com W39V040A 512K × 8 CMOS FLASH MEMORY WITH LPC INTERFACE 1.
GENERAL DESCRIPTION The W39V040A is a 4-megabit, 3.
3-volt only CMOS flash memory organized as 512K × 8 bits.
For flexible erase capability, the 4Mbits of data are divided into 8 uniform sectors of 64 Kbytes, which are composed of 16 smaller even pages with 4 Kbytes.
The device can be programmed and erased in-system with a standard 3.
3V power supply.
A 12-volt VPP is not required.
The unique cell architecture of the W39V040A results in fast program/erase operations with extremely low current consumption.
This device can operate at two modes, Programmer bus interface mode and LPC bus interface mode.
As in the Progra...
