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

IEEE 1149.1 JTAG-Compatible Boundary Scan

“ZZ” Sleep Mode option and Stop Clock option

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

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.

Byte write operations are qualified with the Byte Write Select

(BW

a,b,c,d

for 1360B and BW

a,b

for 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 (CE

, CE

) 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.

Functional Description

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

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