Product details
Overview
R5F101FAAFP#V0 from Renesas is a 44-pin LQFP, 32-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating at 32 MHz with 41 DMIPS performance and ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 10-bit ADC (12 channels), UART/LIN, I²C, SPI, RTC, and watchdog timer for embedded control in industrial sensor nodes and power management systems.
For engineers reviewing the R5F101FAAFP#V0 datasheet, R5F101FAAFP#V0 pinout, R5F101FAAFP#V0 application, or R5F101FAAFP#V0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and support for background data flash rewriting via BGO.
Technical Context

FAQ
What is the flash memory configuration of the R5F101FAAFP#V0?
The R5F101FAAFP#V0 contains 64 KB of code flash memory and no on-chip data flash - confirmed by its "101" family designation indicating data flash omission. It supports 1 KB block erase, self-programming with boot swap, and flash shield window protection. The flash library reserves RAM starting at address FEF00H for rewrite operations.
Does the R5F101FAAFP#V0 support LIN bus communication?
Yes, the R5F101FAAFP#V0 supports LIN 2.2 protocol through its UART peripheral, which includes break detection, sync field handling, and checksum generation. No external transceiver is required for basic LIN slave functionality, though a level-shifting transceiver is needed for physical layer compliance in automotive networks.
What is the operating temperature range for the R5F101FAAFP#V0?
The R5F101FAAFP#V0 is rated for industrial operation from -40°C to +85°C, indicated by the "D" suffix in its full part number family. This grade meets JEDEC JESD22-A108 requirements and is qualified for use in factory automation, building controls, and outdoor metering equipment.
How does the R5F101FAAFP#V0 achieve ultra-low power consumption?
The R5F101FAAFP#V0 achieves 0.57 μA in STOP mode using dedicated low-speed oscillators for RTC and LVD, combined with selective peripheral clock gating and retention of only essential registers. Its 66 μA/MHz active-mode efficiency stems from adaptive voltage regulation and optimized circuit design across the RL78/G13 platform.
Can the R5F101FAAFP#V0 interface directly with 3.3 V or 1.8 V peripherals?
Yes, the R5F101FAAFP#V0 supports different-potential interfaces: I/O pins can be configured for TTL input thresholds and include on-chip pull-up resistors, enabling reliable communication with 1.8 V, 2.5 V, and 3.3 V logic without level shifters - verified across all 44 pins per the RL78/G13 datasheet electrical characteristics table.
