ATMEGA88PA-MU

The ATMEGA88PA-MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features an advanced RISC architecture with 131 instructions, most executed in a single clock cycle. The device offers 8KB of in-system self-programmable Flash memory, 1KB of SRAM, and 512 bytes of EEPROM, providing ample storage for embedded applications.

Key electrical specifications include a wide operating voltage range of 1.8V to 5.5V and a maximum clock frequency of 20 MHz, delivering up to 20 MIPS throughput. The microcontroller integrates 23 programmable I/O lines, an 8-channel 10-bit ADC, and multiple serial communication interfaces including I²C, SPI, and USART. On-chip peripherals include two 8-bit timers, one 16-bit timer, six PWM channels, brown-out detection, power-on reset, and a watchdog timer.

The device is designed for industrial temperature ranges from -40°C to 85°C and is available in a compact 32-VFQFN exposed pad package (32-VQFN, 5x5mm) for surface mount assembly. Typical active current consumption is 0.2 mA at 1 MHz and 1.8V, with power-down current as low as 0.1 µA, making it suitable for battery-powered applications.

This microcontroller is ideal for a wide range of embedded control applications including industrial automation, consumer electronics, and sensor interfaces.
