CY7C1480BV25  
CY7C1482BV25, CY7C1486BV25  
72-Mbit (2M x 36/4M x 18/1M x 72)  
Pipelined Sync SRAM  
Features  
Functional Description  
Supports bus operation up to 250 MHz  
Available speed grades are 250, 200, and 167 MHz  
Registered inputs and outputs for pipelined operation  
2.5V core power supply  
The  
CY7C1480BV25/CY7C1482BV25/CY7C1486BV25[1]  
SRAM integrates 2M x 36/4M x 18/1M × 72 SRAM cells with  
advanced synchronous peripheral circuitry and a two-bit counter  
for internal burst operation. 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 (BWX, and BWE), and Global  
Write (GW). Asynchronous inputs include the Output Enable  
(OE) and the ZZ pin.  
2.5V IO operation  
Fast clock-to-output time  
3.0 ns (for 250 MHz device)  
Provide high performance 3-1-1-1 access rate  
Addresses and chip enables are registered at rising edge of  
clock when either Address Strobe Processor (ADSP) or Address  
Strobe Controller (ADSC) is active. Subsequent burst addresses  
can be internally generated as controlled by the Advance pin  
(ADV).  
User selectable burst counter supporting Intel® Pentium®  
interleaved or linear burst sequences  
Separate processor and controller address strobes  
Synchronous self timed writes  
Address, data inputs, and write controls are registered on-chip  
to initiate a self timed Write cycle. This part supports Byte Write  
operations (see “Pin Definitions” on page 7 and “Truth Table” on  
page 10 for further details). Write cycles can be one to two or four  
bytes wide, as controlled by the byte write control inputs. When  
it is active LOW, GW writes all bytes.  
Asynchronous output enable  
Single cycle chip deselect  
CY7C1480BV25, CY7C1482BV25 available in  
JEDEC-standard Pb-free 100-pin TQFP, Pb-free and  
non-Pb-free 165-ball FBGA package. CY7C1486BV25  
available in Pb-free and non-Pb-free 209-ball FBGA package
