DESCRIPTIOn

The P4C1299 and P4C1299L are a 262,144-bit ultra high-

speedstaticRAMorganizedas64Kx4.TheCMOSmemory

requires no clock or refreshing and has equal access and

cycle times. Inputs and outputs are fully TTL-compatible.

The RAM operates from a single 5V±10% tolerance power

supply.Withbatterybackup(P4C1299LOnly),dataintegrity

is maintained for supply voltages down to 2.0V. Current

drain is typically 10 µA from a 2.0V supply.

Access times as fast as 15 nanoseconds are available,

permitting greatly enhanced system speeds. CMOS is

utilized to reduce power consumption.

The P4C1299 and P4C1299L are available in a 28-pin

300 mil DIP or SOJ, as well as a 28-pin 350x550 mil LCC

package, providing excellent board level densities.
