Note:
Document #: 38-02043 Rev. *B
1.
• The hardware interface to the NDC uses an SSRAM interface. The CYNCP80192 device supports ZBT
• All instructions and/or responses are mapped into the SSRAM address (ADR) space.
• The CYNCP80192 device provides simultaneous multiple layer, variable-width tables (×68, ×136, ×272).
• There is support for table sizes up to four million ×34 entries.
• There are 33 million searches per second (Msps) in the ×68 configuration (CFG).
• The CYNCP80192 device is compatible with 1-Mb, 2-Mb, and 4-Mb NSEs.
• It has a glueless interface to industry standard synchronous SRAMs and NSEs.
• The CYNCP80192 device uses up to 100 MHz master clock frequency.
• It has an IEEE 1149.1 test access port.
• There is a 2.5V/3.3V power supply and a 388-pin BGA package.
