Product details
Overview
R5F101LEDFA#V0 from Renesas is a 64-pin LQFP-0.65mm, 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +85°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART/I²C/CSI interfaces, and real-time clock for embedded control in metering and sensor nodes.
For engineers reviewing the R5F101LEDFA#V0 datasheet, R5F101LEDFA#V0 pinout, R5F101LEDFA#V0 application, or R5F101LEDFA#V0 equivalent, key selection criteria include its 64-pin LQFP package, absence of on-chip data flash, industrial-grade temperature support, and compatibility with RL78 development tools including CS+ and e² studio - critical for low-power industrial firmware deployment.
Technical Context
The R5F101LEDFA#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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 flash configured in 1 KB blocks and security features like block erase prohibition.
Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and DMA controller with 2 channels enabling 2-clock transfers between SFR and RAM. Peripheral integration covers up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, plus real-time clock with calendar, alarm, and clock correction functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LEDFA#V0 | Includes 4 KB data flash memory; identical flash/RAM/package/temperature grade | Required where EEPROM-like nonvolatile storage is needed for calibration data or event logs | Select when field-updatable configuration storage is mandatory; adds ~$0.15 cost and minor firmware complexity |
| R5F101LEDFB#V0 | Same core/peripherals, but LFQFP-64 (0.5 mm pitch) instead of LQFP-64 (0.65 mm pitch) | Suitable for high-density PCBs where finer pitch improves routing density or reduces board area | Choose only if layout constraints require 0.5 mm pitch; requires requalification of solder process and test fixtures |
Compared with R5F100LEDFA#V0, the R5F101LEDFA#V0 saves board space by omitting data flash while maintaining full code execution capability; versus R5F101LEDFB#V0, it offers broader manufacturing compatibility due to the more widely adopted 0.65 mm LQFP footprint.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101LEDFA#V0?
The R5F101LEDFA#V0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This dual-speed capability allows the R5F101LEDFA#V0 to balance responsiveness and energy efficiency across diverse operational phases.
Does the R5F101LEDFA#V0 include on-chip data flash memory?
No, the R5F101LEDFA#V0 does not include on-chip data flash memory. The "101" in the part number explicitly denotes absence of data flash, distinguishing it from "100" variants like R5F100LEDFA#V0 which integrate 4 KB of data flash. Firmware must use code flash sectors or external EEPROM for nonvolatile parameter storage when implementing the R5F101LEDFA#V0 in production systems.
What package type and pin count does the R5F101LEDFA#V0 use?
The R5F101LEDFA#V0 uses a 64-pin LQFP package with 0.65 mm lead pitch (RENESAS code PLQP0064JA-A), measuring 12 × 12 mm. This package is distinct from the LFQFP-64 (0.5 mm pitch) used by variants such as R5F101LEDFB#V0. The LQFP-64 footprint ensures broad compatibility with standard SMT assembly lines and test equipment.
What is the operating temperature range specified for the R5F101LEDFA#V0?
The R5F101LEDFA#V0 is rated for industrial operation from −40°C to +85°C, indicated by the "D" suffix in its family designation per Renesas documentation. This temperature grade makes it suitable for deployment in factory automation, building controls, and outdoor metering equipment where ambient conditions exceed commercial-grade limits.
Which development tools support firmware development for the R5F101LEDFA#V0?
The R5F101LEDFA#V0 is fully supported by Renesas' CS+ IDE and e² studio, both offering compiler, debugger, and flash programming capabilities. Hardware debugging uses the on-chip debug interface via E1/E20 emulators or the Renesas Flash Programmer tool. Peripheral configuration is assisted by the Smart Configurator plug-in, which generates initialization code for ADC, UART, timers, and other modules in the R5F101LEDFA#V0.
