CY7C199 • High speed 10 ns • Fast tDOE • CMOS for optimum speed/power • Low active power 467 mW max, 12 ns “L” version • Low standby power mW max, “L” version • 2V data retention “L” version only • Easy memory expansion with CE and OE features • TTL-compatible inputs and outputs • Automatic power-down when deselected Functional Description The CY7C199 is a high-performance CMOS static RAM organized as 32,768 words by 8 bits. Easy memory expansion is 32K x 8 Static RAM 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 CY7C199 is in the standard 300-mil-wide DIP, SOJ, and LCC packages. 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/O0 through I/O7 is written into the memory location addressed by the address present on the address pins A0 through 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. 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.

Functional Description

The CY7C199 is a high-performance CMOS static RAM organized as 32,768 words by 8 bits. Easy memory expansion is
32K x 8 Static RAM
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 CY7C199 is in the standard 300-mil-wide DIP, SOJ, and LCC packages.

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/O0 through I/O7 is written into the memory location addressed by the address present on the address pins A0 through 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.

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.
