Cypress CY7C1021BN-15VI 1-mbit (64k x 16) static ram Datasheet

CY7C1021BN
CY7C10211BN
1-Mbit (64K x 16) Static RAM
Features
Writing to the device is accomplished by taking Chip Enable
(CE) and Write Enable (WE) inputs LOW. If Byte Low Enable
(BLE) is LOW, then data from I/O pins (I/O1 through I/O8), is
written into the location specified on the address pins (A0
through A15). If Byte High Enable (BHE) is LOW, then data
from I/O pins (I/O9 through I/O16) is written into the location
specified on the address pins (A0 through A15).
• Temperature Ranges
— Commercial: 0°C to 70°C
— Industrial: –40°C to 85°C
— Automotive-A: –40°C to 85°C
Reading from the device is accomplished by taking Chip
Enable (CE) and Output Enable (OE) LOW while forcing the
Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW,
then data from the memory location specified by the address
pins will appear on I/O1 to I/O8. If Byte High Enable (BHE) is
LOW, then data from memory will appear on I/O9 to I/O16. See
the truth table at the back of this data sheet for a complete
description of read and write modes.
— Automotive-E: –40°C to 125°C
• High speed
— tAA = 10 ns (Commercial)
— tAA = 15 ns (Automotive)
• CMOS for optimum speed/power
• Low active power
— 825 mW (max.)
• Automatic power-down when deselected
• Independent control of upper and lower bits
• Available in Pb free and non Pb free 44-pin TSOP II and
44-pin 400-mil-wide SOJ
Functional Description[1]
The CY7C1021BN/CY7C10211BN is a high-performance
CMOS static RAM organized as 65,536 words by 16 bits. This
device has an automatic power-down feature that significantly
reduces power consumption when deselected.
The input/output pins (I/O1 through I/O16) are placed in a
high-impedance state when the device is deselected (CE
HIGH), the outputs are disabled (OE HIGH), the BHE and BLE
are disabled (BHE, BLE HIGH), or during a write operation (CE
LOW, and WE LOW).
The CY7C1021BN/CY7C10211BN is available in standard
44-pin TSOP Type II and 44-pin 400-mil-wide SOJ packages.
Customers should use part number CY7C10211BN when
ordering parts with 10 ns tAA, and CY7C1021BN when
ordering 12 ns and 15 ns tAA.

IOL/IOH and 30-pF load capacitance.
6. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device.
7. tHZOE, tHZBE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ±500 mV from steady-state
voltage.

Notes:
8. The internal write time of the memory is defined by the overlap of CE LOW, WE LOW and BHE / BLE LOW. CE, WE and BHE / BLE must be LOW to initiate a
write, and the transition of these signals can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that
terminates the write.
9. Device is continuously selected. OE, CE, BHE and/or BHE = VIL.
10. WE is HIGH for read cycle.
