The ATMEGA649A is an 8-bit microcontroller from Microchip Technology, Inc., featuring a high-performance, low-power AVR RISC architecture. It supports up to 16 MIPS throughput at 16 MHz and includes 64 KB of in-system programmable Flash memory, 2 KB of EEPROM, and 4 KB of SRAM. The device is equipped with 54 general-purpose I/O lines and offers a variety of peripheral features, including multiple timer/counters, an 8-channel 10-bit ADC, and a programmable serial USART. It also includes a JTAG interface for debugging and programming, as well as a complete on-chip LCD controller. The ATMEGA649A operates within a voltage range of 1.8 to 5.5 volts and supports five power-saving modes, making it suitable for applications requiring efficient power management. The device is rated for an industrial temperature range of -40¬8C to 85¬8C.
The high-performance, low-power Microchip 8-bit AVR® RISC-based microcontroller combines 64 KB ISP Flash memory with read-while-write capabilities, 2 KB EEPROM, 4 KB SRAM, 54/69 general purpose I/O lines, 32 general purpose working registers, a JTAG interface for boundary-scan and on-chip debugging/programmin
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
