Functional Description
[1]
The CY7C1381D/CY7C1383D is a 3.3V, 512K x 36 and 1 Mbit
x 18 Synchronous Flow-through SRAMs, respectively
designed to interface with high-speed microprocessors with
minimum glue logic. Maximum access delay from clock rise is
6.5 ns (133-MHz version). A 2-bit on-chip counter captures the
first address in a burst and increments the address automati-
cally for the rest of the burst access. 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
(CE
), depth-expansion Chip Enables (CE
2
and
CE
3[2]
), Burst
Control inputs (ADSC, ADSP, and ADV), Write Enables (BW
x
,
and BWE), and Global Write (GW). Asynchronous inputs
include the Output Enable (OE) and the ZZ pin.
The CY7C1381D/CY7C1383D allows either interleaved or
linear burst sequences, selected by the MODE input pin. A
HIGH selects an interleaved burst sequence, while a LOW
selects a linear burst sequence. Burst accesses can be
initiated with the Processor Address Strobe (ADSP) or the
cache Controller Address Strobe (ADSC) inputs. Address
advancement is controlled by the Address Advancement
(ADV) input.
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).
The CY7C1381D/CY7C1383D operates from a +3.3V core
power supply while all outputs may operate with either a +2.5
or +3.3V supply. All inputs and outputs are JEDEC-standard
JESD8-5-compatible.
