DESCRIPTION

Decoder

The Microchip Technology Inc. 28LV64A is a CMOS 64K non-vol-

atile electrically Erasable PROM organized as 8K words by 8 bits.

The 28LV64A is accessed like a static RAM for the read or write

cycles without the need of external components. During a “byte

write”, the address and data are latched internally, freeing the

microprocessor address and data bus for other operations. Fol-

lowing the initiation of write cycle, the device will go to a busy state

and automatically clear and write the latched data using an inter-

nal control timer. To determine when the write cycle is complete,

the user has a choice of monitoring the Ready/Busy output or

using Data polling. The Ready/Busy pin is an open drain output,

which allows easy configuration in ‘wired-or’ systems. Alterna-

tively, Data polling allows the user to read the location last written

to when the write operation is complete. CMOS design and pro-

cessing enables this part to be used in systems where reduced

power consumption and reliability are required. A complete family

of packages is offered to provide the utmost flexibility in applica-

tions.
