Product details
Overview
R5F101LCDFA#V0 from Renesas is a 64-pin LQFP-0.65mm, 16-bit RL78/G13 microcontroller with 128 KB flash, 12 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), 16-channel 16-bit timers, 12-bit RTC, 10-bit 26-channel ADC, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101LCDFA#V0 datasheet, R5F101LCDFA#V0 pinout, R5F101LCDFA#V0 application, or R5F101LCDFA#V0 equivalent, key selection criteria include its 64-pin LQFP package, absence of on-chip data flash, industrial-grade -40°C to +85°C operation (D-grade), integrated RTC with calendar/alarm, and support for background data flash programming via external library.
Technical Context
The R5F101LCDFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz) and 1 MB address space. It integrates dual-clock domains: high-speed main system clock (up to 32 MHz) and independent subsystem clock (32.768 kHz) for RTC/LVD operation during ultra-low-power STOP mode.
Its peripheral set includes 2–4 channel DMA, 16-bit × 16-bit multiply-accumulate unit, 3–10 channel I²C/Simplified I²C, 2–4 channel UART (LIN-capable), and 2–8 channel CSI - all configurable without external components. The 26-channel 10-bit ADC supports internal 1.45 V reference and temperature sensing, with conversion times as low as 1.2 μs per sample.

FAQ
What is the maximum operating frequency and power consumption of the R5F101LCDFA#V0?
The R5F101LCDFA#V0 operates up to 32 MHz (41 DMIPS) with typical active current of 66 μA/MHz. In STOP mode with only RTC and LVD enabled, it draws just 0.57 μA - verified per R01DS0131EJ0380 Rev.3.80 datasheet Section 1.1. This makes R5F101LCDFA#V0 ideal for battery-powered industrial sensors requiring multi-year runtime.
Does the R5F101LCDFA#V0 include on-chip data flash memory?
No, the R5F101LCDFA#V0 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number (per Figure 1-1, Note 2), it provides 128 KB code flash and 12 KB RAM only. For nonvolatile parameter storage, external EEPROM or serial flash must be used - unlike the R5F100LCDFA#V0 variant which includes 4 KB data flash.
What package type and pin count does the R5F101LCDFA#V0 use?
The R5F101LCDFA#V0 uses a 64-pin LQFP package with 0.65 mm pitch, conforming to JEDEC standard PLQP0064JA-A footprint. Its #V0 suffix confirms tray packaging for surface-mount assembly. This package supports full peripheral access including all 26 ADC channels, multiple UART/I²C interfaces, and 16-bit timers - validated in Table 1-1 (Page 10) of the RL78/G13 datasheet.
What industrial temperature grade does the R5F101LCDFA#V0 support?
The R5F101LCDFA#V0 is rated for industrial operation from -40°C to +85°C (D-grade), as confirmed by its part number suffix "D" and Table 1-1 listing under "Fields of Application = D". It is not qualified for the extended -40°C to +105°C (G-grade) range. This makes R5F101LCDFA#V0 suitable for factory automation, HVAC controls, and other industrial environments within standard ambient limits.
Which debug interface does the R5F101LCDFA#V0 support, and how is it implemented?
The R5F101LCDFA#V0 supports single-wire debug (SWD) via the TOOLRxD pin (P11), integrated into its on-chip debug circuitry. No external debug probe is required beyond a standard SWD/JTAG adapter. This interface enables full flash programming, breakpoint setting, and real-time register inspection - documented in Section 1.1 "On-chip debug function" and pin configuration diagrams of the R5F101LCDFA#V0 datasheet.
