CY7C199CN

256K (32K x 8) Static RAM

Features

General Description ^[1]

• Fast access time: 12 ns, 15 ns, 20 ns, and 25 ns

• Wide voltage range: 5.0V ± 10% (4.5V to 5.5V)

• CMOS for optimum speed and power

• TTL-compatible inputs and outputs

• 2.0V data retention

The CY7C199CN is a high performance CMOS Asynchronous

SRAM organized as 32K by 8 bits that supports an

asynchronous memory interface. The device features an

automatic power down feature that reduces power

consumption when deselected.

See the “Truth Table” on page 3 in this data sheet for a

complete description of read and write modes.

• Low CMOS standby power

• Automated power down when deselected

The CY7C199CN is available in Pb-free 28-pin TSOP I, 28-pin

Molded SOJ and 28-pin DIP package(s).

• Available in Pb-free 28-pin TSOP I, 28-pin Molded SOJ and

28-pin DIP packages
