28F160S3, 28F320S3
The device incorporates two Write Buffers of 32
bytes (16 words) to allow optimum-performance
data programming. This feature can improve
system program performance by up to four times
over non-buffer programming.
Individual block locking uses a combination of block
lock-bits to lock and unlock blocks. Block lock-bits
gate block erase, full chip erase, program and write
to
operations (Set Block Lock-Bit and Clear Block
Lock-Bits commands) set and clear lock-bits.
The Status Register and the STS pin in RY/BY#
mode indicate whether or not the device is busy
executing an operation or ready for a new
command. Polling the Status Register, system
software retrieves WSM feedback. STS in RY/BY#
mode gives an additional indicator of WSM activity
by providing a hardware status signal. Like the
Status Register, RY/BY#-low indicates that the
WSM is performing a block erase, program, or lock-
bit operation. RY/BY#-high indicates that the WSM
is ready for a new command, block erase is
suspended (and program is inactive), program is
suspended, or the device is in deep power-down
mode.

The Automatic Power Savings (APS) feature
substantially reduces active current when the
device is in static mode (addresses not switching).
The BYTE# pin allows either x8 or x16 read/writes
to the device. BYTE# at logic low selects 8-bit
mode with address A
byte and high byte. BYTE# at logic high enables
16-bit operation with address A
lowest order address. Address A

power-down mode which significantly reduces
power consumption, provides write protection,
resets the device, and clears the Status Register. A
