Overview
The AVR32DB48T-E/6LX is an 8-bit microcontroller from the AVR DB family, featuring a 32 KB Flash program memory, 4 KB SRAM, and 512 bytes of EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC, 10-bit DAC, three analog comparators, two zero-cross detectors, and three op amps. It utilizes a 48-pin VQFN package (suffix 6LX) and supports extended temperature operation from -40°C to +125°C.
Feature Summary
- Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage interfacing
- Includes Configurable Custom Logic (CCL) with programmable Look-up Tables
- Supports CPU-independent inter-peripheral signaling via Event System
- Integrates automated CRC scan for Flash program memory verification
Applications
- Industrial control systems requiring robust analog signal processing
- Power management applications utilizing zero-cross detection
- Embedded devices needing multi-voltage I/O compatibility
- Cost-sensitive designs requiring vertical migration within the AVR DB family
Procurement Notes
Verify the ordering suffix '6LX' corresponds to the VQFN48 package type as defined in the datasheet designation table. Confirm the 'E' suffix indicates the extended temperature range (-40°C to +125°C). Ensure the 'T' suffix matches the required tape and reel carrier type for your manufacturing process. Cross-reference the specific part number against the official Microchip product page to confirm current availability and revision status.
Selection Notes
Select this component when a 48-pin footprint is required alongside extended temperature capabilities. The AVR32DB48 offers full pin and feature compatibility with other AVR DB devices, allowing for vertical migration without code modification. Consider the integrated analog subsystem, including op amps and ZCDs, if signal conditioning or power control features are needed without external components.
Part Context
This part belongs to the AVR32DB28/32/48 series, which shares a common architecture with 32 KB Flash and 4 KB SRAM. It is designed for low-power applications using the AVR CPU with a hardware multiplier. The device supports single-pin UPDI programming and offers multiple sleep modes for power optimization.
Replacement Considerations
AVR32DB48T-I/6LX: Same package and memory but industrial temperature range (-40°C to +85°C). AVR32DB48-E/PT: Extended temperature range but TQFP-48 package instead of VQFN.
