ATMEGA88PB-AN

Overview

The ATMEGA88PB-AN 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 27 I/O pins, an 8-channel 10-bit ADC, USART, SPI, and TWI interfaces. It utilizes a 32-pin TQFP package and supports industrial temperatures from -40°C to +105°C.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Supports QTouch library for capacitive touch sensing applications including buttons and sliders.
• Features True Read-While-Write capability allowing code execution while flash memory is being reprogrammed.

Applications

• Embedded control systems requiring low power consumption
• Capacitive touch interface implementations
• Industrial monitoring devices operating in wide temperature ranges

Procurement Notes

Verify the specific speed grade required for your application voltage conditions. Confirm that the 32-pin TQFP package matches your PCB footprint design. Ensure compatibility with existing development tools such as C compilers or debuggers. Check for any specific revision errata relevant to early production batches before finalizing procurement plans.

Selection Notes

Select this model when 8 KB program memory is sufficient compared to the 4 KB ATmega48PB variant. Choose the AN suffix specifically for the 32-lead TQFP package format. Consider the PB series over older variants if Core Independent Peripherals or QTouch support are necessary requirements for the design.

Part Context

This component belongs to the ATmega48PB/88PB/168PB family, which shares identical pinouts and peripheral sets. The primary distinction between these family members lies in their non-volatile memory capacities and interrupt vector sizes. This specific part provides a middle-ground memory configuration within the series.
