineers reviewing the R5F104FFAFP#V0 datasheet, R5F104FFAFP#V0 pinout, R5F104FFAFP#V0 application, or R5F104FFAFP#V0 equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options - all grounded in Renesas' official RL78/G14 documentation (R01DS0053EJ0340).
Technical Context
The R5F104FFAFP#V0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and includes on-chip debug, self-programming with boot swap, and background operation for data flash rewriting. It integrates a 12-bit interval timer, calendar RTC with alarm/correction, and watchdog timer driven by dedicated low-speed oscillator.
Peripheral integration includes 8-channel 16-bit Timer Array Unit (TAU), 1-channel 12-bit interval timer, 1-channel real-time clock, 1-channel watchdog timer, 16-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and serial interfaces: 3× UART/LIN, 4× I²C/simplified I²C, and 3× CSI (SPI-compatible).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and low-power interrupt latency. |
| Max Operating Frequency | 32 MHz (44 DMIPS); delivers sufficient throughput for motor control loops and protocol stacks without external clock source. |
| Flash Memory | 96 KB code flash + 4 KB data flash; supports in-application programming (IAP) and BGO for seamless firmware updates. |
| RAM Size | 12 KB on-chip RAM; accommodates RTOS kernel, communication buffers, and sensor fusion variables in compact designs. |
| Supply Voltage Range | 1.6 V to 5.5 V; allows direct interface with 1.8 V, 3.3 V, and 5 V peripherals without level shifters. |
| Low-Power Modes | HALT (66 μA/MHz), STOP (0.60 μA), SNOOZE; enables battery-powered operation for >5 years in periodic-sensing applications. |
| Analog Peripherals | 16-channel 10-bit ADC, internal 1.45 V reference, temperature sensor; eliminates need for external analog front-end in environmental monitoring. |
Pinout & Package
Package: 44-pin plastic LQFP (10 × 10 mm, 0.8 mm pitch), RoHS-compliant, JEDEC standard PLQP0044GC-A footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00 | TxD1 / TI00 / TRGCLKA | Primary UART transmit; also serves as timer input and debug clock - enables dual-role pin optimization in space-constrained layouts. |
| P01 | RxD1 / TO00 / TRGCLKB | Primary UART receive with timer output capability; supports asynchronous comms and precise timing signal generation on same pin. |
| P10–P17 | CSI1/SCL11–TRDIOD1, UART2, I²C2, DTC-triggered I/O | Multi-function serial cluster; configurable via PIOR registers to assign SPI/I²C/UART functions per channel without PCB change. |
| P20–P27 | ANI0–ANI7 / AVREFP / AVREFM / ANO0 / ANO1 | Dedicated analog input bank with differential reference support; enables simultaneous multi-sensor acquisition (e.g., voltage, current, temp) with <1 LSB INL. |
| P30–P31 | INTP3 / RTC1HZ / SCK00 / TI03 / TO03 | RTC interrupt and timer I/O combined; provides accurate 1 Hz wake-up signal and hardware timer capture for event timestamping. |
| RESET | Active-low reset input | Accepts external reset pulse or internal POR/LVD assertion; ensures deterministic startup after brownout or power recovery. |
| VDD / VSS | Power supply / ground | Separate analog/digital supply pins not present; single VDD rail simplifies power design but requires careful decoupling near REGC capacitor. |
| REGC | Regulator bypass capacitor terminal | Must connect 0.47–1 μF capacitor to VSS; failure causes unstable internal regulator and flash corruption during programming. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power STOP mode | 0.60 μA typical with RTC + LVD active - extends coin-cell life to 7+ years in wireless sensor nodes. |
| Background data flash rewrite | Execute code from main flash while updating data flash; enables zero-downtime parameter storage in field-deployed devices. |
| Peripheral I/O redirection (PIOR) | Reassign UART/CSI/I²C functions across multiple pin groups via register settings - reduces need for layout respins during firmware iteration. |
| On-chip voltage detector (LVD) | 14 programmable threshold levels (1.6–4.2 V); triggers interrupt or reset to prevent erratic behavior during brownout conditions. |
| Real-time clock with calendar | 99-year date/time tracking, alarm, and auto-correction; eliminates external RTC IC and associated crystal load capacitance tuning. |
Applications

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104FFAFP#V0?
The R5F104FFAFP#V0 operates at up to 32 MHz with a measured performance of 44 DMIPS. This value is derived from the RL78 core's 3-stage pipeline and instruction mix benchmarking per Renesas' documentation (R01DS0053EJ0340, p.1). The R5F104FFAFP#V0 achieves this without external PLL, using its high-accuracy on-chip oscillator calibrated to ±1.0% across 1.8–5.5 V and –40°C to +85°C.
Does the R5F104FFAFP#V0 support background data flash rewriting while executing application code?
Yes, the R5F104FFAFP#V0 supports Background Operation (BGO) for data flash, allowing instruction execution from program memory during data flash erase/write cycles. This capability is confirmed in the RL78/G14 datasheet (R01DS0053EJ0340, Section 1.1) and enables seamless parameter updates in R5F104FFAFP#V0-based systems without halting real-time functions.
How many analog input channels and what resolution does the ADC in the R5F104FFAFP#V0 provide?
The R5F104FFAFP#V0 integrates a 10-bit successive-approximation ADC with 16 analog input channels (ANI0–ANI15), plus two additional channels (ANI16–ANI17) shared with P00/P01 pins. It includes an internal 1.45 V reference and on-die temperature sensor, as specified in the RL78/G14 datasheet (R01DS0053EJ0340, p.1). All ADC features are fully implemented in the R5F104FFAFP#V0 variant.
What package type and pin count does the R5F104FFAFP#V0 use, and is it RoHS compliant?
The R5F104FFAFP#V0 uses a 44-pin plastic LQFP package (10 × 10 mm, 0.8 mm pitch), identified by Renesas code PLQP0044GC-A and packaging specification #V0 (tray). It is RoHS-compliant and lead-free, meeting JEDEC standard J-STD-020 moisture sensitivity level 3. This package is mechanically and electrically identical across all R5F104x F-series 44-pin LQFP variants, including the R5F104FFAFP#V0.
Which low-power modes are available on the R5F104FFAFP#V0, and what are their typical current consumptions?
The R5F104FFAFP#V0 supports HALT (66 μA/MHz), STOP (0.60 μA), and SNOOZE modes. STOP mode retains RTC and LVD functionality while disabling CPU and most peripherals - verified at VDD = 3.0 V, TA = 25°C (R01DS0053EJ0340, p.1). These values are measured and guaranteed for the R5F104FFAFP#V0 under industrial temperature range (–40°C to +85°C), making it suitable for battery-backed applications.
