Product details
Overview
R7F100GPH3CFA#BA0 from Renesas is a 100-pin, industrial-grade 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 true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA (LIN-capable), IICA, and CSI - deployed in smart home control panels requiring secure firmware updates and battery-backed human interface.
For engineers reviewing the R7F100GPH3CFA#BA0 datasheet, R7F100GPH3CFA#BA0 pinout, R7F100GPH3CFA#BA0 application, or R7F100GPH3CFA#BA0 equivalent, key selection criteria include its 100-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for ultra-low-power sensor polling, and hardware-based flash shield window for secure self-programming.
Technical Context
The R7F100GPH3CFA#BA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable 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 preconfigured processes-including ADC sampling, comparator comparison, and timer-triggered wakeups-without CPU, RAM, or flash activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-level event routing between peripherals (e.g., ADC completion triggering DMA transfer), and a Data Transfer Controller (DTC) supporting chain transfers activated by interrupt sources-reducing CPU load during burst data movement across UART, SPI, or memory buffers.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F100GPH3CFA#BA0?
The R7F100GPH3CFA#BA0 operates up to 32 MHz using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6–5.5 V supply 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 standby functions, maintaining operation down to 1.6 V.
Does the R7F100GPH3CFA#BA0 support hardware-based secure firmware updates?
Yes, the R7F100GPH3CFA#BA0 supports secure firmware updates via its flash shield window and boot swapping features. These mechanisms prevent unauthorized access to protected code regions during self-programming, and allow safe over-the-air (OTA) updates by validating new firmware in a secondary bank before atomic swap-ensuring system integrity even during power loss.
How many capacitive touch channels does the R7F100GPH3CFA#BA0 support, and what configuration options are available?
The R7F100GPH3CFA#BA0 integrates the CTSU2L capacitive sensing unit supporting up to 32 keys in self-capacitance mode (one pin per key) or 64 keys in mutual-capacitance matrix mode (8 × 8 pin grid). Both modes operate across the full 1.8–5.5 V supply range and include automatic noise cancellation for reliable operation in electrically noisy environments.
Can the R7F100GPH3CFA#BA0 perform analog-to-digital conversion while in STOP mode?
No-the R7F100GPH3CFA#BA0 cannot execute ADC conversions in STOP mode. However, it supports ADC triggering from the SNOOZE mode sequencer (SMS), which operates independently of the CPU, RAM, and flash. This allows low-power periodic sampling (e.g., every 500 ms) with sub-µA average current, making it functionally equivalent to STOP-mode sensing for most battery-powered use cases.
What serial communication protocols are natively supported by the R7F100GPH3CFA#BA0 without external transceivers?
The R7F100GPH3CFA#BA0 natively supports UARTA (with LIN-bus physical layer compliance), IICA (I²C-compatible), and CSI (SPI-compatible) interfaces. All three operate directly from GPIO pins without external level shifters or transceivers across the 1.6–5.5 V supply range. LIN compliance includes automatic sync-break detection and configurable baud rates from 1.2 to 20 kbps.
