CY7C1480V33  
CY7C1482V33  
CY7C1486V33  
PRELIMINARY  
72-Mbit (2M x 36/4M x 18/1M x 72) Pipelined  
Sync SRAM  
Features  
Functional Description[1]  
• Supports bus operation up to 250 MHz  
• Available speed grades are 250, 200,167 MHz  
• Registered inputs and outputs for pipelined operation  
• 3.3V core power supply  
The CY7C1480V33/CY7C1482V33/CY7C1486V33 SRAM  
integrates 2,097,152 x 36/4,194,304 x 18,1,048,576 × 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 / 3.3V I/O operation  
• Fast clock-to-output times  
— 3.0 ns (for 250-MHz device)  
— 3.0 ns (for 200-MHz device)  
— 3.4 ns (for 167-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) are 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 Descriptions and Truth Table for further  
details). Write cycles can be one to two or four bytes wide as  
controlled by the byte write control inputs. GW when active  
• Asynchronous output enable  
• Single Cycle Chip Deselect  
• CY7C1480V33 and CY7C1482V33 offered in  
JEDEC-standardlead-free100-pinTQFP, 165-BallfBGA  
packages. CY7C1486V33 available in 209-Ball BGA  
packages  
causes all bytes to be written.  
LOW  
The CY7C1480V33/CY7C1482V33/CY7C1486V33 operates  
from a +3.3V core power supply while all outputs may operate  
with either a +2.5 or +3.3V supply. All inputs and outputs are  
JEDEC-standard JESD8-5-compatible.  
• IEEE 1149.1 JTAG-Compatible Boundary Scan  
• “ZZ” Sleep Mode Option
