• Program and Data Memory  64 KB of on-chip code Flash memory (10,000 write endurance) and 4 KB of SRAM for application and runtime data.
• Analog  12-bit A/D converter with 16 external input channels plus one internal reference channel for precise sensor measurements.
• Touch and Proximity  32-channel self-capacitive touch sensing and 4-pair capacitive force sensing with touch-key interrupt wake-up and 10 V conducted susceptibility immunity; includes water-shield support for enhanced reliability.
• Timers and PWMs  Multiple timers including Basic Interval Timer, Watchdog Timer, one 8-bit timer and multiple 16-bit timers for event counting, timing and PWM-related tasks.
• Interfaces  Serial connectivity including I2C (×1), SPI (×3) and USART (×3) for sensors, peripherals and host communication.
• System Reliability  On-chip Power-On Reset (POR), Low-Voltage Reset (LVR) with selectable release levels and a Low-Voltage Indicator with multiple thresholds to help ensure predictable behavior under brownout conditions.
• Oscillators & Low Power  Built-in RC oscillators (HSIRC 16 MHz and LSIRC 32 kHz), a 32 kHz watchdog oscillator, and STOP/IDLE power-down modes to support energy-efficient operation.
• I/O and Drive  Up to 46 general-purpose I/O pins with 8 high-sink current ports for direct drive of common loads.
• Supply and Temperature  Wide operating supply range and reset thresholds: nominal 2.0 V–5.5 V operation (16 MHz) with additional operating mode thresholds for touch and precision oscillator modes; specified operating temperature range -40 °C to +105 °C.
• Package and Mounting  Available in a 48-LQFP surface-mount package (7 × 7 mm, 0.5 mm pitch) for compact board designs.

Typical Applications

• Home Appliances  Capacitive touch panels, control knobs and user interfaces where integrated touch sensing and key wake-up reduce system BOM and simplify enclosure design.
• Consumer Electronics  Touch-enabled remotes, handheld controls and compact devices requiring low-power operation, serial connectivity and onboard ADC for sensors.
• Smart Home & IoT Devices  Sensor interfacing and HMI control with integrated ADC channels, multiple serial ports and watchdog/POR features for reliable unattended operation.
• Industrial Control Panels  Interface controllers that benefit from a wide supply voltage window, robust reset options and extended temperature range for reliable field operation.

Unique Advantages

• Highly integrated feature set: 64 KB Flash, 4 KB SRAM, 12-bit ADC and 32-channel touch sensing on a single chip reduce external components and simplify system design.
• Purpose-built touch support: Self-capacitive and force-sensing channels with touch-key interrupt wake-up and conducted-susceptibility immunity enhance performance of touch UIs in real environments.
• Flexible serial connectivity: Multiple SPI and USART channels plus I2C enable concurrent connections to sensors, displays and communication modules without external multiplexing.
• Robust reset and voltage management: On-chip POR, selectable LVR levels and a low-voltage indicator help maintain predictable behavior during supply transients and brownout events.
• Compact package, ready for production: 48-LQFP (7 × 7 mm) surface-mount package supports high-density PCB layouts while providing ample I/O for interface-rich applications.
• Energy-conscious operation: Internal oscillators and STOP/IDLE modes support low-power designs while retaining touch and wake-up capability.
