Product details
Overview
R7F100GPK2DFB#BA0 from Renesas is a 100-pin LFQFP, 0.50-mm pitch, industrial-grade (−40 to +105°C) RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, 24 KB RAM, and integrated capacitive touch sensing unit (CTSU2L). It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), supports multiple clock sources including ±1.0% accurate 32-MHz on-chip oscillator, and targets embedded control in battery-powered HMI, sensor nodes, and industrial automation.
For engineers reviewing the R7F100GPK2DFB#BA0 datasheet, R7F100GPK2DFB#BA0 pinout, R7F100GPK2DFB#BA0 application, or R7F100GPK2DFB#BA0 equivalent, key selection considerations include its 100-pin LFQFP package, 256-KB flash/24-KB RAM memory configuration, CTSU2L support for up to 64 keys in mutual-capacitance mode, SNOOZE mode sequencer for autonomous low-power sensing, and dual-voltage I/O capability (1.8–5.5 V).
Technical Context
The R7F100GPK2DFB#BA0 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 SNOOZE mode sequencer (SMS) executes up to 32 autonomous processes using 21 command types without CPU, flash, or RAM involvement-enabling periodic sensor sampling and threshold comparison at microamp-level current.
Peripheral integration includes 16-bit TAU timers (12 channels), 8-/10-/12-bit ADC (26 channels), 8-bit DAC (2 channels), 2 comparators with selectable internal/external reference, UARTA/LIN (3 channels), IICA (up to 10 channels), CSI (3–8 channels), and ELCL for event-driven peripheral linking-configured via PIOR register for flexible pin multiplexing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time control with minimal code footprint. |
| Operating Voltage | 1.6–5.5 V; supports direct interface with 1.8-V, 2.5-V, and 3.3-V peripherals without level shifters. |
| Flash/RAM | 256 KB code flash + 8 KB data flash + 24 KB RAM; sufficient for complex firmware with background data logging and OTA update buffers. |
| Power Consumption | 41 µA/MHz active current; reduces battery drain in portable devices and extends runtime in energy-harvested systems. |
| Capacitive Sensing | CTSU2L unit supporting self-capacitance (32 keys) or mutual-capacitance (8×8 matrix, 64 keys); eliminates need for external touch controller IC. |
| Package & Temp | 100-pin LFQFP (14×14 mm, 0.50-mm pitch), industrial grade (−40 to +105°C); compatible with standard reflow profiles and high-reliability environments. |
| Clock Accuracy | ±1.0% at 32 MHz (VDD = 1.8–5.5 V, TA = −20 to +85°C); enables precise timing-critical communication without external crystal. |
Pinout & Package
Package: 100-pin Low-Profile Quad Flat Package (LFQFP), 14 mm × 14 mm, 0.50-mm lead pitch, exposed pad (recommended to connect to VSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P01 | Analog input / UARTA TX/RX | Support simultaneous ADC sampling and LIN bus communication; TI00/TO00 enable timer-based pulse generation for motor control. |
