DESCRIPTION
The P4C1299 and P4C1299L are a 262,144-bit ultra high-
speed static RAM organized as 64K x 4.The CMOS memory
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. With battery backup (P4C1299LOnly), data integrity
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.
