1-Mbit (128K x 8) Static RAM
Features
Functional Description[1]
• Temperature Ranges
The CY62128B is a high-performance CMOS static RAM
organized as 131,072 words by 8 bits. Easy memory
—Commercial: 0°C to 70°C
— Industrial: –40°C to 85°C
expansion is provided by an active LOW Chip Enable (CE ),
1
an active HIGH Chip Enable (CE ), an active LOW Output
2
Enable (OE), and three-state drivers. This device has an
automatic power-down feature that reduces power
consumption by more than 75% when deselected.
— Automotive: –40°C to 125°C
• 4.5V–5.5V operation
• CMOS for optimum speed/power
• Low active power
(70 ns, LL version, Commercial, Industrial)
Writing to the device is accomplished by taking Chip Enable
One (CE ) and Write Enable (WE) inputs LOW and Chip
1
Enable Two (CE ) input HIGH. Data on the eight I/O pins (I/O
2
0
— 82.5 mW (max.) (15 mA)
through I/O ) is then written into the location specified on the
7
• Low standby power
(70 ns, LL version, Commercial, Industrial)
address pins (A through A ).
0
16
Reading from the device is accomplished by taking Chip
Enable One (CE ) and Output Enable (OE) LOW while forcing
— 110 µW (max.) (15 µA)
1
• Automatic power-down when deselected
• TTL-compatible inputs and outputs
Write Enable (WE) and Chip Enable Two (CE ) HIGH. Under
these conditions, the contents of the memory location
specified by the address pins will appear on the I/O pins.
2
• Easy memory expansion with CE , CE , and OE options

The eight input/output pins (I/O through I/O ) are placed in a
0
7
high-impedance state when the device is deselected (CE
1
HIGH or CE LOW), the outputs are disabled (OE HIGH), or
2
during a write operation (CE LOW, CE HIGH, and WE LOW).

The CY62128B is available in a standard 450-mil-wide SOIC,
32-pin TSOP type I and STSOP packages.
