ATTINY13A-SSH Family Name, Microchip ATTINY13A-SSH, 8bit AVR Microcontroller, ATtiny13, 20MHz, 1 kB Flash, 8-Pin JEDEC SOIC

8-Bit PicoPower tinyAVR® Microcontrollers
Atmel's tinyAVR® devices are optimized for applications that require performance, power efficiency, and ease-of-use in a small package. All picoPower devices are designed from the ground up for lowest possible power consumption.
Small, most compact package for applications where size is criticalCapacitive TouchFast and code efficientHigh integration1.8V to 5.5V operation (0.7V operation for ATtiny43U)
Microchip Technology Microcontroller
The Microchip technology AVR family type, JEDEC SOIC package, surface mount, 8-pin picoPower tiny 8-bit microcontroller has a maximum voltage rating of 5.5V. This microcontroller operates at a maximum speed of 20MHz and features 1kb ISP flash program memory and 64bytes of internal SRAM. By executing powerful instructions in a single clock cycle, it achieves throughputs approaching 1MIPS per MHz allowing the system to optimize power consumption versus processing speed.
