Features  
Functional Description[1]  
• Supports 133 MHz bus operations  
• 2M x 36/4M x 18/1M x 72 common IO  
The CY7C1481V25/CY7C1483V25/CY7C1487V25 is a 2.5V,  
2M x 36/4M x 18/1M x 72 Synchronous Flow-through SRAM  
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  
• 2.5V core power supply (VDD  
)
• 2.5V or 1.8V IO supply (VDDQ  
• Fast clock-to-output time  
— 6.5 ns (133-MHz version)  
)
• Provide high-performance 2-1-1-1 access rate  
• User selectable burst counter supporting Intel® Pentium®  
interleaved or linear burst sequences  
Control inputs (ADSC, ADSP, and ADV), Write Enables (BW  
and BWE), and Global Write (GW). Asynchronous inputs  
,
x
• Separate processor and controller address strobes  
• Synchronous self timed write  
include the Output Enable (OE) and the ZZ pin.  
• Asynchronous output enable  
The CY7C1481V25/CY7C1483V25/CY7C1487V25 enables  
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  
inputs. Address advancement is controlled by the Address  
Advancement (ADV) input.  
• CY7C1481V25, CY7C1483V25 available in  
JEDEC-standard Pb-free 100-pin TQFP, Pb-free and  
non-Pb-free 165-ball FBGA package. CY7C1487V25  
available in Pb-free and non-Pb-free 209-ball FBGA  
package  
(ADSC)  
• IEEE 1149.1 JTAG-Compatible Boundary Scan  
• “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 CY7C1481V25/CY7C1483V25/CY7C1487V25 operates  
from a +2.5V core power supply while all outputs may operate  
with either a +2.5 or +1.8V supply. All inputs and outputs are  
JEDEC-standard JESD8-5-compatible.
