Renesas R5F100FFGFP#V0

Overview

R5F100FFGFP#V0 from Renesas is a 44-pin LQFP-44, 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, 4 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode). It integrates UART, I²C, CSI, 16-bit timers, 10-bit ADC (12 channels), RTC, and on-chip debug for embedded control in battery-powered industrial sensors and smart home devices.

For engineers reviewing the R5F100FFGFP#V0 datasheet, R5F100FFGFP#V0 pinout, R5F100FFGFP#V0 application, or R5F100FFGFP#V0 equivalent, key selection criteria include its 44-pin LQFP package, -40°C to +105°C industrial temperature grade (G suffix), integrated data flash with 1M rewrite cycles, background operation capability, and support for SNOOZE/STOP/HALT low-power modes in resource-constrained designs.

Technical Context

The R5F100FFGFP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features dual-voltage operation (1.6–5.5 V), on-chip power-on-reset and 14-level voltage detector, and DMA controller with 4 channels for efficient peripheral-to-memory transfers.

Its timing subsystem includes one real-time clock with calendar/alarm/correction functions, one watchdog timer with dedicated low-speed oscillator, and up to 16 × 16-bit timers - including interval timer, input capture, output compare, and PWM generation - enabling precise event scheduling and motor/sensor interface control without CPU overhead.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100FFGFP#V0?

The R5F100FFGFP#V0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, enabling responsive real-time control in applications such as motor drives and sensor fusion. The core maintains deterministic timing across all supported clock sources, including the 32.768 kHz subsystem oscillator.

Does the R5F100FFGFP#V0 support in-system programming and secure firmware updates?

Yes, the R5F100FFGFP#V0 supports full in-system programming via on-chip debug interface and includes boot swap functionality in its flash memory controller. This allows seamless firmware updates by loading new code into a secondary bank while the primary bank remains active, then atomically switching execution - preventing corruption during power loss. Flash shield window and block erase prohibition further enhance security.

How many analog input channels does the R5F100FFGFP#V0 provide, and what ADC resolution is supported?

The R5F100FFGFP#V0 integrates a 10-bit successive approximation ADC with 12 configurable analog input channels. It supports both single-ended and differential measurement modes, and includes an internal 1.45 V reference voltage source. The ADC operates across the full 1.6–5.5 V supply range, enabling accurate sensor interfacing without external reference components in most industrial and consumer applications.

What low-power modes are available on the R5F100FFGFP#V0, and what is the lowest current consumption achievable?

The R5F100FFGFP#V0 offers HALT, STOP, and SNOOZE low-power modes. In HALT mode with only RTC and LVD active, it draws just 0.57 μA at 25°C. STOP mode consumes 0.73 μA, and SNOOZE mode draws 1.2 μA while allowing selected peripherals (e.g., UART, ADC) to operate autonomously. All modes retain RAM contents and support wake-up via interrupts or reset events.

Is the R5F100FFGFP#V0 pin-compatible with other RL78/G13 family members in the same package?

Yes, the R5F100FFGFP#V0 is pin-compatible with all other RL78/G13 variants in the 44-pin LQFP-44 package (e.g., R5F100FGAFP#V0, R5F101FFAFP#V0), sharing identical pin assignments, electrical characteristics, and peripheral mappings. This enables drop-in memory or temperature-grade upgrades without PCB redesign, provided the target variant's flash/RAM configuration and operating grade meet system requirements.
