• Power and Reset Power-On Reset (POR) and Low-Voltage Reset (LVR) with configurable release and indicator levels; operating voltage from 2.0 V to 5.5 V (2.0 V–5.5 V @ 16 MHz, and 2.7 V–5.5 V for higher oscillator accuracy modes).
• Oscillators & Clocking On-chip HSIRC 16 MHz (±1.5% @ 0–60°C; ±2.5% @ -40–85°C) and LSIRC 32 kHz, selectable system operating frequencies of 2, 4, 8 and 16 MHz, plus a 32 kHz WDT oscillator.
• Analog 12-bit A/D converter with 16 external input channels plus one internal reference channel for multi-sensor acquisition.
• Touch & Sensing 32-channel self-capacitive touch sensing and 4-pair capacitive force sensing, with 10 V conducted susceptibility immunity and touch-key interrupt wake-up; includes 4-channel water-shield mesh support.
• Timers & Safety Basic Interval Timer (BIT), Watchdog Timer (WDT), one 8-bit timer and five 16-bit timers for precise timing, PWM and safety watchdog functions.
• Interfaces Multiple serial interfaces: I2C ×1, SPI ×3 and USART ×3 for display, sensor and peripheral connectivity.
• GPIO & Package Up to 46 general-purpose I/O pins (including 8 high-sink ports); available in a 48‑LQFP package (7 × 7 mm, 0.5 mm pitch) suitable for surface-mount assembly.
• Environmental Range Industrial operating temperature from -40°C to +85°C and support for STOP/IDLE low-power modes.

Typical Applications

• Touch user interfaces — Capacitive keypads, control panels and touch controls using the 32-channel self-capacitive sensor and interrupt wake-up features.
• Smart proximity sensing — Proximity detection and presence sensing leveraging on-chip touch and sensing capabilities.
• Sensor integration and acquisition — Multi-channel 12-bit ADC and serial interfaces for collecting and processing analog sensor data.
• Embedded control panels — Time-critical control, PWM and watchdog supervision for appliance and equipment control tasks.

Unique Advantages

• Highly integrated sensing and control: On-chip capacitive touch (32 channels), capacitive force sensing and a 12-bit, 16-channel ADC reduce external components and simplify PCB design.
• Flexible serial connectivity: I2C, multiple SPI and USART channels allow easy interfacing to displays, external sensors and communication modules.
• Robust power and reset management: POR, multi-level LVR and low-voltage indicator options provide predictable behavior across the 2.0–5.5 V input range.
• Reliable on-chip clock sources: HSIRC and LSIRC with specified tolerances across temperature support stable timing without external crystals for many designs.
• Design-ready I/O count and package: 46 GPIOs and a 48‑LQFP 7×7 mm package provide ample pinout for complex HMI and sensor layouts while remaining suitable for surface-mount production.
