W27L02  
256K × 8 ELECTRICALLY ERASABLE EPROM  
1. GENERAL DESCRIPTION  
The W27L02 is a high speed, low power consumption Electrically Erasable and Programmable Read  
Only Memory organized as 262,144 x 8 bits. It requires only one supply in the range of 3.3V ±10% in  
normal read mode. The W27L02 provides an electrical chip erase function.  
2. FEATURES  
+12V erase/programming voltage  
Fully static operation  
Wide range for power supply voltage:  
3.3V ±10%  
High speed access time: 70/90 nS (max.)  
Read operating current: 15 mA (max.)  
All inputs and outputs directly TTL/CMOS  
compatible  
Three-state outputs  
Erase/Programming operating current:  
30 mA (max.)  
Available packages: 32-lead PLCC and 32-lead  
STSOP  
Standby current: 20 µA (max.)
