Product details
Overview
R7F100GLG2DFA#AA0 from Renesas is a 64-pin, consumer-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 ultra-low power (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), and rich peripherals including 16-bit timers, 12-bit ADC (26 channels), UART/LIN, I²C, SPI, RTC, and watchdog-targeting battery-powered HMI and sensor-edge applications.
For engineers reviewing the R7F100GLG2DFA#AA0 datasheet, R7F100GLG2DFA#AA0 pinout, R7F100GLG2DFA#AA0 application, or R7F100GLG2DFA#AA0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, -40°C to +85°C temperature grade, D-suffix consumer qualification, and support for SNOOZE mode sequencer and ELCL event linking without CPU wake-up.
Technical Context
The R7F100GLG2DFA#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting 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, with STOP wakeup in under 4 µs and SNOOZE sequencer executing up to 32 low-power processes using 21 command types.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between functions, a Data Transfer Controller (DTC) supporting chain transfers, and a Capacitive Touch Sensing Unit (CTSU2L) configurable for self- or mutual-capacitance operation-enabling touch interfaces with minimal firmware overhead and no external components.

FAQ
What is the operating temperature range for the R7F100GLG2DFA#AA0?
The R7F100GLG2DFA#AA0 is qualified for consumer applications with an operating ambient temperature range of -40°C to +85°C. This is indicated by the "D" suffix in the part number and confirmed in the RL78/G23 datasheet section 1.1. The device uses standard commercial-grade packaging and thermal characterization.
Does the R7F100GLG2DFA#AA0 support capacitive touch sensing?
Yes, the R7F100GLG2DFA#AA0 integrates the CTSU2L capacitive touch sensing unit. It supports both self-capacitance (up to 32 keys on single pins) and mutual-capacitance (up to 64 keys in 8×8 matrix) configurations, with built-in noise cancellation and no external components required-fully documented in the RL78/G23 User's Manual Chapter 34.
What package type does the R7F100GLG2DFA#AA0 use?
The R7F100GLG2DFA#AA0 uses a 64-pin LFQFP package with 0.50-mm pitch, 10 × 10 mm body size, and lead-free/RoHS compliance. The "#AA0" suffix denotes tray packaging. This matches the "FB" package code in Renesas' part numbering scheme and is verified in Table 1-1 of the R01DS0395EJ0140 datasheet.
How much flash and RAM does the R7F100GLG2DFA#AA0 have?
The R7F100GLG2DFA#AA0 contains 512 KB of code flash memory, 8 KB of data flash memory, and 48 KB of on-chip RAM. These values are explicitly listed in the memory matrix on page 3 of the RL78/G23 datasheet (R01DS0395EJ0140) and correspond to the "L" (512 KB), "G" (48 KB), and fixed 8 KB data flash coding in the part number structure.
Is the R7F100GLG2DFA#AA0 pin-compatible with other RL78/G23 variants?
No-pin compatibility is strictly limited to other 64-pin LFQFP-0.5 mm variants within the RL78/G23 family, such as R7F100GLL2DFA#AA0 or R7F100GLF2DFA#AA0. The R7F100GLG2DFA#AA0 shares identical pin count, pitch, and mechanical outline with those parts, but functional pin assignments (e.g., peripheral multiplexing) may differ based on memory size and feature enablement per datasheet Table 1-3.
