Product details
Overview
R7F100GBF2DFP#BA0 from Renesas is a 32-bit RL78/G23 microcontroller with 128 KB code flash, 16 KB RAM, and 8 KB data flash, 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 (up to 64 keys), and supports industrial temperature range (−40 to +105°C) for embedded control in battery-powered HMI and sensor nodes.
For engineers reviewing the R7F100GBF2DFP#BA0 datasheet, R7F100GBF2DFP#BA0 pinout, R7F100GBF2DFP#BA0 application, or R7F100GBF2DFP#BA0 equivalent, key selection criteria include its LQFP-32 package, 32-pin I/O count, integrated RTC and SNOOZE mode sequencer for autonomous low-power operation, and dual-voltage I/O capability supporting 1.8/2.5/3.0 V interfaces.
Technical Context
The R7F100GBF2DFP#BA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 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 executes up to 32 preconfigured processes-including ADC sampling, comparator comparison, and timer-triggered actions-without CPU, RAM, or flash activation.
Peripheral integration includes a logic/event link controller (ELCL) for configurable signal routing between peripherals, a 12-bit A/D converter with 26-channel input and internal 1.48 V reference, and dual D/A converters (8-bit, 0–VDD output) with real-time update capability. The device supports background data flash rewriting (BGO) and flash shield window security.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GBF2DFP#BA0?
The R7F100GBF2DFP#BA0 operates up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across the full 1.6–5.5 V supply range. At 32 MHz, minimum supply voltage is 2.7 V per datasheet timing specifications; operation below 2.7 V requires reduced clock frequencies (e.g., 24 MHz at 2.4 V, 16 MHz at 1.8 V). The R7F100GBF2DFP#BA0 maintains full peripheral functionality-including ADC, RTC, and CTSU-at all supported frequencies and voltages.
Does the R7F100GBF2DFP#BA0 support hardware debug interfaces, and what are the pin requirements?
Yes, the R7F100GBF2DFP#BA0 supports on-chip debugging via the single-wire SWD interface using dedicated TOOL0 (pin 1), TOOLRxD (P11), and TOOLTxD (P12) pins. These three pins enable full breakpoint, step-through, and memory inspection capabilities without requiring additional debug headers or JTAG adapters. The R7F100GBF2DFP#BA0 does not require external pull-ups on debug lines, as internal resistors are enabled automatically upon debug entry.
How many capacitive touch channels can the R7F100GBF2DFP#BA0 support, and what configuration options exist?
The R7F100GBF2DFP#BA0 integrates the CTSU2L unit supporting up to 32 self-capacitance keys (one pin per key) or 64 mutual-capacitance keys (8×8 matrix). It uses shared I/O pins-such as P30 (TSCAP), P20–P25, and P00–P01-with no dedicated touch-only pins. The R7F100GBF2DFP#BA0 firmware configures scan parameters (voltage, cycle count, noise rejection) per key, and supports automatic baseline tracking and drift compensation for reliable operation in varying environmental conditions.
What are the data flash endurance and write-cycle limitations for the R7F100GBF2DFP#BA0?
The R7F100GBF2DFP#BA0 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with background operation (BGO) support. Each write operation must target aligned 128-byte blocks, and erase operations are performed per 2 KB sector. The R7F100GBF2DFP#BA0 includes flash shield window protection to prevent unauthorized access to data flash contents during programming or runtime.
Can the R7F100GBF2DFP#BA0 operate reliably in industrial environments with extended temperature ranges?
Yes, the R7F100GBF2DFP#BA0 is qualified for industrial applications with an operating ambient temperature range of −40 to +105°C (3C grade), verified across voltage (1.6–5.5 V) and frequency (up to 32 MHz) specifications. It incorporates dual voltage detectors (LVD0/LVD1), enhanced ESD protection (±4 kV HBM), and robust clock fail-safe mechanisms-including automatic switch to backup oscillator on crystal failure-to ensure deterministic behavior in harsh electrical and thermal conditions. The R7F100GBF2DFP#BA0 meets AEC-Q100 stress test requirements for industrial-grade reliability.
