• Analog and Data Conversion  12-bit A/D converter with 16 channels for multi-sensor acquisition and analog monitoring.
• Timers and PWM  Multiple timing resources including ten 16-bit timers, one 32-bit timer and 16-bit PWM for precision timing, control loops and motor or actuator drive.
• LED and High-Current Ports  Integrated LED driver / high-current port support for up to 16 channels of direct LED or indicator control.
• Connectivity  On-chip UART, SPI and I2C interfaces to connect displays, sensors, external memories and communication peripherals.
• System and Reliability  Watchdog timer and support for external and internal oscillators to improve system robustness and flexible clock sources.
• Power and Temperature  Operates from 3 to 5.5 V and rated for −40 to 85 °C ambient, enabling wide supply and environmental tolerance.
• Package and I/O  100-MQFP package (14 × 20 × 0.6 mm) with up to 90 I/O pins for dense integration in appliance and consumer designs.

Typical Applications

• Home Appliances  Main controller functions for washing machines, ovens and refrigeration systems leveraging integrated timers, PWM and ADC channels.
• Consumer Electronics  System control and user interface management for devices requiring display/LED control, connectivity and non-volatile data storage.
• Sensor Acquisition and Control  Multi-channel 12-bit ADC and timers for environmental sensing, temperature monitoring and control loops.
• LED and Indicator Systems  Direct LED driver support for status indicators, backlighting and segmented displays with centralized control.

Unique Advantages

• High on-chip storage: 384 Kbytes Flash plus 32 Kbytes data flash and 24 Kbytes SRAM reduce external memory requirements and simplify BOM.
• Comprehensive analog and timing peripherals: 12-bit/16-channel ADC, multiple 16-bit timers, a 32-bit timer and 16-bit PWM provide the building blocks for precise sensing and control.
• Rich connectivity: I2C, SPI and UART interfaces enable flexible integration with sensors, displays and communication modules.
• Wide supply and temperature range: 3–5.5 V operation and −40 to 85 °C rating support a variety of consumer and appliance environments.
• High I/O density in a compact package: Up to 90 I/O pins in a 100-MQFP package allow integration of many peripherals and external devices without larger packages.
• Robust system functions: External/internal oscillator options and a watchdog timer support reliable operation and design flexibility.
