ATTINY24A-MMH

Overview

The ATTINY24A-MMH is an 8-bit AVR microcontroller featuring a high-performance RISC architecture with 120 instructions, most executing in a single clock cycle. It integrates 2K bytes of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device includes one 8-bit and one 16-bit Timer/Counter with two PWM channels each, a 10-bit ADC with 8 single-ended channels, and a Universal Serial Interface. Operating within a supply voltage range of 1.8V to 5.5V, it supports speeds up to 20MHz at 4.5V to 5.5V. It is housed in a 20-pin Very Thin Quad Flat No Lead (VQFN) package.
