Overview
The AVR128DA64-E/PT is an 8-bit microcontroller from the AVR® DA family, featuring a 24 MHz CPU with hardware multiplier. It includes 128 KB Flash, 16 KB SRAM, and 512 B EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an extended temperature range of -40°C to +125°C. It provides up to 55 programmable I/O pins in a TQFP-64 package.
Feature Summary
- Integrates intelligent analog features including a 12-bit differential ADC, three analog comparators, and zero-cross detectors for precise signal processing.
- Supports capacitive touch applications via the Peripheral Touch Controller (PTC) with Driven Shield+ technology.
- Enables low-power operation through multiple sleep modes and auto-tuning internal oscillators.
- Features a flexible Event System for predictable inter-peripheral signaling without CPU intervention.
Applications
- Wired and wireless communication stack implementations
- Capacitive touch user interfaces
- Power control systems utilizing Timer/Counter type D
- Industrial monitoring requiring high-precision analog measurements
Procurement Notes
Verify that the ordering suffix 'E' confirms the extended temperature rating (-40°C to +125°C). Confirm the 'PT' suffix corresponds to the TQFP-64 package. Ensure the component matches the official Microchip datasheet DS40002183B specifications before integration.
Selection Notes
Select this model when vertical migration within the AVR DA family is required without code modification. Choose this variant over lower pin-count devices if more than 41 general-purpose I/O pins are necessary. Consider the 12-bit ADC resolution and PTC capabilities for applications demanding advanced sensing.
Part Context
This component belongs to the AVR128DA28/32/48/64 series, which shares full pin and feature compatibility for vertical migration. The 64-pin variant offers the highest peripheral count within this specific memory density group, including up to six USARTs and two TWI interfaces.
Replacement Considerations
AVR128DA64-I/PT serves as the industrial temperature rated alternative. Other AVR DA family members offer horizontal migration options with reduced pin counts but maintain software compatibility.
FAQ
Does the AVR128DA64 support simultaneous master and slave operation on TWI?
Yes, the TWI/I2C interface can operate simultaneously as master and slave on different pins.
What is the maximum clock frequency for the AVR128DA64?
The device runs at up to 24 MHz using the High-Precision internal high-frequency Oscillator (OSCHF).
How many self-capacitance channels does the PTC provide?
The Peripheral Touch Controller provides up to 46 self-capacitance channels.
