Product details
Overview
R7F100GAG3CSP#BA0 from Renesas is a 30-pin, 96-KB code flash, 12-KB RAM RL78/G23 16-bit microcontroller operating from 1.6 to 5.5 V, featuring 41-µA/MHz active current, 210-nA data retention, capacitive touch sensing (up to 32 keys), and integrated UART, I²C, and SPI interfaces - deployed in industrial sensor nodes and low-power HMI control modules.
For engineers reviewing the R7F100GAG3CSP#BA0 datasheet, R7F100GAG3CSP#BA0 pinout, R7F100GAG3CSP#BA0 application, or R7F100GAG3CSP#BA0 equivalent, key selection criteria include its 30-pin LSSOP package, -40°C to +85°C industrial temperature grade, 96-KB flash/12-KB RAM memory configuration, ultra-low-power STOP/SNOOZE modes, and CTSU2L capacitive sensing unit for touch-button interfaces.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode) and supports multiply/divide/accumulate instructions. It integrates a SNOOZE mode sequencer (SMS) that executes up to 32 preconfigured operations without CPU wake-up, enabling autonomous low-power sensor polling.
Peripheral integration includes a 10-bit A/D converter with 8 analog inputs, 2-channel 8-bit D/A output, 2-channel comparator with selectable internal/external reference, and Logic & Event Link Controller (ELCL) for hardware-triggered peripheral chaining - all coordinated via the Data Transfer Controller (DTC) supporting block, repeat, and chain transfer modes.

FAQ
What is the maximum operating frequency and clock source flexibility for the R7F100GAG3CSP#BA0?
The R7F100GAG3CSP#BA0 supports up to 32 MHz operation using its high-speed on-chip oscillator (±1.0% accuracy), or external crystal/resonator. It also integrates selectable middle-speed (4/2/1 MHz) and low-speed (32.768 kHz) oscillators - enabling dynamic clock scaling across HALT, STOP, and SNOOZE modes without external components.
Does the R7F100GAG3CSP#BA0 support in-system programming and secure firmware updates?
Yes, the R7F100GAG3CSP#BA0 supports on-chip debugging via TOOL0 pin and self-programming with boot swapping and flash shield window protection. Its 8 KB data flash allows background rewriting (BGO) during code execution - enabling robust over-the-air updates and parameter storage without halting application logic.
How many capacitive touch channels does the R7F100GAG3CSP#BA0 support, and what configuration options exist?
The R7F100GAG3CSP#BA0 integrates the CTSU2L unit supporting self-capacitance mode for up to 32 independent touch keys - one dedicated pin per key. It does not support mutual capacitance (matrix) due to its 30-pin LSSOP package limitation, which restricts available CTSU pins to the self-capacitance subset defined in the datasheet.
What are the key power-saving modes available on the R7F100GAG3CSP#BA0, and how do they differ?
The R7F100GAG3CSP#BA0 offers HALT (CPU stopped, peripherals active), STOP (all clocks halted except RTC/LVD), and SNOOZE (peripheral sequencer active, CPU/RAM/flash powered down). STOP mode draws 210 nA with 4 KB RAM retention; SNOOZE enables autonomous ADC/timer operations at sub-µA average current - ideal for sensor polling.
Can the R7F100GAG3CSP#BA0 interface directly with 1.8-V or 2.5-V peripherals, and how is this achieved?
Yes, the R7F100GAG3CSP#BA0 supports mixed-voltage I/O: its N-ch open-drain ports tolerate 6 V, and TTL input buffers accept 1.8-V, 2.5-V, or 3.3-V logic levels. Pull-up resistors can be enabled internally - eliminating external level shifters when interfacing with lower-voltage sensors or communication ICs.
