Functional Description
The CY7C1329H SRAM integrates 64 K × 32 SRAM cells with
advanced synchronous peripheral circuitry and a two-bit counter
for internal burst operation. 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 (CE1), depth-expansion
Chip Enables (CE2 and CE3), Burst Control inputs (ADSC,
ADSP, and ADV), Write Enables (BW[A:D] and BWE), and Global
Write (GW). Asynchronous inputs include the Output Enable
(OE) and the ZZ pin.
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).
Address, data inputs, and write controls are registered on-chip
to initiate a self-timed Write cycle. This part supports Byte Write
operations (see Pin Definitions on page 4 and Truth Table on
page 7 for further details). Write cycles can be one to four bytes
wide as controlled by the Byte Write control inputs. GW when
active LOW causes all bytes to be written.
The CY7C1329H operates from a +3.3 V core power supply
while all outputs operate with either a +2.5 V or +3.3 V supply.
All inputs and outputs are JEDEC-standard
JESD8-5-compatible.
