• Touch Sensing and Water Shield — 23-channel self-capacitive touch key support with touch-key interrupt wake-up and an integrated 4-channel mesh water shield for improved wet-environment performance.
• Analog Conversion — 12-bit A/D converter with 8 external channels and up to 150 ksps sampling for sensor and analog signal acquisition.
• Timers and PWM — Multiple timing resources including five 16-bit timers, one 8-bit timer, and four 8-bit PWM channels for motor, buzzer, backlight or LED timing control.
• I/O and High-Current Ports — Up to 26 general-purpose I/O pins with 8 high-sink current ports suitable for driving LEDs and indicators directly.
• Communications — On-chip serial interfaces including I2C, multiple USART channels and SPI support for peripheral and sensor connectivity.
• System Reliability — On-chip watchdog timer, power-on reset and selectable low-voltage reset/indicator levels to support reliable field operation.
• Power and Oscillator — Operates from 2.0 V to 5.5 V (at 16 MHz) with internal RC oscillators (HSIRC 16 MHz and LSIRC 32 kHz) and selectable system frequencies (2, 4, 8, 16 MHz).
• Package and Temperature — Available in a compact 28-pin TSSOP package and rated for operation from −40 °C to +105 °C.

Typical Applications

• Home appliance control panels — 23-channel touch sensing plus water-shielding supports responsive touch UIs for washers, ovens and kitchen appliances where moisture tolerance is required.
• Consumer touch interfaces — Integrated touch controller, ADC and high-current LED ports simplify design of user panels, status indicators and basic HMI systems.
• Smart home control devices — Compact package, serial interfaces and low-power modes enable integration into smart switches, thermostats and wall-mounted controllers.
• Industrial control panels — Wide supply range, multiple timers and robust reset/low-voltage options support reliable operation in demanding environments.

Unique Advantages

• Highly integrated touch solution: 23 self-capacitive channels and on-chip water shield reduce external components and simplify PCB routing for touch panels.
• Direct LED-driving capability: Eight high-sink current ports enable direct connection of indicator LEDs, lowering BOM and board complexity.
• Versatile analog and timing resources: 12-bit ADC (8 channels, 150 ksps) plus multiple 16-bit and 8-bit timers and PWMs provide flexibility for sensor reading and actuator control.
• Wide voltage and temperature range: 2.0–5.5 V supply operation and −40 °C to +105 °C rating support a broad set of embedded product environments.
• Compact, production-ready package: 28-pin TSSOP package offers a space-efficient footprint for consumer and appliance PCBs.
• Built-in reliability features: Watchdog timer, power-on reset and selectable low-voltage thresholds help maintain stable operation in the field.
