Overview
The AVR32DA48S-E/PT is an 8-bit microcontroller from Microchip Technology's AVR DA series. It features a 24 MHz CPU, 32 KB of Flash memory, and 4 KB of RAM. The device is housed in a 48-pin TQFP package with 27 I/O lines. Key peripherals include a 12-bit ADC, three comparators, PTC, ZCD, DAC, UART, SPI, and TWI interfaces. It supports PDID and operates within a voltage range of 1.8 V to 5.5 V.
Feature Summary
- Integrates high-performance analog peripherals including a 12-bit ADC and multiple comparators for precise signal processing.
- Supports capacitive touch sensing via the Peripheral Touch Controller (PTC) for intuitive user interface applications.
- Provides flexible communication options through integrated UART, SPI, and TWI modules for system connectivity.
Applications
- Industrial control systems requiring real-time processing
- Smart home appliances with touch interface capabilities
- IoT devices needing low-power wireless communication stacks
Procurement Notes
Verify the specific suffix 'S' indicates the standard commercial temperature grade variant when sourcing. Confirm the package type matches the required PCB footprint. Ensure the ordering code aligns with the exact memory configuration and peripheral set defined in the official datasheet to avoid functional mismatches during integration.
Selection Notes
Select this component for applications requiring a balance of analog precision and digital control in a compact form factor. The 24 MHz speed suits moderate throughput needs. Consider the 12-bit ADC resolution for sensor interfacing. Evaluate pin count adequacy for I/O requirements before finalizing the design architecture.
Part Context
This part belongs to the AVR DA family, designed for low-power performance and real-time control. It combines independent core peripherals with smart analog features. The series targets applications demanding high memory density and efficient peripheral handling for both standalone and companion MCU roles.
Replacement Considerations
AVR32DA48ST-E/6MX offers identical specifications in a VQFN package. AVR32DA48-I/PT provides the same core functionality in a standard TQFP package with industrial temperature rating. Verify package compatibility and temperature range differences when substituting.
