AVR64DA64S-I/PT

Overview

The AVR64DA64S-I/PT is an 8-bit microcontroller from Microchip Technology, based on the AVR core. It features 64 kB of Flash program memory and 8 kB of SRAM data memory. The device operates at a maximum clock frequency of 24 MHz and supports a supply voltage range of 1.8 V to 5.5 V. It is housed in a TQFP-64 package with 55 available I/O pins. Key peripherals include a 12-bit ADC with 22 channels, a 10-bit DAC, three comparators, and multiple communication interfaces such as USART, SPI, and TWI.

Feature Summary

• Integrates a 12-bit Analog-to-Digital Converter (ADC) with up to 22 input channels for high-resolution signal acquisition.
• Includes a 10-bit Digital-to-Analog Converter (DAC) for analog output generation.
• Features three internal analog comparators for fast threshold detection applications.
• Supports multiple serial communication protocols including USART, SPI, and TWI.

Applications

• Industrial control systems requiring robust 8-bit processing
• Sensor interface modules utilizing high-resolution ADC inputs
• General-purpose embedded applications within industrial temperature ranges

Procurement Notes

Verify the specific suffix 'S' against official Microchip documentation to confirm package or variant details, as standard listings often reference the 'AVR64DA64T-I/PT'. Ensure the operating temperature grade matches the '-I' designation for industrial applications. Cross-reference the datasheet for pinout compatibility if substituting other devices in the AVR64DA series.

Selection Notes

Select this component when a balance of moderate I/O count and high-resolution analog capabilities is required in a 64-pin form factor. The 24 MHz speed suits applications not demanding higher throughput but needing efficient power management. Consider the availability of the TQFP-64 package for surface-mount assembly constraints.

Part Context

This part belongs to the AVR64DA family, which provides enhanced peripheral sets compared to older AVR architectures. The DA series integrates advanced analog blocks like the 12-bit ADC and comparators directly into the MCU, reducing external component count for sensor-based designs.
