Product details
Overview
R7F100GPN3CFB#AA0 from Renesas is a 100-pin LFQFP, industrial-grade RL78/G23 16-bit MCU with 192 KB code flash, 8 KB data flash, and 20 KB RAM, operating from 1.6–5.5 V. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UARTA (6 channels), IICA (10 channels), and CSI (8 channels), targeting low-power HMI and sensor-edge control applications.
For engineers reviewing the R7F100GPN3CFB#AA0 datasheet, R7F100GPN3CFB#AA0 pinout, R7F100GPN3CFB#AA0 application, or R7F100GPN3CFB#AA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40 to +105°C industrial temperature rating, 192 KB/8 KB/20 KB memory configuration, CTSU2L support for up to 64 keys in mutual-capacitance mode, and SNOOZE mode sequencer enabling CPU-free periodic sensing.
Technical Context
The R7F100GPN3CFB#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its power management includes HALT, STOP, and SNOOZE modes - the latter using a dedicated sequencer with 32 programmable steps and 21 command types to perform autonomous analog sensing and comparison without CPU wake-up.
Peripheral integration includes a Logic & Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a Remote Control Signal Receiver with 4-pattern waveform matching. The CTSU2L unit operates across VDD = 1.8–5.5 V and supports both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) configurations.

Pinout & Package
Package: 100-pin LFQFP, 14 × 14 mm, 0.50-mm pitch, industrial-grade (−40 to +105°C), tray packaging (#AA0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P01 | ADC input / UARTA TX/RX | Support simultaneous analog sensing and serial communication; TI00/TO00 on P00 enables PWM-driven LED dimming synchronized with touch detection. |
| P10–P17 | SAU/SPI/I²C/UARTA pins | Configurable serial array unit channels allow concurrent UARTA (LIN-compliant), IICA (10-channel), and CSI (8-channel) operation without resource conflict. |

FAQ
What is the maximum operating temperature specification for the R7F100GPN3CFB#AA0?
The R7F100GPN3CFB#AA0 is rated for industrial operation from −40°C to +105°C ambient temperature. This specification is confirmed in the RL78/G23 datasheet (R01DS0395EJ0140 Rev.1.40, Section 1.1), where "3C" in the part number denotes industrial temperature grade. The device maintains full functionality and timing compliance across this range when properly heatsinked and within recommended power dissipation limits.
Does the R7F100GPN3CFB#AA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GPN3CFB#AA0 integrates the CTSU2L capacitive sensing unit. It supports up to 32 keys in self-capacitance mode (one pin per key) or up to 64 keys in mutual-capacitance matrix mode (8 rows × 8 columns), as specified in Section 1.1 of the RL78/G23 datasheet. The unit operates across VDD = 1.8–5.5 V and includes built-in noise cancellation and auto-calibration features.
What memory configuration does the R7F100GPN3CFB#AA0 have, and is data flash available for parameter storage?
The R7F100GPN3CFB#AA0 has 192 KB of code flash memory, 8 KB of data flash memory, and 20 KB of RAM. Data flash supports background operation (BGO), enabling code execution from program memory while rewriting data flash - ideal for storing calibration values, device settings, or logged events without interrupting real-time tasks.
Which serial communication interfaces are available on the R7F100GPN3CFB#AA0, and how many channels does each support?
The R7F100GPN3CFB#AA0 provides UARTA (6 channels), IICA (10 channels), and CSI (8 channels), as documented in Section 1.1 of the RL78/G23 datasheet. UARTA supports LIN-bus protocol; IICA includes clock stretching and 10-bit addressing; CSI functions as a simplified SPI with configurable frame format and slave select control.
What power-saving modes are implemented in the R7F100GPN3CFB#AA0, and what is the lowest current consumption achievable?
The R7F100GPN3CFB#AA0 supports HALT (41 µA/MHz), STOP (210 nA with 4 KB RAM retention), and SNOOZE modes. In STOP mode with full RAM retention, current drops to 210 nA - verified in the RL78/G23 datasheet (R01DS0395EJ0140 Rev.1.40, Section 1.1). SNOOZE mode enables autonomous peripheral operation (e.g., CTSU2L scanning) without CPU wake-up, further reducing average system current.
