CY7C1360B

CY7C1362B

PRELIMINARY

256K x 36/512K x 18 Pipelined SRAM

All synchronous inputs pass through input registers controlled

by the rising edge of the clock. All data outputs pass through

output registers controlled by the rising edge of the clock.

Maximum access delay from the clock rise is 2.6 ns (250 MHz

Features

• Supports bus operation up to 250 MHz

— Available speed grades are 250, 200, and 166 MHz

device).

• Fully registered inputs and outputs for pipelined

operation

• Single 3.3V power supply

• Supports 3.3V and 2.5V I/Os

• Fast clock-to-output times

— 2.6ns (for 250-MHz device)

The CY7C1360B and CY7C1362B support either the inter-

leaved burst sequence used by the Intel Pentium processor or

a linear burst sequence used by processors such as the

PowerPC™. The burst sequence is selected through the

MODE pin (Pin 31 and ball R3 for the TQFP and BGA

packages, respectively.) Accesses can be initiated by

asserting either the Processor Address Strobe (ADSP) or the

Controller Address Strobe (ADSC) at clock rise. Address

advancement through the burst sequence is controlled by the

ADV input. A 2-bit on-chip wraparound burst counter captures

the first address in a burst sequence and automatically incre-

ments the address for the rest of the burst access.

— 3.0ns (for 200-MHz device)

— 3.5 ns (for 166-MHz device)

• 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

• Single Cycle Chip Deselect

• Available as a 100-pin TQFP, 119-Ball BGA, 165-Ball

fBGA

Byte write operations are qualified with the Byte Write Select

(BW_a,b,c,dfor 1360B and BW_a,bfor 1362B) inputs. A Global

Write Enable (GW) overrides all byte write inputs and writes

data to all four bytes. All writes are conducted with on-chip

synchronous self-timed write circuitry.

Three synchronous Chip Selects (CE₁, CE₂, CE₃) and an

asynchronous Output Enable (OE) provide for easy bank

selection and output three-state control. In order to provide

proper data during depth expansion, OE is masked during the

first clock of a read cycle when emerging from a deselected

state.

• TQFP Available with 3-Chip Enable and 2-Chip Enable

• IEEE 1149.1 JTAG-Compatible Boundary Scan

• “ZZ” Sleep Mode option and Stop Clock option

Functional Description

The CY7C1360B and CY7C1362B are 3.3V, 256K x 36 and

512K x 18 synchronous-pipelined cache SRAM, respectively.
