3.3 Volt for Read and Write Operations

Simultaneous Read/Write Operation:

• Hardware method of locking a sector, either

in-system or using programming equipment, to

prevent any program or erase operation within

that sector

• Data can be continuously read from one bank

while executing erase/program functions in

another bank

• Temporary Sector Unprotect allows changing

data in protected sectors in-system

• Zero latency between read and write operations

Erase Suspend/Resume

ꢀ

• Suspends erase operations to allow programming

in same bank

Note: For programming information refer to Flash Programming
