AVR64DB48T-I/PT

Overview

The AVR64DB48T-I/PT is an 8-bit microcontroller from the AVR DB family, featuring a hardware multiplier CPU running at up to 24 MHz. It includes 64 KB of Flash, 8 KB of SRAM, and 512 bytes of EEPROM. The device offers 41 I/O pins in a TQFP-48 package with a supply voltage range of 1.8 V to 5.5 V. Key peripherals include a 12-bit ADC, three op amps, three zero-cross detectors, and multiple communication interfaces.

Feature Summary

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

Applications

Industrial control systems requiring robust peripheral integration
Power control applications utilizing zero-cross detection and PWM timers
Battery-powered devices benefiting from low-power architecture

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature rating. Ensure the component matches the required industrial grade specifications for your application environment. Cross-reference datasheet revision numbers to guarantee accurate pinout and electrical parameter alignment during procurement.

Selection Notes

Select this model when vertical migration within the AVR DB family is required without code modification. Consider the 48-pin TQFP package for higher I/O density compared to smaller variants. Evaluate the need for MVIO capabilities and advanced analog peripherals like op amps and ZCDs before choosing over standard AVR counterparts.

Part Context

This component belongs to the AVR64DB28/32/48/64 series, designed for full pin and feature compatibility across the family. It utilizes the latest AVR DB technologies, including a flexible low-power architecture and accurate analog subsystems. The device supports horizontal migration to reduce pin counts while maintaining core functionality.
