AVR64DA48T-E/PT

Overview

The AVR64DA48T-E/PT is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz CPU, 64 KB Flash, 8 KB SRAM, and 512 B EEPROM. It includes a 12-bit ADC with 18 channels, three analog comparators, one DAC, six USARTs, two SPIs, and two TWIs. The device supports Peripheral Touch Controller (PTC) technology and operates within a -40°C to +125°C temperature range in a TQFP-48 package.

Feature Summary

• Integrates intelligent analog features including a 12-bit differential ADC, three analog comparators, and a 10-bit DAC for precise signal processing.
• Supports capacitive touch applications via the Peripheral Touch Controller (PTC) with Driven Shield+ and Boost Mode technologies.
• Provides flexible communication interfaces including up to six USARTs, two SPIs, and dual-mode TWI/I2C controllers.
• Features a secure architecture with Program and Debug Interface Disable (PDID) capabilities for firmware authentication.

Applications

• Smart home appliances requiring capacitive touch controls
• Industrial motor control systems utilizing zero-cross detection
• Battery-powered devices leveraging low-power sleep modes

Procurement Notes

Verify that the ordering suffix 'E' confirms the extended industrial temperature range of -40°C to +125°C. Confirm the 'T' suffix indicates tape and reel packaging rather than tube or tray formats. Ensure compatibility with the UPDI programming interface for development and production flashing.

Selection Notes

Select this component when high pin count (48 pins) and extensive peripheral availability are required. The extended temperature rating makes it suitable for harsh environments. Consider vertical migration within the AVR DA family if future memory scaling is needed without code modification.

Part Context

This part belongs to the AVR DA(S) family, which combines the AVR CPU with intelligent analog peripherals and the Peripheral Touch Controller. The family emphasizes low power consumption and real-time control capabilities, supporting both standalone operation and integration into complex embedded systems.

Replacement Considerations

AVR64DA48-I/PT offers identical functionality but with an industrial temperature range (-40°C to +85°C).
