It targets battery-powered industrial sensors and smart metering interfaces requiring deterministic real-time control.
For engineers reviewing the R5F101FAA100FP#V0 datasheet, R5F101FAA100FP#V0 pinout, R5F101FAA100FP#V0 application, or R5F101FAA100FP#V0 equivalent, key selection criteria include its integrated 10-bit ADC (24 channels), RTC with calendar/alarm, LIN-capable UARTs, and support for SNOOZE mode wake-up via peripheral interrupts - all critical for energy-constrained embedded systems.
Technical Context
The R5F101FAA100FP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz), enabling dynamic clock scaling across performance and ultra-low-power states. Its memory subsystem includes 96 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 8 KB on-chip RAM.
Peripheral integration includes up to 16× 16-bit timers, 1× real-time clock with 99-year calendar, 1× watchdog timer, 3× I²C/Simplified I²C channels, 2× UART/LIN interfaces, 2× CSI (SPI-compatible) channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all accessible within the 44-pin LQFP package footprint.

FAQ
What is the maximum operating frequency of the R5F101FAA100FP#V0?
The R5F101FAA100FP#V0 supports a maximum CPU clock frequency of 32 MHz using the high-speed on-chip oscillator. This yields 41 DMIPS performance and a minimum instruction execution time of 0.03125 μs. The oscillator accuracy is ±1.0% over VDD = 1.8–5.5 V and TA = –20 to +85°C, as specified in the R01DS0131EJ0380 datasheet.
Does the R5F101FAA100FP#V0 include data flash memory?
No, the R5F101FAA100FP#V0 does not include data flash memory. Per Renesas part numbering convention (Section 1.2), the "101" prefix indicates no data flash, whereas "100" denotes inclusion of 4–8 KB data flash. This variant relies on code flash for non-volatile storage or external EEPROM for frequent write cycles.
What package type and pin count does the R5F101FAA100FP#V0 use?
The R5F101FAA100FP#V0 uses a 44-pin LQFP package (10 × 10 mm, 0.8-mm pitch), indicated by the "FP" suffix and "44" position in the part number decode. The "#V0" denotes tray packaging. This package is RoHS-compliant and compatible with standard surface-mount assembly processes.
Can the R5F101FAA100FP#V0 operate from a 1.8 V supply?
Yes, the R5F101FAA100FP#V0 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supply. At 1.8 V, the maximum operating frequency is reduced per the voltage-frequency specification curve; full 32 MHz operation requires ≥2.4 V. All peripherals, including ADC and RTC, remain functional across the full voltage range.
How many analog input channels does the R5F101FAA100FP#V0 support?
The R5F101FAA100FP#V0 supports up to 24 analog input channels for its 8/10-bit A/D converter. Channel mapping depends on pin configuration; for the 44-pin LQFP package, ANI0–ANI7 are assigned to P20–P27, with additional channels available on other port pins as detailed in the RL78/G13 pin function table (R01DS0131EJ0380, Page 13+).
