Procurement Notes

This component is explicitly marked as not recommended for new designs. Engineers should verify availability through authorized distributors and consider the AT97SC3205T as the designated replacement for future projects to ensure long-term supply chain stability.

Selection Notes

Select this part only for legacy system maintenance or existing designs utilizing the AT97SC3204T family. For new implementations, the AT97SC3205T is the required alternative. Ensure the design supports the TWI interface and accommodates the 40ML1 package footprint.

Part Context

The AT97SC3204T series was originally developed by Atmel Corporation before its acquisition by Microchip Technology. The 'T' suffix denotes the TWI (I²C) interface variant, distinguishing it from the LPC-based AT97SC3204. The product line transitioned from Atmel branding to Microchip Technology following corporate integration.

Replacement Considerations

The AT97SC3205T is the officially documented replacement for the AT97SC3204T series. Designers must evaluate pin compatibility and software migration requirements when transitioning from the obsolete AT97SC3204T to the AT97SC3205T.
