AVR64DB48T-E/PT

Overview

The AVR64DB48T-E/PT 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 +125°C temperatures. Key peripherals include a 12-bit ADC, 10-bit DAC, three op amps, three ZCDs, six USARTs, two SPIs, and two TWIs. It utilizes a TQFP-48 package.

Feature Summary

Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage interfacing.
Includes analog signal conditioning via up to three op amps with internal resistor ladders.
Supports CPU-independent inter-peripheral signaling through the Event System.
Provides automated cyclic redundancy check (CRC) scanning for Flash program memory.

Applications

Industrial control systems requiring extended temperature operation
Power monitoring applications utilizing zero-cross detection
Battery-powered devices needing low-power sleep modes
Smart metering equipment with high-precision analog inputs

Procurement Notes

Verify the 'E' suffix indicates the extended temperature range of -40°C to +125°C. Confirm the 'T' suffix denotes tape and reel packaging. Ensure the 'PT' suffix corresponds to the TQFP-48 package. Cross-reference the manufacturer part number with official Microchip documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component when extended industrial temperature performance is required alongside high peripheral density. The AVR64DB48T-E/PT offers vertical migration compatibility within the AVR DB family without code modification. Consider its multi-voltage I/O capabilities if interfacing with mixed-voltage logic levels is necessary.

Part Context

This device belongs to the AVR DB microcontroller family, which emphasizes low-power architecture and advanced digital peripherals. The AVR64DB series provides pin-and-feature compatibility across varying pin counts, allowing for scalable design transitions. It integrates precise analog subsystems and event-driven processing to reduce CPU load in complex embedded applications.
