Overview
The AVR32DA48ST-E/6MX is an 8-bit microcontroller from Microchip Technology's AVR DA series, featuring a high-performance AVR CPU core with hardware multiplication. It integrates 32KB of system-in-programmable flash memory and 4KB of SRAM. The device supports clock speeds up to 24MHz and operates within a voltage range of 1.8V to 5.5V. Key peripherals include a 12-bit ADC, multiple UARTs, SPI, and TWI interfaces, alongside analog comparators and a DAC.
Feature Summary
- Integrates a flexible and low-power architecture with an event system for precise timing and signal processing.
- Includes advanced analog subsystems such as a 12-bit ADC with programmable gain amplifier and window comparators.
- Features configurable custom logic (CCL) allowing for up to four programmable look-up tables to implement hardware-based solutions.
Applications
- Industrial control systems requiring robust analog sensing and communication
- Smart home devices utilizing low-power operation and event-driven processing
- Sensor nodes employing I2C and UART connectivity for data acquisition
Procurement Notes
Verify the specific suffix 'ST' against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the '-E' designation aligns with the required extended temperature range for your application environment. Cross-reference the full part number with the manufacturer's current datasheet to confirm pinout compatibility and peripheral availability before finalizing procurement.
Selection Notes
Select this component when an 8-bit AVR solution with high-speed analog capabilities and configurable logic is required. It is suitable for designs needing multiple communication interfaces and precise timing without the complexity of 32-bit architectures. Consider the 48-pin form factor for increased I/O density compared to smaller packages in the same series.
Part Context
This part belongs to the AVR DA family, which combines the proven AVR instruction set with enhanced analog and digital peripherals. The series is designed for applications demanding high performance and low power consumption, offering features like the Event System and Configurable Custom Logic to reduce CPU load and improve response times in embedded control tasks.
Replacement Considerations
Direct substitutes within the AVR DA series include AVR32DA28, AVR32DA32, and AVR32DA64 variants, depending on pin count and memory requirements. Verify that alternative packages maintain the same electrical characteristics and peripheral sets for seamless integration.
