Overview
The AVR32DA32S-I/QZB is an 8-bit microcontroller from Microchip Technology featuring a 32 KB Flash program memory and 4 KB RAM. It utilizes a VQFN-32 package with 32 pins and operates at a maximum clock frequency of 24 MHz. The device supports a supply voltage range of 1.8 V to 5.5 V and includes a 12-bit ADC, three comparators, a DAC, and multiple communication interfaces including UART, SPI, and TWI.
Feature Summary
- Integrates a 12-bit analog-to-digital converter for precise signal acquisition.
- Includes three built-in comparators for fast response applications.
- Features a programmable digital interface (PDID) for flexible connectivity.
- Supports zero-cross detection (ZCD) for AC line monitoring.
Applications
- Smart metering systems requiring accurate energy measurement
- Industrial control units utilizing zero-cross detection
- Embedded sensor nodes with analog input requirements
Procurement Notes
Verify the specific suffix QZB corresponds to the VQFN-32 tray packaging configuration as listed in distributor catalogs. Confirm the operating temperature range matches industrial specifications (-40°C to +85°C). Ensure the component is sourced from authorized channels to guarantee authenticity and traceability for production environments.
Selection Notes
Select this model when a compact VQFN footprint is required alongside high peripheral density. It is suitable for designs needing multiple analog inputs and digital comparison capabilities within a small form factor. Consider the 24 MHz processing speed against power consumption constraints typical of 8-bit AVR architectures.
Part Context
This part belongs to the AVR32 DA series, designed for cost-sensitive embedded applications. It shares architectural similarities with other DA family members but offers a specific pin count and package type optimized for space-constrained PCB layouts while maintaining compatibility with standard development tools.
Replacement Considerations
AVR32DA32-I/PT is a pin-compatible alternative in a TQFP-32 package. AVR32DA32T-I/PT offers the same core functionality in a tape-and-reel format. Verify package dimensions and thermal characteristics before substitution.
