Microchip Technology ATMEGA164A-AU

The ATMEGA164A-AU is a high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller from Microchip Technology, combining 16KB ISP flash memory, 1KB EEPROM, 2KB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, a real-time counter, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a six-channel 10-bit A/D converter (eight channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes.

This powerful microcontroller is designed to deliver the versatility and efficiency required by modern embedded systems. With its robust instruction set and multiple power-saving modes, the ATMEGA164A-AU is optimized for applications that require complex real-time control, such as industrial control systems, sensor networks, and automotive electronics.

The device supports a throughput of 20 MIPS at 20 MHz and operates between 1.8-5.5 volts. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
