Overview
The AVR64DA48T-I/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 utilizes a TQFP-48 package with an industrial temperature range of -40°C to +85°C. Key peripherals include a 12-bit ADC, three analog comparators, one DAC, up to six USARTs, two SPIs, and two TWIs. The device supports UPDI programming and includes advanced features like the Peripheral Touch Controller (PTC), Configurable Custom Logic (CCL), and an Event System.
Feature Summary
- Integrates a Peripheral Touch Controller (PTC) supporting driven shield and boost modes for capacitive touch applications.
- Features a flexible Event System enabling CPU-independent inter-peripheral signaling for predictable execution.
- Includes Configurable Custom Logic (CCL) with programmable Look-up Tables for custom digital logic implementation.
Applications
- Capacitive touch interface designs using buttons, sliders, or wheels
- Industrial control systems requiring robust peripheral communication
- Smart home and IoT devices needing low-power operation
Procurement Notes
Verify the specific ordering suffix 'T' indicates tape and reel packaging when sourcing components. Confirm that the 'I' suffix corresponds to the required industrial temperature range (-40°C to +85°C). Ensure compatibility with the TQFP-48 footprint during PCB layout verification.
Selection Notes
Select this component for applications requiring high pin counts within a 48-pin form factor. Consider the AVR DA family's vertical migration capabilities if future memory expansion is anticipated without code modification. Evaluate the PTC and CCL features against simpler logic requirements to optimize cost.
Part Context
This part belongs to the AVR64DA28/32/48/64(S) series, designed for vertical migration within the AVR DA family. It shares architectural similarities with other members but offers specific memory and I/O configurations suited for mid-range embedded control tasks.
Replacement Considerations
AVR64DA48-I/PT serves as a non-tape-and-reel alternative within the same package and specification profile.
FAQ
Does the AVR64DA48T-I/PT support the Peripheral Touch Controller?
Yes, it includes a Peripheral Touch Controller (PTC) capable of handling self-capacitance and mutual capacitance channels.
What is the maximum operating frequency of this microcontroller?
The AVR CPU runs at a maximum frequency of 24 MHz.
