ATMEGA16-16AC [Microchip]

The ATmega16 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 16KB In-System Programmable Flash program memory with Read-While-Write capabilities, 512 bytes EEPROM, 1KB SRAM, 32 general purpose I/O lines, JTAG interface for boundary-scan and on-chip debugging, three flexible Timer/Counters with compare modes, an 8-channel 10-bit ADC with optional differential input and programmable gain, serial interfaces (USART, SPI, Two-wire), programmable Watchdog Timer, and six software selectable power saving modes. It supports operating voltages from 2.7V to 5.5V and speeds up to 16 MHz.
