Product details
Overview
R7F100GBJ3CNP#HA0 from Renesas is a 32-pin, industrial-grade RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, UART/I²C/CSI interfaces, and supports SNOOZE mode for autonomous low-power sensor polling.
For engineers reviewing the R7F100GBJ3CNP#HA0 datasheet, R7F100GBJ3CNP#HA0 pinout, R7F100GBJ3CNP#HA0 application, or R7F100GBJ3CNP#HA0 equivalent, key selection considerations include its 32-pin HWQFN (5 × 5 mm, 0.50-mm pitch) package, -40 to +105°C industrial temperature rating, integrated CTSU2L for up to 64-key mutual-capacitance touch, and hardware-accelerated SNOOZE mode sequencer for battery-powered HMI and sensor-edge applications.
Technical Context
The R7F100GBJ3CNP#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed on-chip oscillator, ±1.0% accuracy) to 30.5 µs (32.768 kHz subsystem clock). It features a dedicated SNOOZE mode sequencer (SMS) capable of executing 32 sequential commands-including comparisons and calculations-without CPU, RAM, or flash activation, enabling deterministic low-power wake-up control.
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 a capacitive sensing unit (CTSU2L) supporting both self- and mutual-capacitance methods (up to 32 keys single-pin or 64 keys 8×8 matrix) under VDD = 1.8–5.5 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response and compact code size for resource-constrained embedded control. |
| Flash Memory | 256 KB code flash + 8 KB data flash; supports background operation (BGO) and 1M rewrite cycles for robust firmware updates and parameter storage. |
| RAM | 24 KB on-chip RAM; retains data at 210 nA in STOP mode, enabling long-term state preservation in battery-backed systems. |
| Operating Voltage | 1.6–5.5 V single supply; eliminates need for external voltage regulators in multi-rail or battery-powered designs. |
