DESCRIPTION  
The P4C1256 device provides asynchronous operation  
with matching access and cycle times. Memory loca-  
tions are specified on address pins A0 to A14. Reading  
is accomplished by device selection (CE and output  
enabling (OE) while write enable (WE) remains HIGH.  
By presenting the address under these conditions, the  
data in the addressed memory location is presented on  
the data input/output pins. The input/output pins stay  
in the HIGH Z state when either CE or OE is HIGH or  
WE is LOW.  
The P4C1256 is a 262,144-bit high-speed CMOS  
static RAM organized as 32Kx8. The CMOS memory  
requires no clocks or refreshing, and has equal access  
and cycle times. Inputs are fully TTL-compatible. The  
RAM operates from a single 5V±10% tolerance power  
supply.  
Access times as fast as 12 nanoseconds permit greatly  
enhanced system operating speeds. CMOS is utilized  
to reduce power consumption to a low level. The  
P4C1256 is a member of a family of PACE RAM™ prod-  
ucts offering fast access times.  
Package options for the P4C1256 include 28-pin 300  
mil DIP, SOJ and TSOP packages. For military tempera-  
ture range, Ceramic DIP and LCC packages are avail-  
able.
