AVR64DB64T-I/PT

Overview

The AVR64DB64T-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 55 programmable I/O pins in a TQFP-64 package. Key peripherals include a 12-bit ADC with 22 channels, three analog comparators, three zero-cross detectors, a 10-bit DAC, and three op amps. Communication interfaces consist of six USARTs, two SPIs, and two TWI/I2C modules. Operating voltage ranges from 1.8 V to 5.5 V, with an industrial temperature range of -40°C to +85°C.

Feature Summary

Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage level interfacing.
Includes an Event System for CPU-independent peripheral signaling and Configurable Custom Logic (CCL).
Integrates Analog Signal Conditioning with up to three op amps and internal resistor ladders.
Supports automated cyclic redundancy check (CRC) scanning for Flash program memory.

Applications

Industrial control systems requiring robust analog signal processing.
Smart energy metering applications utilizing zero-cross detection.
Motor control designs leveraging optimized PWM timers and event systems.
Secondary monitoring devices needing secure non-volatile data retention.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding pin count and peripheral availability. Cross-reference the datasheet revision number to validate feature sets and electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when high pin density and advanced analog capabilities are required within an 8-bit architecture. The AVR DB family allows vertical migration without code modification, facilitating future scalability. Consider the integrated op amps and zero-cross detectors if external components can be eliminated to reduce board space and cost.

Part Context

This part belongs to the AVR DB family, which utilizes the latest Microchip technologies for low-power operation. The family supports horizontal and vertical migration across different pin counts and memory sizes while maintaining pin and feature compatibility. This specific model represents the 64-pin variant with 64 KB of Flash memory.
