Preliminary W27L010  
128K ´ 8 ELECTRICALLY ERASABLE EPROM  
GENERAL DESCRIPTION  
The W27L010 is a high speed, low power consumption Electrically Erasable and Programmable Read  
Only Memory organized as 131072 ´ 8 bits. It requires only one supply in the range of 3.0V to 3.6V in  
normal read mode. The W27L010 provides an electrical chip erase function.  
FEATURES  
· High speed access time:  
90/120 nS (max.)  
· +14V erase/+12V programming voltage  
· Fully static operation  
· Read operating current: 10 mA (max.)  
· All inputs and outputs directly TTL/CMOS  
· Erase/Programming operating current:  
compatible  
30 mA (max.)  
· Three-state outputs  
· Standby current: 20 mA (max.)  
· Available packages: 32-pin 600 mil DIP, 450  
· Low voltage power supply range, 3.0V to 3.6V  
mil SOP and PLCC
