AVR64DB28T-E/SS

Overview

The AVR64DB28T-E/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 in a 28-pin SSOP package. Key peripherals include a 12-bit ADC with 13 channels, three op amps, three zero-cross detectors, a 10-bit DAC, and multiple communication interfaces (USART, SPI, TWI). Operating voltage ranges from 1.8 V to 5.5 V across -40°C to +125°C.

Feature Summary

Multi-Voltage I/O (MVIO) capability on Port C for flexible logic level interfacing
Integrated analog subsystems including three op amps and three zero-cross detectors
Event System enables CPU-independent peripheral signaling for predictable timing
Configurable Custom Logic (CCL) provides programmable look-up tables

Applications

Industrial control systems requiring multi-voltage operation
Home appliances with AC mains sensing via zero-cross detection
IoT devices utilizing low-power sleep modes and event-driven processing
Motor control applications using optimized PWM timers and analog comparators

Procurement Notes

Verify the ordering suffix 'E' confirms extended temperature range (-40°C to +125°C) and 'SS' indicates the SSOP-28 package. Confirm 'T' denotes tape and reel packaging. Cross-reference the datasheet DS40002300B for specific pinout and electrical characteristics relevant to your design constraints.

Selection Notes

Select this part when vertical migration within the AVR DB family is required without code modification. Choose this model if 64 KB Flash and 8 KB SRAM are necessary alongside specific analog features like three op amps or three ZCDs. Ensure the 28-pin form factor fits the board layout compared to larger pin-count variants.

Part Context

This component belongs to the AVR® DB microcontroller family, which utilizes the latest Microchip technologies for flexible, low-power architectures. The family supports horizontal and vertical migration between different pin counts and memory sizes while maintaining feature compatibility.
