• Memory Combined internal RAM architecture with 256 bytes IRAM and 2,304 bytes XRAM (total ≈2.5 Kbytes) for stack, variables and data buffering.
• Analog 12-bit A/D converter with up to 15 input channels and sampling performance listed at 133 ksps for accurate sensor acquisition.
• Timers & PWM Multiple timers including one Basic Interval Timer, one Watchdog Timer, one 8-bit timer (T0) and five 16-bit timers (T1–T5) for timing, pulse generation and PWM; dedicated 8-bit PWM and buzzer output available.
• Communications Multiple serial peripherals including USI0/1 (configurable as USART/SPI/I2C) and additional USART channels for flexible host and peripheral connectivity.
• GPIO & High-Current Port Up to 42 general-purpose I/O ports in the 44-LQFP package with eight high-sink-current P3 pins for direct LED or load driving and support for LCD segment control (24 segments × 8 commons).
• Oscillator & Clock Internal and external clock support including internal RC sources and crystal options (main and sub clocks) to match application frequency and accuracy needs.
• Power Management & Safety Wide operating voltage range and multiple reset/voltage-monitor functions: Power-On Reset (POR), multi-level Low-Voltage Reset (LVR) and Low-Voltage Indicator (LVI). Stop and Idle low-power modes plus a configurable Watch Timer for periodic wake-up.
• Package & Environmental Range 44-LQFP (10 × 10 mm, 0.8 mm pitch) surface-mount package and operating temperature options covering –40 °C to +105 °C depending on device selection.

Typical Applications

• Home appliance control — Reliable control for user interfaces, timing and motor or actuator sequencing using the integrated timers, PWM and LCD/LED drivers.
• Sensor hub and data acquisition — Multi-channel 12-bit ADC and ample I/O make the device suitable for aggregating and preprocessing sensor signals.
• Embedded human-machine interfaces — On-chip LCD driver, high-current LED port and serial interfaces enable compact UI and status indication designs.
• General embedded control — Timers, watchdog, nonvolatile memory and flexible serial peripherals support a wide range of control and communication tasks in industrial and consumer devices.

Unique Advantages

• Integrated, production-ready memory — 64 KB Flash with ISP and 2 KB EEPROM with high endurance simplify firmware updates and long-term data storage without external memory.
• Comprehensive peripheral set — Multiple 16-bit and 8-bit timers, programmable pulse generation and multi-protocol serial interfaces reduce external components and PCB complexity.
• Precision analog input — 12-bit ADC with up to 15 channels provides high-resolution measurement capability for multi-sensor designs.
• Flexible power and reset control — Wide supply voltage range (1.8–5.5 V) plus POR, multi-level LVR and LVI support robust operation across battery and line-powered systems.
• On-board display and drive support — Built-in LCD driver and dedicated high-sink I/O ease implementation of user interfaces and visual indicators.
• Field update and reliability — In-system programming for Flash and proven memory endurance figures help reduce field service and enable firmware upgrades.
