CY7C1338  
128K x 32 Synchronous-Flow-Through 3.3V Cache RAM  
Features  
Functional Description  
• Supports117-MHzmicroprocessorcachesystems with  
zero wait states  
• 128K by 32 common I/O  
• Fast clock-to-output times  
— 7.5 ns (117-MHz version)  
The CY7C1338 is a 3.3V, 128K by 32 synchronous cache  
RAM designed to interface with high-speed microprocessors  
with minimum glue logic. Maximum access delay from clock  
rise is 7.5 ns (117-MHz version). A 2-bit on-chip counter cap-  
tures the first address in a burst and increments the address  
automatically for the rest of the burst access.  
• Two-bit wraparound counter supporting either inter-  
leaved or linear burst sequence  
• Separate processorand controller address strobes pro-  
vide direct interface with the processor and external  
cache controller  
• Synchronous self-timed write  
• Asynchronous output enable  
• 3.3V I/Os  
• JEDEC-standard pinout  
• 100-pin TQFP packaging  
• ZZ “sleep” mode  
The CY7C1338 allows both interleaved and linear burst se-  
quences, selected by the MODE input pin. A HIGH selects an  
interleaved burst sequence, while a LOW selects a linear burst  
sequence. Burst accesses can be initiated with the Processor  
Address Strobe (ADSP) or the cache Controller Address  
Strobe (ADSC) inputs. Address advancement is controlled by  
the address advancement (ADV) input.  
A synchronous self-timed write mechanism is provided to sim-  
plify the write interface. A synchronous chip enable input and  
an asynchronous output enable input provide easy control for  
bank selection and output three-state control.
