PRELIMINARY

FullFlex™ Synchronous

DDR Dual-Port SRAM

— Selectable LVTTL (3.3V), Extended HSTL

(1.4V–1.9V), 1.8V LVCMOS, or 2.5V LVCMOS I/O on

each port

Features

• True dual-ported memory allows simultaneous access

to the shared array from each port

— Burst counters for sequential memory access

— Mailbox with interrupt flags for message passing

— Dual Chip Enables for easy depth expansion

• Synchronous pipelined operation with selectable

Double Data Rate (DDR) or Single Data Rate (SDR)

operation on each port

— DDR SRAM interface (data transferred at 400 Mbps)

Functional Description

@ 200 MHz

The FullFlex Dual-Port SRAM families consist of 4-Mbit,

9-Mbit, 18-Mbit, and 36-Mbit synchronous, true dual-port static

RAMs that are high-speed, low-power 1.8V/1.5V CMOS. Two

ports are provided, allowing the array to be accessed simulta-

neously. Simultaneous access to a location triggers determin-

istic access control. For FullFlex72, these ports can operate

independently in DDR mode with 36-bit bus widths or in SDR

mode with 72-bit bus widths. For FullFlex36 and FullFlex18,

the ports operate in DDR mode only. Each port can be

independently configured for two pipeline stages for SDR

mode or 2.5 stages in DDR mode. Each port can also be

configured to operate in pipeline or flow-through mode in SDR

mode.

Advanced features include built-in deterministic access

control to manage address collisions during simultaneous

access to the same memory location, variable impedance

Matching (VIM) to improve data transmission by matching the

output driver impedance to the line impedance, and echo

clocks to improve data transfer.

— SDR interface at 250 MHz

— Up to 36-Gb/s bandwidth (250 MHz * 72 bit * 2 ports)

• Selectable pipeline or flow-through mode

• Selectable 1.5V or 1.8V core power supply

• Commercial and Industrial temperature ranges

• IEEE 1149.1 JTAG boundary scan

• Available in 484-ball PBGA Packages and 256-ball

FBGA Packages

• FullFlex72 family

— 36 Mbit: 512K x 72 (CYDD36S72V18)

— 18 Mbit: 256K x 72 (CYDD18S72V18)

— 9 Mbit: 128K x 72 (CYDD09S72V18)

— 4 Mbit: 64K x 72 (CYDD04S72V18)

• FullFlex36 family

— 36 Mbit: 512K x 72 (CYDD36S36V18)

— 18 Mbit: 256K x 72 (CYDD18S36V18)

— 9 Mbit: 128K x 72 (CYDD09S36V18)

— 4 Mbit: 64K x 72 (CYDD04S36V18)

• FullFlex18 family

— 36 Mbit: 1M x 36 (CYDD36S18V18)

— 18 Mbit: 512K x 36 (CYDD18S18V18)

— 9 Mbit: 256K x 36 (CYDD09S18V18)

— 4 Mbit: 128K x 36 (CYDD04S18V18)

To reduce the static power consumption, chip enables can be

used to power down the internal circuitry. The number of

cycles of latency before a change in CE0 or CE1 will enable

or disable the databus matches the number of cycles of read

latency selected for the device. In order for a valid write or read

to occur, both chip enable inputs on a port must be active.

Each port contains an optional burst counter on the input

address register. After externally loading the counter with the

initial address, the counter will increment the address inter-

nally.

Additional features of this device include a mask register and

mirror register to control counter increments and

• Built-in deterministic access control to manage

wrap-around, counter-interrupt (CNTINT) flags to notify that

the counter will reach the maximum value on the next clock

cycle, readback of the burst-counter internal address, mask

retransmit functionality, mailbox interrupt flags for message

passing, JTAG for boundary scan, and asynchronous Master

Reset (MRST). The logic block diagram in Figure 1 displays

these features.

address collisions

— Deterministic flag output upon collision detection

— Collision detection on back-to-back clock cycles

— First Busy Address readback

• Advanced features for improved high-speed data

transfer and flexibility

— Variable impedance Matching (VIM)

— Echo clocks

The FullFlex72 DDR family of devices is offered in a 484-ball

plastic BGA package. The FullFlex36 and FullFlex18 DDR

only families of devices are offered in a 256-ball fine pitch BGA

package.
