8 ELECTRICALLY ERASABLE EPROM
GENERAL DESCRIPTION
The W27E520 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 4.5V to 5.5V in normal
read mode. The W27E520 provides an electrical chip erase function. It will be a great convenient
when you need to change/update the contents in the device.
