CY7C199N

32 K × 8 Static RAM

K × 8 Static RAM

Features

Functional Description

■ High speed

❐ 15 ns

The CY7C199N is a high-performance CMOS static RAM

organized as 32,768 words by 8 bits. Easy memory expansion is

provided by an active LOW Chip Enable (CE) and active LOW

Output Enable (OE) and three-state drivers. This device has an

automatic power-down feature, reducing the power consumption

by 81% when deselected. The CY7C199NN is in the standard

300-mil-wide DIP, SOJ, and LCC packages.

■ Fast t_DOE

■ CMOS for optimum speed/power

■ Low active power

❐ 550 mW (max, 15 ns “L” version)

An active LOW Write Enable signal (WE) controls the

writing/reading operation of the memory. When CE and WE

inputs are both LOW, data on the eight data input/output pins

(I/O₀through I/O₇) is written into the memory location addressed

by the address present on the address pins (A₀through A₁₄).

Reading the device is accomplished by selecting the device and

enabling the outputs, CE and OE active LOW, while WE remains

inactive or HIGH. Under these conditions, the contents of the

location addressed by the information on address pins are

present on the eight data input/output pins.

■ Low standby power

❐ 0.275 mW (max, “L” version)

■ 2 V data retention (“L” version only)

■ Easy memory expansion with CE and OE features

■ TTL-compatible inputs and outputs

■ Automatic power-down when deselected

The input/output pins remain in a high-impedance state unless

the chip is selected, outputs are enabled, and Write Enable (WE)

is HIGH. A die coat is used to improve alpha immunity.
