Product Description
Microchip presents the ATMEGA88PA-AUR, a high-performance, 8-bit AVR RISC-based microcontroller designed to deliver reliable processing capabilities for advanced electronic applications. This microcontroller operates at frequencies up to 20 MHz and is equipped with an efficient RISC instruction set architecture, enabling execution of powerful instructions in a single clock cycle with throughput approaching 1 MIPS per MHz.
The ATMEGA88PA-AUR features 8kB of in-system programmable Flash memory for program storage, supported by 1kB SRAM and 512B EEPROM. It is housed in a compact 32-pin TQFP surface-mount package, making it suitable for space-constrained PCB layouts. Users benefit from 23 programmable I/O lines, 32 general purpose working registers, and three flexible timer/counters with compare modes, allowing for versatile control and timing operations.
Additionally, the device provides comprehensive serial communication options including USART, a byte-oriented 2-wire interface, and an SPI serial port. For precision measurements and analog integration, it includes an 8-channel, 10-bit ADC (applicable in TQFP/QFN/MLF packages), and one analogue comparator. Internal and external interrupts support complex real-time operations.
Operating voltage ranges from 1.8V to 5.5V, enabling compatibility with a wide variety of power systems and battery-backed designs. The microcontroller also incorporates a programmable watchdog timer with internal oscillator and offers five software-selectable power saving modes, enhancing energy efficiency in portable and embedded systems.
With robust memory, flexible I/O, and advanced control features, this device is ideal for industrial automation, laboratory instrumentation, automotive controller circuits (non-automotive standard), and commercial embedded applications. The combination of high-speed processing and reliable flash performance ensures robust data handling and responsive control.
