ATMEGA88PA-MUR

Overview

The ATMEGA88PA-MUR is an 8-bit AVR microcontroller featuring 8 kB of in-system programmable Flash, 512 B EEPROM, and 1 kB SRAM. It operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. The device utilizes a VQFN-32 package and provides 23 I/O lines. It includes an 8-channel 10-bit ADC, hardware multiplier, and supports internal oscillators. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Advanced RISC architecture delivering up to 20 MIPS throughput at 20 MHz
• Non-volatile memory segments with true read-while-write capability
• Integrated capacitive touch sensing support via QTouch library
• Peripheral set including dual 8-bit timers, one 16-bit timer, and multiple communication interfaces

Applications

• Embedded control systems requiring low power consumption
• Industrial equipment utilizing capacitive touch interfaces
• Consumer electronics operating within extended temperature ranges

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through current datasheets. Check for product discontinuance notifications or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when 8 kB program memory and 23 general-purpose I/Os are required in a compact VQFN-32 form factor. Ensure the design accommodates the 1.8 V to 5.5 V supply range and 20 MHz processing speed. Verify that the thermal characteristics of the VQFN package meet the application's heat dissipation requirements.

Part Context

This part belongs to the ATmega88PA family of high-performance, low-power 8-bit microcontrollers. It shares architectural similarities with other members like the ATMEGA88PA-AU but differs in packaging and reel configuration. The PA designation indicates optimized power consumption compared to standard variants.

Replacement Considerations

ATMEGA88PA-AU offers identical electrical specifications in a 32-TQFP package. ATMEGA88PA-MMH provides the same core functionality in a VFBGA package. Verify pin compatibility and thermal performance before substituting.
