Overview
The AVR64DA64T-E/PT is a 64-pin microcontroller from the AVR DA family, utilizing an AVR CPU with hardware multiplier running at up to 24 MHz. It features 64 KB of Flash memory, 8 KB of SRAM, and 512 B of EEPROM. The device includes a 12-bit differential ADC with 22 channels, three analog comparators, one 10-bit DAC, and up to six USARTs. It supports extended temperature operation from -40°C to +125°C and is supplied in a TQFP package.
Feature Summary
- Supports vertical migration within the AVR DA(S) family without code modification due to full pin and feature compatibility.
- Includes advanced digital peripherals such as Configurable Custom Logic (CCL) with programmable Look-up Tables and an Event System for inter-peripheral signaling.
- Features a Peripheral Touch Controller (PTC) with Driven Shield+ technology for capacitive touch applications.
Applications
- Real-time control systems requiring high-speed processing
- Sensor nodes utilizing capacitive touch interfaces
- Secondary security monitoring devices
Procurement Notes
Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'PT' indicates the TQFP package style. Confirm the 'T' suffix denotes tape and reel packaging. Ensure the specific part number matches the required voltage range and peripheral configuration before finalizing procurement.
Selection Notes
Select this component when a 64-pin form factor is required alongside extensive I/O capabilities and advanced analog features. It is suitable for designs needing vertical migration flexibility within the AVR DA family. Consider the extended temperature rating if the application operates in harsh environments beyond standard industrial limits.
Part Context
This device belongs to the AVR64DA28/32/48/64(S) series, which shares a common architecture and instruction set. The AVR DA family integrates intelligent analog features and low-power modes. The 64-pin variant offers the highest peripheral count in the 64 KB Flash segment of this series.
Replacement Considerations
AVR64DA64-I/PT provides the same specifications but with an industrial temperature range (-40°C to +85°C). Other AVR64DA64 variants are available in different packages such as VQFN or SPDIP depending on board layout requirements.
