Preliminary W27C520  
´ 8 ELECTRICALLY ERASABLE EPROM  
64K  
GENERAL DESCRIPTION  
The W27C520 is a high speed, low power Electrically Erasable and Programmable Read Only Memory  
organized as 65,536 ´ 8 bits. It includes latches for the lower 8 address lines to multiplex with the 8  
data lines. To cooperate with the MCU, this device could save the external TTL component, also cost  
and space. It requires only one supply in the range of 3.0V to 3.6V or 4.5V to 5.5V in normal read  
mode. The W27C520 provides an electrical chip erase function. It will be a great convenient when you  
need to change/update the contents in the device.  
FEATURES  
· High speed access time: 70/90 nS (max.)  
· Read operating current: 8/20 mA (max.)  
· Erase/Programming operating current  
· High Reliability CMOS Technology  
- 2K V ESD Protection  
- 200 mA Latchup Immunity  
· Fully static operation  
30 mA (max.)  
· All inputs and outputs directly LVTTL/CMOS  
compatible  
· Three-state outputs  
· Standby current: 20/100 mA (max.)  
· Unregulated battery power supply range,  
3.0V to 3.6V and 4.5V to 5.5V  
· Available packages: 20-pin TSSOP and 20-pin  
SOP  
· +13V erase and programming voltage
