AVR64DA32ST-E/PT

Overview

The AVR64DA32ST-E/PT is an 8-bit microcontroller from the AVR DA series, featuring a 64 kB Flash program memory and 8 kB SRAM. It operates at a maximum clock frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with 14 channels, a 10-bit DAC, three comparators, and a Precision Temperature Comparator (PTC). Connectivity options include six USARTs, two SPI interfaces, and TWI. It utilizes a TQFP-32 package and supports Multi-Voltage I/O (MVIO) for flexible logic levels.

Feature Summary

• Supports multi-voltage I/O (MVIO) for mixed-signal system integration
• Integrates multiple communication peripherals including six USARTs and two SPI controllers
• Features high-resolution analog conversion with a 12-bit ADC and 10-bit DAC

Applications

• Industrial control systems requiring precise analog signal processing
• Smart metering applications utilizing multi-voltage interfaces
• IoT devices needing extensive serial communication capabilities

Procurement Notes

Verify the specific suffix 'ST' against official Microchip documentation to confirm tape-and-reel packaging availability, as standard datasheets may list tube packaging for the base part number. Ensure the operating temperature grade matches the '-E' designation requirements for your specific environmental conditions before finalizing procurement orders.

Selection Notes

Select this component when design requirements demand a high count of serial communication interfaces, specifically six USARTs, within a compact 32-pin form factor. The inclusion of a 12-bit ADC and dedicated comparators makes it suitable for applications involving sensor interfacing and signal conditioning without external support components.

Part Context

This device belongs to the AVR DA family, which emphasizes low power consumption and high performance for 8-bit applications. The series integrates advanced analog peripherals and robust connectivity options, targeting cost-sensitive embedded designs in industrial and consumer markets while maintaining compatibility with existing AVR development tools.

Replacement Considerations

Check for pin-compatible alternatives within the AVR DB or DD series if different peripheral configurations are needed. Verify that substitute parts maintain the same 24 MHz maximum frequency and 1.8 V to 5.5 V operating voltage range to ensure circuit compatibility.
