W27E257  
32K ´ 8 ELECTRICALLY ERASABLE EPROM  
GENERAL DESCRIPTION  
The W27E257 is a high-speed, low-power Electrically Erasable and Programmable Read Only  
Memory organized as 32768 ´ 8 bits that operates on a single 5 volt power supply. The W27E257  
provides an electrical chip erase function. This part was the same EPROM Writer's utilities as the  
W27E256.  
FEATURES  
· High speed access time:  
100/120/150 nS (max.)  
· +14V erase/+12V programming voltage  
· Fully static operation  
· Read operating current: 15 mA (typ.)  
· All inputs and outputs directly TTL/CMOS  
compatible  
· Erase/Programming operating current  
1 mA (typ.)  
· Three-state outputs  
· Available packages: 28-pin 600 mil DIP and  
32-pin PLCC  
· Standby current: 5 mA (typ.)  
· Single 5V power supply
