Product details
Overview
R5F100FGAFP#70 from Renesas Electronics 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 V to 5.5 V across -40°C to +85°C industrial temperature range. It integrates RTC, 10-bit ADC (16 channels), UART/LIN, I²C, CSI, 16-bit timers, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F100FGAFP#70 datasheet, R5F100FGAFP#70 pinout, R5F100FGAFP#70 application, or R5F100FGAFP#70 equivalent, key selection criteria include its 44-pin LQFP package with 16-channel analog input capability, integrated LIN physical layer support, background data flash rewriting (1M write cycles), and verified operation at 32 MHz with ±1.0% on-chip oscillator accuracy over full voltage and temperature range.
Technical Context
The R5F100FGAFP#70 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). Its memory map includes 1 MB address space, with dedicated flash shield window and boot swap functionality enabling secure firmware updates.
Power management features include HALT, STOP, and SNOOZE modes, POR, and 14-level LVD with selectable interrupt/reset behavior. Peripheral integration covers 2–4 channel DMA, 16×16/32÷32 multiplier/divider, real-time clock with calendar/alarm/correction, and watchdog timer with independent low-speed oscillator.

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F100FGAFP#70?
The R5F100FGAFP#70 supports up to 32 MHz operation with its high-speed on-chip oscillator, specified at ±1.0% accuracy across VDD = 1.8–5.5 V and TA = −20°C to +85°C. This eliminates external crystal requirements in many applications while maintaining timing integrity for UART, LIN, and ADC sampling clocks. The oscillator can be dynamically switched between 32 MHz and lower frequencies (e.g., 1 MHz, 32.768 kHz) to balance performance and power consumption.
Does R5F100FGAFP#70 support background data flash rewriting while executing application code?
Yes, the R5F100FGAFP#70 supports background operation (BGO) for data flash rewriting. During BGO, the CPU executes instructions from program memory while the flash control unit concurrently erases or writes data flash sectors. This enables seamless parameter updates, firmware staging, or data logging without halting real-time tasks-a key capability confirmed in the R01DS0131EJ0380 datasheet Section 1.1.
How many analog input channels does R5F100FGAFP#70 provide, and what is the ADC resolution?
The R5F100FGAFP#70 integrates a 10-bit successive approximation ADC with 16 analog input channels (ANI0–ANI15), operating across the full 1.6–5.5 V supply range. It also includes an internal 1.45 V reference and temperature sensor, both usable only in HS (high-speed main) mode. Channel selection and conversion triggering are fully software-configurable via SFR registers.
What low-power modes are available in R5F100FGAFP#70, and what is the lowest achievable current draw?
The R5F100FGAFP#70 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD enabled, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current is validated in the datasheet's electrical characteristics table and enables multi-year battery life in intermittent-sensing applications such as wireless environmental monitors.
Is R5F100FGAFP#70 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 44-pin LQFP package-including R5F100FGAFP#70, R5F101FGAFP#70, and R5F100EGAFP#70-share identical pinouts and mechanical footprint. Functional differences (e.g., flash size, data flash presence) do not affect pin assignment or electrical characteristics, allowing drop-in replacement within the same memory/peripheral configuration tier.
