CY7C1386DV25, CY7C1386FV25  
CY7C1387DV25, CY7C1387FV25  
18-Mbit (512K x 36/1M x 18) Pipelined DCD Sync SRAM  
Features  
Functional Description [1]  
• Supports bus operation up to 250 MHz  
The  
CY7C1386DV25/CY7C1387DV25/CY7C1386FV25/  
CY7C1387FV25 SRAM integrates 512K x 36 and 1M x 18  
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 [2]), 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.  
• Available speed grades are 250, 200, and 167 MHz  
• Registered inputs and outputs for pipelined operation  
• Optimal for performance (Double-Cycle deselect)  
• Depth expansion without wait state  
• 2.5V + 5% power supply (VDD  
)
• Fast clock-to-output times, 2.6 ns (for 250 MHz device)  
• Provides high-performance 3-1-1-1 access rate  
• User selectable burst counter supporting Intel® Pentium®  
interleaved or linear burst sequences  
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).  
• Separate processor and controller address strobes  
• Synchronous self timed writes  
• Asynchronous output enable  
• CY7C1386DV25/CY7C1387DV25 available in  
JEDEC-standard Pb-free 100-pin TQFP, Pb-free and non  
Pb-free 165-ball FBGA package.  
CY7C1386FV25/CY7C1387FV25 available in Pb-free and  
non Pb-free 119-ball BGA package  
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 6 and Truth Table [4,  
5, 6, 7, 8, 9]  
on page 9 for further details). Write cycles can be  
• IEEE 1149.1 JTAG-Compatible Boundary Scan  
• ZZ sleep mode option  
one to four bytes wide as controlled by the byte write control  
inputs. GW  
This  
causes all bytes to be written.  
active  
LOW  
device incorporates an additional pipelined enable register  
which delays turning off the output buffers an additional cycle  
when a deselect is executed.This feature allows depth  
expansion without penalizing system performance.  
The  
CY7C1386DV25/CY7C1387DV25/CY7C1386FV25/  
CY7C1387FV25 operates from a +2.5V power supply. All  
inputs  
and  
outputs  
are  
JEDEC-standard  
and  
JESD8-5-compatible.
