CY7C1387D

18-Mbit (512K x 36/1 Mbit x 18) Pipelined

DCD Sync SRAM

Features

Functional Description^[1]

• Supports bus operation up to 250 MHz

The CY7C1386D/CY7C1387D SRAM integrates 524,288 x 36

and 1,048,576 x 18 SRAM cells with advanced synchronous

• 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

• 3.3V –5% and +10% core power supply (V_DD

• 2.5V/3.3V I/O operation

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 (CE₂and CE₃^[2]), Burst Control inputs (ADSC, ADSP,

)

ADV), Write Enables (

, and BWE), and Global Write

and

BW_X

(GW). Asynchronous inputs include the Output Enable (OE)

• Fast clock-to-output times

and the ZZ pin.

— 2.6 ns (for 250-MHz device)

— 3.0 ns (for 200-MHz device)

— 3.4 ns (for 167-MHz device)

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).

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 four bytes wide as

controlled by the byte write control inputs. GW active LOW

causes all bytes to be written. This 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 penal-

izing system performance.

• Provide high-performance 3-1-1-1 access rate

• User-selectable burst counter supporting Intel^

Pentium^interleaved or linear burst sequences

• Separate processor and controller address strobes

• Synchronous self-timed writes

• Asynchronous output enable

• Offered in JEDEC-standard lead-free 100-pin TQFP,

119-ball BGA and 165-Ball fBGA packages

• IEEE 1149.1 JTAG-Compatible Boundary Scan

• “ZZ” Sleep Mode Option

The CY7C1386D/CY7C1387D operates from a +3.3V core

power supply while all outputs operate with a +3.3V or a +2.5V

supply. All inputs and outputs are JEDEC-standard

JESD8-5-compatible.
