ATMEGA88PB-MU

Overview

The ATMEGA88PB-MU is an 8-bit AVR microcontroller featuring 8 KB of in-system programmable Flash, 1 KB SRAM, and 512 bytes EEPROM. It operates at a maximum frequency of 20 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 10-bit ADC with 8 channels, six PWM outputs, and standard communication interfaces including SPI, TWI (I²C), and USART. It is housed in a 32-pin VFQFN package.

Feature Summary

Supports True Read-While-Write self-programming for continuous code execution during memory updates.
Integrates QTouch library capabilities for capacitive touch sensing applications.
Provides multiple power-saving modes including Power-down and Idle to optimize energy consumption.
Features Core Independent Peripherals allowing background tasks without CPU intervention.

Applications

Embedded control systems requiring low-power operation
Capacitive touch interface implementations
Industrial sensor nodes
Battery-powered portable devices

Procurement Notes

Verify the specific speed grade and operating temperature range required for your application against the datasheet specifications. Confirm that the 32-VFQFN package dimensions match your PCB footprint design. Ensure compatibility with your programming interface for In-System Programming (ISP) before finalizing procurement.

Selection Notes

Select this component when 8 KB of program memory is sufficient for your firmware requirements. Consider the 20 MHz maximum clock speed for processing performance needs. Evaluate the 1.8V to 5.5V operating voltage range against your system's power supply constraints. Verify that the 32-pin VFQFN package is suitable for your manufacturing process.

Part Context

This part belongs to the ATmega48PB/88PB/168PB family, which shares a common architecture but differs in memory sizes. The ATMEGA88PB-MU specifically provides 8 KB of Flash, distinguishing it from the 4 KB ATmega48PB and 16 KB ATmega168PB variants while maintaining identical peripheral sets and pinouts.
