ATTINY20-SSU

The ATTINY20-SSU is a low-power, high-performance 8-bit AVR microcontroller from Microchip Technology. It is built around an advanced RISC architecture with 112 instructions, most executed in a single clock cycle. The device features 2KB of in-system programmable Flash memory and 128 bytes of internal SRAM, with a maximum clock frequency of 12MHz, delivering up to 12 MIPS throughput.

This microcontroller includes a rich set of peripherals: an 8-bit timer/counter with two PWM channels, a 16-bit timer/counter with two PWM channels, a 10-bit ADC with 8 single-ended channels, an analog comparator, and a programmable watchdog timer. Communication interfaces include master/slave SPI and slave TWI (I2C). The device supports 12 programmable I/O lines in the 14-pin SOIC package.

Operating from 1.8V to 5.5V, the ATTINY20-SSU is optimized for low-power applications. Typical active mode current is 200 µA at 1MHz and 1.8V, idle mode is 25 µA, and power-down mode draws less than 0.1 µA. The industrial temperature range of -40°C to 85°C makes it suitable for demanding environments.

The part is supplied in a 14-SOIC (0.154", 3.90mm width) surface-mount package with tube packaging. It is RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited). Suitable for applications requiring compact size, low power, and basic connectivity.
