Product details
Overview
R7F100GPK3CFA#BA0 from Renesas is a 100-pin, industrial-grade 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 (up to 64 keys), and rich peripherals including 16-bit timers (12 channels), 12-bit ADC (26 channels), UART/LIN (6 channels), I²C (10 channels), and SPI (8 channels) - deployed in smart home control panels requiring low-power, high-integration MCU solutions.
For engineers reviewing the R7F100GPK3CFA#BA0 datasheet, R7F100GPK3CFA#BA0 pinout, R7F100GPK3CFA#BA0 application, or R7F100GPK3CFA#BA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensor polling, and CTSU2L capacitive touch unit supporting mutual capacitance matrix configurations.
Technical Context
The R7F100GPK3CFA#BA0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer executes up to 32 predefined commands-including timer triggers, ADC conversions, and CTSU scans-without CPU, RAM, or flash activation, enabling deterministic sub-microamp wake-and-measure cycles.
Peripheral integration includes an Event Link Controller (ELCL) for hardware-triggered signal routing between modules (e.g., ADC end-of-conversion → DMA transfer), a Data Transfer Controller (DTC) with chain transfer support, and dual-voltage I/O (1.8/2.5/3.0 V compatible) with configurable pull-ups and N-ch open-drain options. The device supports background data flash rewriting (BGO) with 1M-cycle endurance and on-chip debugging via SWD.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPK3CFA#BA0?
The R7F100GPK3CFA#BA0 operates up to 32 MHz using the high-speed on-chip oscillator, supported across its full 1.6–5.5 V VDD range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz for RTC and deep-sleep timing, maintaining functionality down to 1.6 V.
Does the R7F100GPK3CFA#BA0 support hardware-accelerated cryptographic operations?
No, the R7F100GPK3CFA#BA0 does not include dedicated cryptographic accelerators (e.g., AES, SHA, TRNG). It relies on software libraries for encryption tasks. For applications requiring hardware crypto, Renesas offers the RA family or RL78/G23 variants with TrustZone-enabled derivatives - but the R7F100GPK3CFA#BA0 itself provides no on-chip crypto acceleration.
How many capacitive touch channels does the R7F100GPK3CFA#BA0 support in mutual capacitance mode?
The R7F100GPK3CFA#BA0 supports up to 64 capacitive touch keys in mutual capacitance mode using an 8×8 electrode matrix configuration via its CTSU2L unit. This requires 16 dedicated I/O pins (8 X-lines, 8 Y-lines) and is validated for operation across the full industrial temperature range (-40°C to +105°C).
What debug interface does the R7F100GPK3CFA#BA0 use, and is external hardware required?
The R7F100GPK3CFA#BA0 uses the Renesas Serial Wire Debug (SWD) interface, compatible with E2 studio and CS+ IDEs. A standard SWD debug probe (e.g., E2 Lite, J-Link) is required - no on-chip debugger is integrated. Pin assignments are fixed: P10 (SWCLK), P11 (SWDIO), and P12 (RESET) serve as the primary debug interface.
Can the R7F100GPK3CFA#BA0 operate reliably at 105°C ambient temperature with full peripheral functionality?
Yes, the R7F100GPK3CFA#BA0 is rated for industrial operation from -40°C to +105°C (C-suffix, 3C grade). All specified peripherals - including CTSU2L, 12-bit ADC, UART/LIN, and SNOOZE mode sequencer - are fully functional across this range. Thermal derating is not required; however, PCB layout must ensure adequate heat dissipation for sustained 105°C operation.
