ATMEGA88PB-ANR

Overview

The ATMEGA88PB-ANR is an 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash, 1KB SRAM, and 512B EEPROM. It operates at frequencies up to 20MHz with a supply voltage range of 1.8V to 5.5V. The device includes 27 programmable I/O pins, an 8-channel 10-bit ADC, USART, SPI, and TWI interfaces. It utilizes a 32-pin TQFP package and supports industrial temperature ranges from -40°C to +105°C.

Feature Summary

Supports True Read-While-Write self-programming for continuous code execution during memory updates.
Integrates Core Independent Peripherals allowing background tasks without CPU intervention.
Includes QTouch library support for capacitive touch sensing applications.

Applications

Embedded control systems requiring non-volatile memory updates
Industrial sensor nodes utilizing core-independent peripherals
Consumer devices implementing capacitive touch interfaces

Procurement Notes

Verify the ordering suffix 'ANR' corresponds to the Tape & Reel packaging format as specified in the manufacturer's documentation. Confirm that the speed grade matches the required operational frequency for the target voltage range. Ensure the industrial temperature rating aligns with environmental specifications.

Selection Notes

Select this component when 8KB program memory and 27 I/O lines are sufficient for the application. Consider the TQFP package for standard surface mount assembly processes. Evaluate the need for True Read-While-Write capabilities if bootloader functionality or runtime code updates are required within the design constraints.

Part Context

This part belongs to the ATmega48PB/88PB/168PB family, which introduces Core Independent Peripherals and PicoPower technology. Unlike previous generations, these devices optimize power consumption versus processing speed through advanced RISC architecture. The PB series enhances standard AVR features with additional peripheral flexibility and improved energy efficiency profiles.
