Product details
Overview
R7F100GFG2DFP#UA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UART, I²C, and CSI for embedded control in battery-powered industrial and consumer devices.
For engineers reviewing the R7F100GFG2DFP#UA0 datasheet, R7F100GFG2DFP#UA0 pinout, R7F100GFG2DFP#UA0 application, or R7F100GFG2DFP#UA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40 to +85°C temperature grade (D-field), 256 KB flash/24 KB RAM memory configuration, CTSU2L capacitive sensing support, and SNOOZE mode sequencer for autonomous low-power sensor polling.
Technical Context
The R7F100GFG2DFP#UA0 implements the RL78 CPU core with a 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 ultra-low-speed mode). Its SNOOZE mode sequencer (SMS) executes up to 32 predefined commands-including ADC sampling, comparison, and conditional branching-without CPU, RAM, or flash activation, enabling deterministic sub-µA wake-up-triggered sensing cycles.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers across UART, ADC, and timer sources, and a capacitive sensing unit (CTSU2L) configurable for self-capacitance (up to 32 keys) or mutual-capacitance (8×8 matrix, up to 64 keys) operation at VDD = 1.8–5.5 V.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GFG2DFP#UA0?
The R7F100GFG2DFP#UA0 operates at up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy. At this frequency and VDD = 3.3 V, typical active current is 41 µA per MHz - resulting in ~1.31 mA total at full speed. In STOP mode, current drops to 210 nA for 4 KB RAM retention, verified per R01DS0395EJ0140 datasheet Section 1.1.
Does the R7F100GFG2DFP#UA0 support capacitive touch sensing, and what configurations are available?
Yes, the R7F100GFG2DFP#UA0 integrates the CTSU2L capacitive sensing unit. It supports self-capacitance mode (up to 32 keys, one pin per key) and mutual-capacitance matrix mode (up to 64 keys, 8×8 configuration). Operation is specified for VDD = 1.8–5.5 V, and dedicated pins like P30 (TSCAP) and P31 (TS01) are assigned for this function per datasheet Table 1-5.
What debug and programming interfaces does the R7F100GFG2DFP#UA0 provide?
The R7F100GFG2DFP#UA0 supports on-chip debugging via the single-pin TOOL0 interface (pin P40) and SWD-compatible serial wire debug. It includes full self-programming capability with boot swapping and flash shield window protection. No external debugger hardware is required beyond a standard Renesas E2 or E2 Lite emulator connected to TOOL0 and RESET.
How many UART, I²C, and CSI channels does the R7F100GFG2DFP#UA0 support?
The R7F100GFG2DFP#UA0 supports up to 6 UARTA channels (including LIN-bus compliant operation), up to 10 I²C/Simplified I²C channels, and up to 8 CSI (equivalent to SPI) channels. Channel count is fixed per device variant; the R7F100GFG2DFP#UA0 implements all 6 UARTA, 10 I²C, and 8 CSI instances as confirmed in Section 1.1 "Features" and Table 1-1 of R01DS0395EJ0140.
What is the purpose and capability of the SNOOZE mode sequencer (SMS) in the R7F100GFG2DFP#UA0?
The SNOOZE mode sequencer (SMS) in the R7F100GFG2DFP#UA0 executes up to 32 preloaded commands-including ADC conversions, value comparisons, and conditional jumps-without waking the CPU, flash, or RAM. It enables autonomous, ultra-low-power sensor polling cycles (e.g., periodic temperature reads with threshold check), reducing average system current to sub-microamp levels while maintaining deterministic response latency.
