Renesas R5F100FAGFP#10

Overview

R5F100FAGFP#10 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6–5.5 V across –40°C to +105°C industrial temperature range. It integrates RTC, 10-bit ADC (16 channels), UART/SPI/I²C interfaces, 16-bit timers, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for battery-powered sensor nodes and industrial control.

For engineers reviewing the R5F100FAGFP#10 datasheet, R5F100FAGFP#10 pinout, R5F100FAGFP#10 application, or R5F100FAGFP#10 equivalent, key selection criteria include industrial-grade temperature support, integrated data flash with 1M rewrite cycles, background operation during program execution, on-chip debug, and hardware multiplier/divider for real-time signal processing in space-constrained embedded designs.

Technical Context

The R5F100FAGFP#10 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-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.

Its peripheral set includes up to 4 UART/LIN channels, 8 CSI (SPI-compatible) channels, 10 I²C channels, 16× 16-bit timers, 12-bit interval timer, calendar RTC with alarm/correction, and 10-bit ADC with internal 1.45 V reference and temperature sensor-enabling autonomous timing, communication, and analog sensing without external components.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the R5F100FAGFP#10?

The R5F100FAGFP#10 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS (Dhrystone MIPS) at that frequency. This performance level is achieved through the RL78 CPU core's 3-stage pipeline architecture and optimized instruction set, enabling efficient real-time control tasks such as motor commutation and sensor fusion without external co-processors.

Does the R5F100FAGFP#10 support in-system programming and secure firmware updates?

Yes, the R5F100FAGFP#10 supports full in-system programming via its on-chip debug interface and includes flash shield window and block erase prohibition features. These capabilities allow secure firmware updates in the field while preventing unauthorized access to or modification of protected code sections-critical for certified industrial and automotive deployments.

How many analog input channels does the R5F100FAGFP#10 provide, and what ADC resolution is supported?

The R5F100FAGFP#10 provides 16 analog input channels (ANI0–ANI15) with a 10-bit successive approximation ADC. It includes an internal 1.45 V reference voltage and supports differential measurement modes using AVREFP/AVREFM pins-enabling accurate ratiometric readings from resistive sensors and direct temperature monitoring without external components.

What low-power modes are available on the R5F100FAGFP#10, and what is the lowest achievable current draw?

The R5F100FAGFP#10 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year operation on primary batteries in wireless sensor and metering applications where periodic wake-up is required.

Is the R5F100FAGFP#10 pin-compatible with other RL78/G13 variants in the same LQFP-44 package?

Yes, the R5F100FAGFP#10 shares identical pinout and electrical characteristics with all other RL78/G13 devices in the 44-pin LQFP-0.8 mm pitch package (e.g., R5F100FGAFP#V0, R5F100FHGFP#10), including identical I/O mapping, power pin locations, and debug interface pins-allowing drop-in replacement within the same memory and temperature grade family.
