AVR64DA48-E/PT

Overview

The AVR64DA48-E/PT is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB of self-programmable Flash memory, 8 KB of SRAM, and 512 B of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an extended industrial temperature range of -40°C to +125°C. Key peripherals include up to six USARTs, two SPI interfaces, two TWI/I2C controllers, a 12-bit ADC, a 10-bit DAC, three analog comparators, and a Peripheral Touch Controller.

Feature Summary

• Supports vertical migration without code modification across the AVR DA(S) family due to full pin and feature compatibility.
• Integrates intelligent analog features including a 12-bit differential ADC, 10-bit DAC, and three analog comparators with window compare functions.
• Includes a Peripheral Touch Controller (PTC) utilizing Driven Shield+ and Boost Mode technologies for capacitive touch applications.
• Features a Configurable Custom Logic (CCL) block with programmable Look-up Tables for independent peripheral signaling.

Applications

• Capacitive touch interface designs using buttons, sliders, wheels, or 2D surfaces.
• Power control systems requiring optimized Timer/Counter type D (TCD) functionality.
• Industrial communication nodes utilizing multiple USART, SPI, and TWI/I2C interfaces.
• Applications requiring secure firmware upgrades via Program and Debug Interface Disable (PDID).

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) as specified in the datasheet. Confirm the package style 'PT' matches the required TQFP form factor. Ensure the specific revision of the datasheet DS40002233C is referenced for accurate electrical characteristics and timing parameters during final validation.

Selection Notes

Select this component when an 8-bit AVR architecture with high peripheral density is required. The 48-pin TQFP package offers a balance between I/O count and physical footprint. Consider the extended temperature rating if operation exceeds standard industrial limits. Verify that the 64 KB Flash and 8 KB SRAM meet application memory requirements before choosing over smaller or larger variants in the DA series.

Part Context

This part belongs to the AVR64DA28/32/48/64(S) microcontroller family. It shares the same core CPU and peripheral set as other devices in the series, differing primarily in pin count and available I/O resources. The 'DA' designation indicates the inclusion of advanced features like the Peripheral Touch Controller and enhanced analog subsystems compared to older AVR families.
