• Includes Configurable Custom Logic (CCL) with programmable Look-up Tables for custom digital logic implementation.
• Supports CPU-independent peripheral signaling via the Event System.
• Integrates Analog Signal Conditioning peripherals with op amps and internal resistor ladders.

Applications

• Industrial control systems requiring robust analog signal processing.
• Smart energy metering applications utilizing high-resolution ADCs.
• Motor control designs leveraging PWM timers and zero-cross detectors.
• Low-power embedded devices using configurable sleep modes.

Procurement Notes

Verify the specific ordering suffix '6LX' corresponds to the VQFN-48 package type when sourcing components. Confirm that the 'T' suffix indicates tape and reel packaging for automated assembly processes. Ensure the 'I' designation matches the required industrial temperature range specifications for your operational environment. Cross-reference the datasheet revision DS40002301B for any updates regarding pinout or electrical characteristics.

Selection Notes

Select this component when vertical migration within the AVR DB family is required without code modification. Consider this part if the design demands a balance of analog peripherals like OPAMPs and ZCDs alongside standard digital interfaces. Evaluate the 48-pin count against available PCB space and I/O requirements compared to smaller variants in the series.

Part Context

This microcontroller belongs to the AVR32DB28/32/48 series, which shares architectural compatibility across pin counts. It represents the 48-pin variant offering expanded I/O capabilities while maintaining the same core memory and peripheral structure as its 28-pin and 32-pin counterparts. This allows for scalable product development within the same ecosystem.

Replacement Considerations

AVR32DB48T-E/6LX offers extended temperature range options. AVR32DB48-I/PT provides the same functionality in a TQFP package. AVR64DB48T-I/6LX provides increased memory capacity within the same package.
