ATMEGA88PA-AUR

Microcontrollers Overview

The ATMEGA88PA-AUR is an 8-bit AVR microcontroller manufactured by Microchip Technology, housed in a 32-TQFP package. It features 8KB of programmable Flash memory, 512 bytes of EEPROM, and 1KB of SRAM. The device operates at a maximum clock frequency of 20MHz with a supply voltage range of 1.8V to 5.5V. It includes 23 general-purpose I/O lines, an 8-channel 10-bit ADC, and communication interfaces such as SPI, I2C, and USART. The component supports industrial temperatures from -40°C to +85°C and utilizes surface-mount installation.

Microcontrollers Procurement Notes

Verify the specific suffix 'AUR' indicates the reel or cut tape packaging variant distinct from the tray-packaged 'AU' version. Confirm that the ordering information matches the required quantity increments for reel-based distribution. Ensure compatibility with existing PCB footprints designed for the 32-TQFP form factor before finalizing procurement decisions.

Microcontrollers Selection Notes

Select this model when 8KB of program memory and 1KB of RAM are sufficient for the application logic. Consider the 20MHz processing speed and 1.8V-5.5V operating range for power-constrained environments. Evaluate the need for the specific 32-TQFP surface-mount package and industrial temperature rating compared to other available pinouts or memory sizes within the ATmega family.

Microcontrollers Part Context

This component belongs to the ATmega88PA series, which is part of the broader AVR 8-bit microcontroller portfolio. It shares architectural similarities with the ATmega48PA and ATmega168PA, differing primarily in memory capacities. The 'PA' designation typically denotes enhanced low-power characteristics within the standard ATmega88 line.

Microcontrollers Replacement Considerations

ATMEGA88PA-AU serves as a direct functional substitute if tray packaging is acceptable instead of reel packaging. ATMEGA88PB-AUR may be considered if higher performance or additional features are required, provided pin compatibility is verified.
