PRELIMINARY  
CY7C1326  
128K x 18 Synchronous-Pipelined Cache RAM  
Features  
Functional Description  
• Low (1.65 mW) standby power (f=0, L version)  
The CY7C1326 is a 3.3V 128K by 18 synchronous-pipelined  
cache SRAM designed to support zero wait state secondary  
cache with minimal glue logic.  
• Supports 100-MHz bus for Pentium® and PowerPC™  
operations with zero wait states  
All synchronous inputs pass through input registers controlled  
by the rising edge of the clock. All data outputs pass through  
output registers controlled by the rising edge of the clock. Max-  
imum access delay from the clock rise is 3.5 ns (166-MHz  
device). A 2-bit on-chip wraparound burst counter captures the  
first address in a burst sequence and automatically increments  
the address for the rest of the burst access.  
• Fully registered inputs and outputs for pipelined  
operation  
• 128K x 18 common I/O architecture  
• Single 3.3V power supply  
• Fast clock-to-output times  
— 3.5 ns (for 166-MHz device)  
— 4.0 ns (for 133-MHz device)  
— 4.5 ns (for 117-MHz device)  
— 5.5 ns (for 100-MHz device)  
The CY7C1326 supports either the interleaved burst se-  
quence used by the Intel Pentium processor or a linear burst  
sequence used by processors such as the PowerPC. The burst  
sequence is selected through the MODE pin. Accesses can be  
initiated by asserting either the processor address strobe  
(ADSP) or the controller address strobe (ADSC) at clock rise.  
Address advancement through the burst sequence is con-  
trolled by the ADV input.  
• User-selectable burst counter supporting Intel®  
Pentium interleaved or linear burst sequences  
• Separate processor and controller address strobes  
• Synchronous self-timed writes  
Byte write operations are qualified with the two Byte Write Se-  
lect (BW  
) inputs. A Global Write Enable (GW) overrides the  
[0:1]  
• Asynchronous output enable  
byte write inputs and writes data to both bytes. All writes are  
conducted with on-chip synchronous self-timed write circuitry.  
• JEDEC-standard 100-pin TQFP pinout  
• “ZZ” Sleep Mode option and Stop Clock option  
Three synchronous chip selects (CE , CE , CE ) and an asyn-

chronous output enable (OE) provide for easy bank selection  
and output three-state control. In order to provide proper data  
during depth expansion, OE is masked during the first clock of  
a read cycle when emerging from a deselected state.
