Product Overview: ATMEGA164PA-MU

The ATMEGA164PA-MU is a powerful microcontroller unit (MCU) from the well-known manufacturer Microchip Technology. This high-performance, low-power AVR® 8-bit MCU 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.

The device operates at a frequency of up to 20MHz and can be powered by a voltage range of 1.8-5.5 volts. Its robust feature set and its ability to operate under extended temperature ranges make it ideal for a broad array of applications, particularly those requiring high levels of processing power and minimal power consumption.

The ATMEGA164PA-MU is housed in a 44-pin VQFN package, which is suitable for space-constrained applications while still offering ample room for I/O connections and peripheral integration. Its compatibility with the AVR microcontroller series ensures that developers can take advantage of a wide range of existing resources, including development tools, libraries, and community support.

Key features of the ATMEGA164PA-MU include its advanced RISC architecture, which allows for high throughput with 131 powerful instructions – most of which can be executed in a single clock cycle. This leads to a remarkable performance that can reach up to 20 MIPS throughput at 20MHz. Additionally, the MCU's extensive interrupt system and its endurance for at least 10,000 write/erase cycles make it a reliable choice for long-term deployments.

For designers and engineers looking for a versatile, efficient, and reliable microcontroller for their embedded systems, the ATMEGA164PA-MU from Microchip Technology stands out as an excellent choice that balances performance, power consumption, and a wide range of features.
