AVR64DB28T-I/SS

Overview

The AVR64DB28T-I/SS is an 8-bit microcontroller from the AVR DB family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB Flash, 8 KB SRAM, and 512 B EEPROM. The device operates within a 1.8 V to 5.5 V supply range and supports -40°C to +85°C temperatures. Key peripherals include a 12-bit ADC with 13 channels, three op amps, three ZCDs, a 10-bit DAC, four timers, USART, SPI, and TWI interfaces. It utilizes a 28-pin SSOP package.

Feature Summary

Multi-Voltage I/O (MVIO) on Port C for flexible voltage threshold selection
Analog signal conditioning with up to three op amps and internal resistor ladders
Event System for CPU-independent inter-peripheral signaling
Configurable Custom Logic (CCL) with programmable Look-up Tables

Applications

Embedded control systems requiring analog signal processing
Power control applications utilizing Zero-Cross Detectors
Industrial communication nodes using USART, SPI, or TWI
Battery-powered devices supported by low-power sleep modes

Procurement Notes

Verify the ordering suffix 'T' indicates Tape & Reel packaging and 'I' specifies Industrial temperature range (-40°C to +85°C). Confirm the 'SS' suffix corresponds to the SSOP-28 package style. Ensure compatibility with existing designs as the device maintains pin and feature compatibility within the AVR DB family.

Selection Notes

Select this part for designs requiring 64 KB of program memory and 13 ADC channels in a compact 28-pin form factor. Consider the extended peripheral set including multiple timers and analog comparators if complex signal conditioning is needed. Verify that the 1.8V to 5.5V operating range meets system power requirements.

Part Context

This component belongs to the AVR64DB28/32/48/64 series within the broader AVR DB microcontroller family. It shares architectural similarities with other members like the AVR32DB28 and AVR128DB28, differing primarily in memory size and pin count. The family supports vertical migration without code modification.
