32 BURST-PIPELINED HIGH-SPEED
CMOS STATIC RAM
Publication Release Date: Septermber 1996

Revision A4
GENERAL DESCRIPTION
The W25P012A is a high-speed, low-power, synchronous-burst pipelined, CMOS static RAM
organized as 32,768
×
32 bits that operates on a single 3.3-volt power supply. A built-in two-bit burst
address counter supports both Pentium
burst mode and linear burst mode. The mode to be
executed is controlled by the LBO pin. Pipelining or non-pipelining of the data outputs is controlled by
the FT pin. A snooze mode reduces power dissipation.
The W25P012A supports both 2T/2T mode and 2T/1T mode which can be selected by pin 42. The
default mode is 2T/1T, with pin 42 low. To switch to 2T/2T mode, bias pin 42 to V
DDQ
. The state of
pin 42 should not be changed after power up. The 2T/2T mode will sustain one cycle of valid data
output in a burst read cycle when the device is deselected by CE2/CE3. This mode supports 3-1-1-1-
1-1-1-1 in a two-bank, back-to-back burst read cycle. On the other hand, the 2T/1T mode disable data
output within one cycle in a burst read cycle when the device is deselected by CE2/CE3. In this
mode, the device supports only 3-1-1-1-2-1-1-1 in a two-bank, back-to-back burst read cycle.
