Product details
Overview
R7F100GEF2DNP#HA0 from Renesas is a 40-pin HWQFN-packaged RL78/G23 16-bit MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), 16-bit TAU timers, RTC, 12-bit ADC (26 channels), and dual 8-bit DACs - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GEF2DNP#HA0 datasheet, R7F100GEF2DNP#HA0 pinout, R7F100GEF2DNP#HA0 application, or R7F100GEF2DNP#HA0 equivalent, key selection criteria include its 40-pin HWQFN-0.5mm package, -40°C to +85°C consumer-grade temperature range, integrated CTSU2L for self/mutual-capacitance touch, and SNOOZE mode sequencer enabling CPU-free low-power periodic sensing.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode) and supports multiply/divide/MAC instructions. Its memory subsystem includes 128 KB on-chip code flash (2 KB block size, security lockable), 8 KB background-operable data flash (1M rewrite cycles), and 16 KB SRAM with 210-nA data retention.
Peripherals are orchestrated via event-driven logic: ELCL routes signals between peripherals without CPU intervention; DTC handles memory transfers triggered by interrupts; SMS executes up to 32 low-power sequenced operations (e.g., ADC sampling → compare → GPIO toggle) while CPU, flash, and RAM remain powered down.

FAQ
What is the maximum operating frequency and corresponding current draw for R7F100GEF2DNP#HA0?
R7F100GEF2DNP#HA0 operates up to 32 MHz using the high-speed on-chip oscillator (±1.0% accuracy). At this frequency, its typical active current is 41 µA per MHz - resulting in ~1.3 mA total at full speed with all peripherals active. This value assumes VDD = 3.3 V and TA = 25°C per the RL78/G23 datasheet Rev.1.40.
Does R7F100GEF2DNP#HA0 support hardware debugging, and what interface is used?
Yes, R7F100GEF2DNP#HA0 supports on-chip debugging via the dedicated TOOL0 (pin 1) and TOOLRxD/TOOLTxD (pins 25/24) signals. These connect to Renesas E2 or E2 Lite debuggers using the standard SWD-like interface defined in the RL78/G23 User's Manual, enabling full breakpoint, watchpoint, and flash programming capability.
How many capacitive touch channels can R7F100GEF2DNP#HA0 support in mutual-capacitance mode?
R7F100GEF2DNP#HA0 supports up to 64 keys in mutual-capacitance mode using an 8 × 8 electrode matrix driven by its CTSU2L unit. This configuration requires 16 dedicated pins (8 for X-lines, 8 for Y-lines) and is explicitly validated for the 40-pin HWQFN package in the RL78/G23 datasheet Section 1.6.
What is the endurance rating and access method for the data flash memory in R7F100GEF2DNP#HA0?
R7F100GEF2DNP#HA0 includes 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical). It supports background operation (BGO): CPU executes code from main flash while data flash is rewritten, enabled via the FLMCR register and managed through the Flash Control Module API in the Renesas FDL library.
Is R7F100GEF2DNP#HA0 pin-compatible with other RL78/G23 40-pin variants like R7F100GEG2DNP#HA0?
Yes, R7F100GEF2DNP#HA0 is fully pin-compatible with all other RL78/G23 40-pin HWQFN variants including R7F100GEG2DNP#HA0 and R7F100GEH2DNP#HA0. The pin functions, electrical characteristics, and package dimensions (6 × 6 mm, 0.50-mm pitch) are identical - only memory size and temperature grade differ between these orderable part numbers.
