Overview
The AVR32EA48T-E/6LX is an 8-bit microcontroller from the AVR EA family, featuring a 48-pin VQFN package. It includes 32 KB of Flash memory with read-while-write capability, 4 KB of SRAM, and 512 bytes of EEPROM. The device operates at clock speeds up to 20 MHz and supports a supply voltage range of 1.8 V to 5.5 V. It offers 42 programmable I/O pins and an extended temperature range of -40°C to +125°C.
Feature Summary
- Includes a 12-bit differential ADC with a programmable gain amplifier for high-resolution signal acquisition.
- Features a Configurable Custom Logic (CCL) block with four Look-up Tables for flexible digital logic implementation.
- Supports CPU-independent inter-peripheral signaling through an integrated Event System.
Applications
- Industrial control systems requiring robust analog sensing
- Smart energy metering applications
- Low-power embedded sensor nodes
Procurement Notes
Verify that the 'T' suffix confirms tape and reel packaging and the 'E' suffix indicates the extended temperature rating. Confirm the specific pinout matches the 48-pin VQFN variant. Ensure the ordering code aligns with the preliminary datasheet specifications before finalizing procurement.
Selection Notes
Select this component when extended temperature operation up to 125°C is required alongside standard AVR EA features. It provides vertical migration compatibility within the EA family. Consider the 48-pin count for maximum peripheral availability in compact designs.
Part Context
This part belongs to the AVR32EA28/32/48 series, which shares a common architecture across different pin counts. The 48-pin variant offers the highest number of general-purpose I/O pins and external interrupt capabilities within this specific memory configuration group.
Replacement Considerations
AVR32EA48-I/PT
FAQ
What does the 'T' suffix indicate in the part number?
The 'T' suffix designates that the device is supplied in Tape & Reel packaging format.
Does this device support simultaneous host and client TWI operations?
Yes, the integrated Two-Wire Interface (TWI) supports independent host and client operation on different pins.
