ATMEGA88PA-MMN

Overview

The ATMEGA88PA-MMN is an 8-bit AVR microcontroller featuring 8 kB of Flash memory, 512 B of EEPROM, and 1 kB of SRAM. It operates with a maximum clock frequency of 20 MHz and supports a supply voltage range of 1.8 V to 5.5 V. The device includes an 8-channel 10-bit ADC, 23 I/O lines, and interfaces such as SPI, USART, and I2C. It is housed in a 28-VQFN package and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrated low-power 8-bit AVR architecture for efficient processing
• Built-in analog-to-digital conversion with multiple channels
• Supports standard serial communication protocols including SPI and USART

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control modules operating in extended temperature environments
• Sensor interface circuits utilizing the internal ADC capabilities

Procurement Notes

Verify the specific suffix MMN corresponds to the 28-VQFN package and industrial temperature grade (+105°C) rather than commercial grades. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure ESD handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this component when an 8-bit AVR core is required with extended temperature tolerance up to 105°C. The 28-VQFN package suits space-constrained surface-mount designs. Verify that the 20 MHz speed and 8 kB program memory meet application requirements compared to other ATmega88 variants.

Part Context

This part belongs to the ATmega88PA family, which offers enhanced power efficiency compared to standard ATmega88 models. The MMN suffix specifically denotes the 28-lead Very Thin Quad Flat No-lead (VQFN) package configuration suitable for compact PCB layouts.

Replacement Considerations

ATMEGA88PA-MMHR provides similar specifications but may differ in packaging or temperature rating verification.
