2.3
The CY7C646xx has Control, Bulk, and Interrupt endpoints which each have 64-byte buffers to accommodate the maximum USB
specified packet size, giving the highest USB throughput. One endpoint pair is dedicated to endpoint zero, with separate EP0-IN
and EP0-OUT buffers to simplify programming. Fourteen additional 64-byte buffers may be used as Bulk or Interrupt endpoints.
These endpoints may also be double-buffered by using an endpoint paring mechanism. Double buffering allows the 8051 to
access a packet as another is being transmitted or received over USB. This technique is essential in high-bandwidth applications
where NAKs by the USB function would reduce performance.
The CY7C646xx also has sixteen Isochronous (ISO) endpoints which share 1024 bytes of double-buffered endpoint memory (2
KB total). The ISO buffer sizes are programmable within 16-byte increments. The Isochronous endpoint buffers are accessed as
FIFOs.
