Product details
Overview
R7F100GBJ2DNP#AA0 from Renesas is a 32-pin 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 true low-power operation (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit timers, 12-bit ADC, and UART/I²C/SPI interfaces - deployed in battery-powered consumer HMI and sensor edge nodes.
For engineers reviewing the R7F100GBJ2DNP#AA0 datasheet, R7F100GBJ2DNP#AA0 pinout, R7F100GBJ2DNP#AA0 application, or R7F100GBJ2DNP#AA0 equivalent, key selection criteria include its HWQFN-32 package, -40°C to +85°C industrial-grade temperature range, SNOOZE mode sequencer for ultra-low-power wake-up control, and integrated CTSU2L supporting up to 64-key mutual-capacitance touch panels.
Technical Context
The R7F100GBJ2DNP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes, with hardware-based SNOOZE mode sequencer (SMS) enabling 32-step autonomous low-power processing without CPU or memory activation.
Peripheral integration includes a 12-bit A/D converter with 26-channel analog input, dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and Logic & Event Link Controller (ELCL) for configurable event-driven peripheral chaining - all mapped to its 32-pin HWQFN footprint with dedicated CTSU2L pins (P30/TSCAP, P31/TS01, P70/TS02, etc.) and controlled-current drive ports.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GBJ2DNP#AA0?
The R7F100GBJ2DNP#AA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator. At this speed, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz (subsystem clock), yielding a 30.5 µs instruction cycle - enabling precise real-time control while minimizing power consumption in sleep-aware applications.
Does the R7F100GBJ2DNP#AA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GBJ2DNP#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) supporting both self-capacitance (up to 32 independent keys) and mutual-capacitance (8×8 matrix = 64 keys). It includes built-in noise cancellation, auto-calibration, and dedicated pins (e.g., P30/TSCAP, P31/TS01, P70/TS02) - all operable within the full -40°C to +85°C temperature range without external components.
How does the SNOOZE mode sequencer (SMS) in the R7F100GBJ2DNP#AA0 reduce system-level power consumption?
The SNOOZE mode sequencer (SMS) in the R7F100GBJ2DNP#AA0 executes up to 32 predefined operations - such as ADC sampling, value comparison, or GPIO toggling - autonomously without waking the CPU, flash, or RAM. This enables ultra-low-power periodic sensing (e.g., every 500 ms) at currents below 1 µA, making the R7F100GBJ2DNP#AA0 ideal for battery-operated devices requiring multi-year operation on a single coin cell.
What are the key differences between the R7F100GBJ2DNP#AA0 and the R7F100GBJ3CNP#AA0 variants?
The R7F100GBJ2DNP#AA0 and R7F100GBJ3CNP#AA0 share identical silicon, pinout, and feature set. The sole differences are ambient temperature rating (R7F100GBJ2DNP#AA0: -40°C to +85°C; R7F100GBJ3CNP#AA0: -40°C to +105°C) and packaging specification (DNP = consumer tray; CNP = industrial tray). No firmware or hardware changes are needed when migrating between them.
Can the R7F100GBJ2DNP#AA0 perform background data flash writes while executing code from main flash memory?
Yes, the R7F100GBJ2DNP#AA0 supports Background Operation (BGO) for data flash. Code execution continues uninterrupted from the main code flash memory while data flash is being rewritten - essential for robust firmware updates, parameter logging, or secure key storage in field-deployed devices without service interruption.
