ATMEGA88PA-MNR

Overview

The ATMEGA88PA-MNR is an 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash memory, 1KB of SRAM, and 512 bytes of EEPROM. It operates at a maximum clock frequency of 20MHz with a supply voltage range of 1.8V to 5.5V. The device includes eight 10-bit ADC channels, three timers/counters, and interfaces such as SPI, I2C, and USART. It is housed in a 32-VQFN (5x5) package and supports an operating temperature range from -40°C to 105°C.

Feature Summary

• Integrates high-density non-volatile memory including 8KB Flash, 1KB SRAM, and 512B EEPROM for robust data retention and program storage.
• Features an advanced RISC core delivering 20 MIPS throughput at 20MHz with single-cycle instruction execution.
• Includes multiple peripheral modules such as six-channel PWM, two 8-bit timers, one 16-bit timer, and an on-chip analog comparator.

Applications

• Embedded control systems requiring low power consumption
• Industrial automation devices
• Smart home appliances

Procurement Notes

Verify the specific suffix 'MNR' against the manufacturer's official datasheet to confirm the 32-VQFN package and tape-and-reel packaging configuration. Ensure the component meets the required industrial temperature range specifications for your application environment before procurement.

Selection Notes

Select this model when a compact 32-pin QFN footprint is required alongside standard AVR functionality. It serves as a suitable alternative to other ATmega88 variants if the specific MNR package style or extended temperature rating is necessary for the design constraints.

Part Context

This component belongs to the Microchip AVR ATmega family, known for combining high performance with low power consumption. The ATmega88PA series specifically offers enhanced energy efficiency compared to standard versions, making it ideal for battery-operated applications within the broader embedded controller market.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives like ATMEGA88PA-MU or ATMEGA88PA-MMNR, ensuring package dimensions and thermal characteristics match the existing PCB layout.
