It integrates capacitive touch sensing (up to 32 keys), 12-bit ADC (26 channels), dual DAC, RTC, and ultra-low-power STOP mode (210 nA data retention).
For engineers reviewing the R7F100GAH3CSP#BA0 datasheet, R7F100GAH3CSP#BA0 pinout, R7F100GAH3CSP#BA0 application, or R7F100GAH3CSP#BA0 equivalent, key selection criteria include its 30-pin LSSOP package, 128 KB flash/16 KB RAM memory configuration, industrial-grade temperature rating, and integrated CTSU2L capacitive sensing unit for human interface design.
Technical Context
The R7F100GAH3CSP#BA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer enables autonomous low-power sensor polling without CPU wake-up, using 32 programmable commands across 21 operations.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer support, and multiple serial interfaces: up to 10 I²C/Simplified I²C channels, 6 UARTA/LIN channels, and 8 CSI/SPI channels - all mapped to its 30-pin LSSOP I/O set.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GAH3CSP#BA0?
The R7F100GAH3CSP#BA0 supports a maximum system clock of 32 MHz using the high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.03125 µs. This timing is achievable with the high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and -40 to +85°C ambient conditions - verified in the R01DS0395EJ0140 datasheet Section 1.1.
Does the R7F100GAH3CSP#BA0 support LIN bus communication, and which peripheral implements it?
Yes, the R7F100GAH3CSP#BA0 supports LIN 2.2 bus communication via its UARTA peripheral. UARTA provides hardware-level LIN frame formatting, checksum generation, and baud rate synchronization compliant with ISO 17987-4. This capability is confirmed in Section 1.1 "Serial interface" of the R01DS0395EJ0140 datasheet and applies specifically to the RL78/G23 family including the R7F100GAH3CSP#BA0.
How many capacitive touch channels does the R7F100GAH3CSP#BA0 support, and what configuration options are available?
The R7F100GAH3CSP#BA0 supports up to 32 capacitive touch keys using its CTSU2L unit in self-capacitance mode (one pin per key), or up to 64 keys in mutual-capacitance matrix mode (8 × 8). Both configurations operate within VDD = 1.8–5.5 V and are explicitly documented for the RL78/G23 family in Section 1.1 "Capacitive sensing unit" of R01DS0395EJ0140 - applicable to R7F100GAH3CSP#BA0 as a member of the G-series memory variant.
What is the data flash endurance specification for the R7F100GAH3CSP#BA0, and is background operation supported?
The R7F100GAH3CSP#BA0 features 8 KB of data flash rated for 1,000,000 rewrite cycles (typical) and supports Background Operation (BGO). During BGO, the CPU can execute instructions from program memory while simultaneously rewriting data flash - enabling seamless firmware parameter updates without halting real-time tasks. This is specified in Section 1.1 "Data flash memory" of R01DS0395EJ0140 and confirmed for all RL78/G23 variants including R7F100GAH3CSP#BA0.
Which debug interface does the R7F100GAH3CSP#BA0 use, and what pins are required for programming?
The R7F100GAH3CSP#BA0 uses the on-chip debug interface accessible via the TOOL0 pin (P40) and RESET pin. Programming and debugging require connection to these two pins plus VDD and VSS - no dedicated SWD or JTAG pins are used. This single-wire debug architecture is defined in Section 1.3.1 "30-pin products" and Table 1-2 of R01DS0395EJ0140, confirming P40/TOOL0 as the sole debug I/O for the R7F100GAH3CSP#BA0 in LSSOP package.
