Question: What is the difference between the CY7C68000 and the CY7C68000A?
Essentially they are both high speed USB 2.0 UTMI transceivers. They are built on the same process and have the same functionality. Both are compliant with the USB 2.0 Transceiver Macrocell Interface (UTMI) standard. They both also offer low suspend current at just 15 micro amps. The differences between the two stem from the end products that they are intended for. Cypress's MoBL-USB TX2 (CY7C68000A) high-speed USB 2.0 transceiver is offered in a 56-ball VFBGA (5mm x 5mm) and a 56-pin QFN package (8mm x 8mm) making it ideal for such applications as mobile phones, PDAs, smart phones, portable media players (PMP), and handheld global positioning systems (GPS). Also, the UTMI interface timing has been optimized to interface with the Intel Monahans Processor and as such was endorsed and chosen by Intel for use on the Intel?s Zylonite Development System PDK for the Monahans. The timing parameters, namely Tcsu_min and Tdsu_min, have been changed to accommodate the tight timing requirements of the Intel Monahans -P/L Application Processors. The EZ-USB TX2 (CY7C68000) is Cypress' first high-speed USB 2.0 transceiver. It is ideal for products with high speed USB requirements, which use a standard UTMI interface and do not require a small VFBGA package, such as set-top boxes, medical devices, and networking devices. Also, it is not compatible with the Intel Monahans Processor. The TX2 is currently obsolete. Check the link here for active cypress peripheral transceivers.
