Synchronous Dual-Port RAM

Functional Description

Features

• True dual-ported memory cells that allow simultaneous

The FLEx36 family includes 1M, 2M, 4M and 9M pipelined,

synchronous, true dual-port static RAMs that are high-speed,

low-power 3.3V CMOS. Two ports are provided, permitting

independent, simultaneous access to any location in memory.

The result of writing to the same location by more than one port

at the same time is undefined. Registers on control, address,

and data lines allow for minimal set-up and hold time.

During a Read operation, data is registered for decreased

cycle time. Each port contains a burst counter on the input

address register. After externally loading the counter with the

initial address, the counter will increment the address inter-

nally (more details to follow). The internal Write pulse width is

independent of the duration of the R/W input signal. The

internal Write pulse is self-timed to allow the shortest possible

cycle times.

access of the same memory location

• Synchronous pipelined operation

• Organization of 1-Mbit, 2-Mbit, 4-Mbit and 9-Mbit

devices

• Pipelined output mode allows fast operation

• 0.18-micron CMOS for optimum speed and power

• High-speed clock to data access

• 3.3V low power

—Active as low as 225 mA (typ)

— Standby as low as 55 mA (typ)

• Mailbox function for message passing

• Global master reset

• Separate byte enables on both ports

• Commercial and industrial temperature ranges

• IEEE 1149.1-compatible JTAG boundary scan

• 172-ball FBGA (1 mm pitch) (15 mm × 15 mm)

• 176-pin TQFP (24 mm × 24 mm × 1.4 mm)

• Counter wrap around control

A HIGH on CE0 or LOW on CE1 for one clock cycle will power

down the internal circuitry to reduce the static power

consumption. One cycle with chip enables asserted is required

to reactivate the outputs.

Additional features include: readback of burst-counter internal

address value on address lines, counter-mask registers to

control the counter wrap-around, counter interrupt (CNTINT)

flags, readback of mask register value on address lines,

retransmit functionality, interrupt flags for message passing,

JTAG for boundary scan, and asynchronous Master Reset

(MRST).

— Internal mask register controls counter wrap-around

— Counter-interrupt flags to indicate wrap-around

— Memory block retransmit operation

• Counter readback on address lines

• Mask register readback on address lines

The CY7C0853 device in this family has limited features.

Please see See “Address Counter and Mask Register

Operations^[10]” on page 8. for details.

• Dual Chip Enables on both ports for easy depth
