ATMEGA88PA-MN

Overview

The ATMEGA88PA-MN is an 8-bit AVR microcontroller featuring a 32-VQFN (5x5) package. It integrates 8KB of in-system programmable Flash, 1KB SRAM, and 512B EEPROM. The device operates at frequencies up to 20MHz with a supply voltage range of 1.8V to 5.5V. Key peripherals include eight 10-bit ADC channels, three timers/counters, and communication interfaces such as SPI, USART, and I2C. It supports multiple sleep modes and includes hardware features like a watchdog timer and power-on reset.

Feature Summary

• High-performance 8-bit AVR architecture with RISC instruction set
• Integrated non-volatile memory for program storage and data retention
• Multiple analog-to-digital conversion channels for sensor interfacing
• Comprehensive peripheral set including timers and serial communication modules

Applications

• Embedded control systems requiring low power consumption
• Industrial automation devices with sensor input requirements
• Consumer electronics utilizing compact surface-mount packaging
• Battery-powered applications benefiting from extended sleep modes

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the 32-VQFN configuration. Cross-reference datasheet revisions to validate pinout consistency and electrical characteristics prior to integration into new designs.

Selection Notes

Select this component when a balance of processing speed and memory capacity is required within a small form factor. The 20MHz operation provides sufficient throughput for general-purpose control tasks. Consider the 1.8V minimum supply voltage for battery-operated designs. Evaluate the 32-pin count against available I/O requirements before finalizing the selection.

Part Context

This part belongs to the ATmega88PA family, which offers enhanced low-power performance compared to standard variants. The series is designed for cost-sensitive applications needing reliable 8-bit processing. The PA designation typically indicates optimized power consumption characteristics while maintaining functional compatibility with other members of the ATmega88 family.

Replacement Considerations

ATMEGA88PA-MMNR: Offers identical core specifications but utilizes a 28-VQFN package instead of the 32-VQFN. Verify footprint compatibility if substituting directly on a printed circuit board.
