Product details
Overview
R7F100GLK3CFA#AA0 from Renesas is a 64-pin, industrial-grade RL78/G23 16-bit MCU with 512 KB code flash, 8 KB data flash, and 48 KB RAM, operating from 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and rich mixed-signal peripherals including 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and SNOOZE mode sequencer - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GLK3CFA#AA0 datasheet, R7F100GLK3CFA#AA0 pinout, R7F100GLK3CFA#AA0 application, or R7F100GLK3CFA#AA0 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, -40°C to +105°C temperature grade, 512 KB flash/48 KB RAM memory configuration, and support for capacitive touch, UARTA/LIN, IICA, and hardware event linking via ELCL.
Technical Context
The R7F100GLK3CFA#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes - the latter enabling ultra-low-power autonomous peripheral sequencing without CPU involvement.
Peripheral integration centers on the Event Link Controller (ELCL) for flexible signal routing between functions, the Capacitive Touch Sensing Unit (CTSU2L) supporting self- and mutual-capacitance methods, and the Data Transfer Controller (DTC) with chain transfer for efficient memory-to-peripheral DMA operations - all coordinated under a single-voltage 1.6–5.5 V supply.

FAQ
What is the maximum operating frequency of the R7F100GLK3CFA#AA0?
The R7F100GLK3CFA#AA0 supports a maximum CPU operating frequency of 32 MHz using the high-speed on-chip oscillator. This yields a minimum instruction execution time of 0.03125 µs. The device also supports lower-frequency clock sources including 32.768 kHz for RTC and ultra-low-power operation, with automatic clock switching managed by the system clock control circuitry.
Does the R7F100GLK3CFA#AA0 support LIN bus communication?
Yes, the R7F100GLK3CFA#AA0 supports LIN bus communication through its UARTA peripheral, which is explicitly designed to meet LIN 2.2 and SAE J2602 specifications. UARTA channel 1 (P00/P01) is commonly used for LIN physical layer interfacing, and the MCU includes dedicated LIN-specific features such as auto-sync detection, break field generation, and checksum calculation.
What package type and pin count does the R7F100GLK3CFA#AA0 use?
The R7F100GLK3CFA#AA0 uses a 64-pin plastic LQFP package with 0.65-mm pitch (Renesas code PLQP0064JA-A). It is rated for industrial temperature range (-40°C to +105°C) and shipped in trays (#AA0 packaging specification). This package provides full access to all major peripherals including CTSU2L, multiple UART/I²C/SPI channels, and 26-channel ADC inputs.
How much data flash memory is integrated into the R7F100GLK3CFA#AA0?
The R7F100GLK3CFA#AA0 integrates 8 KB of data flash memory, rated for 1,000,000 write/erase cycles (typical). This memory supports background operation (BGO), allowing program execution from code flash while simultaneously rewriting data flash - essential for reliable parameter storage, firmware update staging, and field calibration data retention in the R7F100GLK3CFA#AA0.
Can the R7F100GLK3CFA#AA0 operate from a single 1.8 V supply?
Yes, the R7F100GLK3CFA#AA0 operates across a supply voltage range of 1.6 V to 5.5 V, fully supporting 1.8 V nominal operation. At 1.8 V, all core functions-including 32 MHz operation (with ±1.0% accuracy), 12-bit ADC, CTSU2L, and data flash programming-remain functional per the electrical characteristics table in the R01DS0395EJ0140 datasheet.
