ATTINY20-MMH

The ATTINY20-MMH is a high-performance, low-power 8-bit AVR microcontroller featuring 2KB of in-system programmable Flash memory and 128 bytes of internal SRAM. With an advanced RISC architecture, it executes 112 instructions in a single clock cycle, achieving up to 12 MIPS throughput at 12MHz. The device operates over a wide voltage range of 1.8V to 5.5V, supporting speeds from 0 to 12MHz depending on supply voltage.

On-chip peripherals include a 10-bit ADC with 8 single-ended channels, two timer/counters (one 8-bit and one 16-bit with PWM outputs), an analog comparator, a programmable watchdog timer with separate oscillator, and master/slave SPI and slave TWI serial interfaces. The microcontroller supports multiple low-power modes: active mode draws 200 µA at 1MHz and 1.8V, idle mode 25 µA, and power-down mode less than 0.1 µA.

This device is available in a 20-VFQFN Exposed Pad package (20-VQFN 3x3) for surface-mount assembly, providing 12 programmable I/O lines. It is designed for industrial temperature ranges from -40°C to 85°C, making it suitable for embedded control in harsh environments.
