Functional Description
The Cypress Synchronous Burst SRAM family employs
high-speed, low-power CMOS designs using advanced
triple-layer polysilicon, double-layer metal technology. Each
memory cell consists of four transistors and two high-valued
resistors.
The CY7C1360A and CY7C1362A SRAMs integrate 262,144
×
36 and 524,288
×
18 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 (CE), depth-expansion
Chip Enables (CE
2
and CE
3
), burst control inputs (ADSC,
ADSP, and ADV), Write Enables (BWa, BWb, BWc, BWd, and
BWE), and global Write (GW). However, the CE
3
chip enable
input is only available for the TA package version.
Asynchronous inputs include the Output Enable (OE) and
burst mode control (MODE). The data outputs (Q), enabled by
OE, are also asynchronous.
Addresses and chip enables are registered with either
Address Status Processor (ADSP) or Address Status
Controller (ADSC) input pins. Subsequent burst addresses
can be internally generated as controlled by the Burst Advance
Pin (ADV).
Address, data inputs, and Write controls are registered on-chip
to initiate self-timed Write cycle. Write cycles can be one to
four bytes wide as controlled by the Write control inputs.
Individual byte Write allows individual byte to be written. BWa
controls DQa. BWb controls DQb. BWc controls DQc. BWd
controls DQd. BWa, BWb, BWc, and BWd can be active only
with BWE being LOW. GW being LOW causes all bytes to be
written. The x18 version only has 18 data inputs/outputs (DQa
and DQb) along with BWa and BWb (no BWc, BWd, DQc, and
DQd).
For the B and T package versions, four pins are used to
implement JTAG test capabilities: Test Mode Select (TMS),
Test Data-In (TDI), Test Clock (TCK), and Test Data-Out
(TDO). The JTAG circuitry is used to serially shift data to and
from the device. JTAG inputs use LVTTL/LVCMOS levels to
shift data during this testing mode of operation. The TA
package version does not offer the JTAG capability.
The CY7C1360A and CY7C1362A operate from a +3.3V
power supply. All inputs and outputs are LVTTL-compatible.
