CY7C1217H  
1-Mbit (32K x 36) Flow-Through Sync SRAM  
Features  
Functional Description[1]  
The CY7C1217H is a 32K x 36 synchronous cache RAM  
designed to interface with high-speed microprocessors with  
minimum glue logic. Maximum access delay from clock rise is  
6.5 ns (133-MHz version). A 2-bit on-chip counter captures the  
first address in a burst and increments the address automati-  
cally for the rest of the burst access. All synchronous inputs  
are gated by registers controlled by a positive-edge-triggered  
Clock Input (CLK). The synchronous inputs include all  
addresses, all data inputs, address-pipelining Chip Enable  
(CE1), depth-expansion Chip Enables (CE2 and CE3), Burst  
Control inputs (ADSC, ADSP, and ADV), Write Enables  
(BW[A:D], and BWE), and Global Write (GW). Asynchronous  
inputs include the Output Enable (OE) and the ZZ pin.  
• 32K x 36 common I/O  
• 3.3V core power supply (VDD  
)
• 2.5V/3.3V I/O power supply (VDDQ  
)
• Fast clock-to-output times  
— 6.5 ns (for 133-MHz version)  
• Provide high-performance 2-1-1-1 access rate  
• User-selectable burst counter supporting Intel®  
Pentium® interleaved or linear burst sequences  
• Separate processor and controller address strobes  
• Synchronous self-timed write  
The CY7C1217H allows either interleaved or linear burst  
sequences, 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.  
• Asynchronous output enable  
• Available in JEDEC-standard lead-free 100-Pin TQFP  
package  
• “ZZ” Sleep Mode option  
Addresses and chip enables are registered at rising edge of  
clock when either Address Strobe Processor (ADSP) or  
Address Strobe Controller (ADSC) are active. Subsequent  
burst addresses can be internally generated as controlled by  
the Advance pin (ADV).  
The CY7C1217H operates from a +3.3V core power supply  
while all outputs may operate either with a +2.5V or +3.3V  
supply. All inputs and outputs are JEDEC-standard  
JESD8-5-compatible.
