EZ-USB FX2LP™/AT2LP™ Reset and Power Considerations - AN064

Last Updated: 07/18/2012
Many designers have had difficulty with the reset and power needs of the FX2LP and the USB specification. This Application Note addresses the main areas where USB and FX2LP designs have special needs.

The Cypress EZ-USB FX2LP(TM) is a USB 2.0 high-speed device. It contains an 8051, 16K of program/data memory, 4K of endpoint buffers and a General Programmable Interface (GPIF) block. The EZ-USB AT2LP(TM) is a USB 2.0 high-speed ATA/ATAPI bridge chip. Both these chips have similar power and reset needs. This application note refers to the FX2LP, but is also applicable to AT2LP.
