Product details
Overview
R5F101LEAFA#30 from Renesas is a 64-pin LQFP-0.65mm, 48 KB flash, 4 KB data flash, 4 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated 10-bit ADC (26 channels), RTC, UART, I²C, and SPI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101LEAFA#30 datasheet, R5F101LEAFA#30 pinout, R5F101LEAFA#30 application, or R5F101LEAFA#30 equivalent, key selection criteria include verified 64-pin LQFP package compatibility, confirmed absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (D suffix), and validated real-time clock + low-voltage detection co-functionality for energy-harvesting designs.
Technical Context
The R5F101LEAFA#30 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), and features 1 MB address space with four 8-bit register banks. It integrates dedicated peripherals including a 12-bit interval timer, calendar-based RTC with alarm/correction, and watchdog timer driven by a dedicated low-speed oscillator.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD with interrupt/reset options, and DMA controller with 2 channels enabling 2-clock transfers between SFR and RAM. Serial interfaces comprise up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all configurable without external transceivers.

FAQ
What is the flash memory configuration of the R5F101LEAFA#30?
The R5F101LEAFA#30 contains 48 KB of on-chip code flash memory and no integrated data flash memory - consistent with the R5F101x series designation. This distinguishes it from the R5F100x series (e.g., R5F100LEAFA#30), which includes 4 KB of data flash. Code flash supports block erase (1 KB), self-programming, and boot-swap functionality for robust firmware updates.
Does the R5F101LEAFA#30 support hardware debugging without external tools?
Yes, the R5F101LEAFA#30 includes a fully functional on-chip debug (OCD) circuit accessible via a single-wire debug (SWD) interface. No external JTAG emulator is required - development and field firmware updates can be performed using standard Renesas E2 studio or CS+ IDE with compatible debug probes such as E2 Lite or E2.
What is the operating temperature range certified for the R5F101LEAFA#30?
The R5F101LEAFA#30 is rated for industrial operation from -40°C to +85°C, indicated by the "D" suffix in its part number family. This rating is validated per JEDEC JESD22-A104 and applies across the full 1.6–5.5 V supply range and all specified operating modes (active, HALT, STOP, SNOOZE).
How many analog input channels does the R5F101LEAFA#30 ADC support?
The R5F101LEAFA#30 integrates a 10-bit successive-approximation ADC with up to 26 configurable analog input channels. Inputs include dedicated AVREFP/AVREFM pins for precision ratiometric measurement, internal temperature sensor, and 1.45 V reference voltage source - all usable without external components.
Is the R5F101LEAFA#30 pin-compatible with other RL78/G13 64-pin variants?
Yes, the R5F101LEAFA#30 shares identical 64-pin LQFP-0.65mm mechanical footprint and pin function mapping with all other RL78/G13 devices in the same package variant (e.g., R5F100LEAFA#30, R5F101LFAFA#30). Pin-to-pin compatibility extends to power, reset, clock, debug, and all peripheral I/O assignments - enabling drop-in replacement within the same memory/peripheral configuration group.
