AVR64DB28-I/SP

Overview

The AVR64DB28-I/SP is an 8-bit microcontroller from the AVR DB family, featuring a 28-pin SPDIP package and industrial temperature range (-40°C to +85°C). It integrates 64 KB of Flash memory, 8 KB of SRAM, and 512 bytes of EEPROM. The device operates at clock speeds up to 24 MHz with a supply voltage range of 1.8V to 5.5V. Key peripherals include a 12-bit ADC, three analog comparators, one 10-bit DAC, three zero-cross detectors, and multiple communication interfaces such as USART, SPI, and TWI.

Feature Summary

Multi-Voltage I/O (MVIO) capability on Port C for flexible logic level interfacing
Integrated Analog Signal Conditioning subsystem with op amps and internal resistor ladders
Configurable Custom Logic (CCL) providing programmable Look-up Tables for custom digital functions
Event System enabling CPU-independent inter-peripheral signaling

Applications

Industrial control systems requiring robust analog signal processing
Power management applications utilizing zero-cross detection
Embedded devices needing multi-voltage I/O compatibility
Cost-sensitive automation controllers using the AVR DB architecture

Procurement Notes

Verify the ordering suffix 'I' confirms the industrial temperature range of -40°C to +85°C. Confirm the '/SP' suffix indicates the SPDIP package style. Ensure the base part number matches the specific memory configuration required for your design constraints before finalizing procurement.

Selection Notes

Select this component when a 28-pin through-hole solution is required for the AVR DB family. It provides vertical migration compatibility within the family without code modification. Consider the extended temperature variant if operation above 85°C is necessary. Verify that the 64 KB Flash size meets application storage needs compared to smaller or larger variants.

Part Context

This device belongs to the AVR DB microcontroller family, which emphasizes low-power architecture and advanced analog peripherals. The family supports vertical migration across pin counts and memory sizes while maintaining feature compatibility. The AVR64DB28 represents the 28-pin, 64 KB Flash entry point in this specific series.
