• Clock and Timing  Internal 16 MHz RC oscillator (±2.0%, TA = 0 ~ +50 °C) plus support for external clock sources; dedicated watchdog timer with RC oscillator (5 kHz).
• Timers and PWM  Multiple timing resources including six 16-bit timers, four 8-bit timers, six 16-bit PWM channels and four 8-bit PWM channels for pulse generation and timing control.
• Analog  12-bit A/D converter with up to 15 input channels and 50 ksps sampling rate for accurate sensor interfacing.
• Interfaces  Rich serial connectivity with up to three UART channels, two SPI channels and two USI sets supporting UART/SPI/I²C-like functions.
• Peripherals and System  Built-in 16-bit CRC/checksum generator, buzzer driver, power-on reset, low-voltage detect/reset and on-chip LDO regulator.
• I/O and Package  Up to 61 programmable I/O lines in a compact 64‑QFN surface-mount package (also available in LQFP variants).
• Power and Environmental  Wide supply range 2.2 V to 5.5 V and industrial temperature rating from −40 °C to 85 °C for broad operating conditions.

Typical Applications

• Home Appliances  Implement control and sensing functions using integrated ADC, timers and PWM channels for consumer devices.
• Industrial Control  Support machine control and monitoring tasks with extensive I/O, robust reset/voltage detection and CRC checksum generation.
• Embedded Control Systems  Provide a compact, programmable core with on-chip Flash and a wide peripheral set for general embedded applications.

Unique Advantages

• Highly integrated peripheral set: Combines ADC, multiple timers, PWM channels, UART/SPI/USI and CRC on-chip to reduce BOM and simplify board design.
• Flexible memory architecture: 64 Kbytes Flash plus separate IRAM and XRAM regions give predictable program/data placement for firmware and buffers.
• Wide supply and temperature range: 2.2–5.5 V operation and −40 °C to 85 °C rating support diverse system power and environmental requirements.
• On-chip programming and debug support: In-system programming and on-chip debug facilities streamline development and production programming.
• Compact, high-pin-count package: 64-QFN provides up to 61 programmable I/O lines in a small surface-mount footprint for space-constrained designs.
