The ATMEGA164PA-ANR from Microchip Technology is a high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller that combines 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 versatile microcontroller operates at a voltage range of 1.8-5.5 volts, ensuring compatibility with both commercial and industrial applications. The device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption with processing speed.

Designed for advanced control systems, the ATMEGA164PA-ANR is equipped with an array of features that enable highly sophisticated and robust embedded designs. Its In-System Programmable Flash allows the program memory to be reprogrammed in-system through an SPI serial interface or by an onboard boot program running on the AVR core. This feature provides a highly flexible and convenient way of updating applications without the need for external programming hardware.

The ATMEGA164PA-ANR is packaged in a 40-pin PDIP (Plastic Dual In-line Package), which makes it suitable for breadboarding and prototyping. It is also available in more compact TQFP and QFN/MLF packages for space-constrained applications. This microcontroller's robust set of peripherals and extensive interrupt system enable designers to create interactive, real-time systems with a high degree of control and responsiveness.

With its advanced RISC architecture, extensive memory options, and low power consumption, the ATMEGA164PA-ANR is an ideal choice for a wide range of applications, including automation, sensor systems, and IoT devices. Microchip's extensive support and resource ecosystem further ensure that development with the ATMEGA164PA-ANR is a smooth and efficient process, allowing for rapid prototyping and quick time-to-market.
