GENERAL DESCRIPTION
The W49F102 is a 1-megabit, 5-volt only CMOS flash memory organized as 64K
can be programmed and erased in-system with a standard 5V power supply. A 12-volt V
required. The unique cell architecture of the W49F102 results in fast program/erase operations with
extremely low current consumption (compared to other comparable 5-volt flash memory products). The
device can also be programmed and erased using standard EPROM programmers.

... FUNCTIONAL DESCRIPTION Read Mode The read operation of the W49F102 is controlled by CE and OE, both of which have to be low for the host to obtain data from the outputs used for device selection. When CE is high, the chip is de-selected and only standby power will be consumed the output control and is used to gate data from the output pins ...

Hardware Data Protection The integrity of the data stored in the W49F102 is also hardware protected in the following ways: (1) Noise/Glitch Protection pulse of less than duration will not initiate a write cycle. (2) V Power Up/Down Detection: The programming operation is inhibited when ...
