Bus Operation
The 3 Volt Advanced+ Stacked-CSP memory
devices read, program and erase in-system via the
local CPU or microcontroller. All bus cycles to or
from the Stacked-CSP conform to standard
microcontroller bus cycles. Four control balls dictate
the data flow in and out of the flash component:
F-CE#, F-OE#, F-WE# and F-RP#. Four control
balls handle the data flow in and out of the SRAM
component: S-CS
1
#, S-CS
2
, S-OE#, and S-WE#
These bus operations are summarized in Tables 2
and 3.
4.1.1
READ
The SRAM has one read mode while the flash
memory has four read modes: read array, read
configuration, read status and read query. These
flash
memory
read
modes
are
accessible
independent of the F-V
voltage. The appropriate
read mode command must be issued to the flash
memory to enter the corresponding mode. Upon
initial device power-up or after exit from reset, the
flash device automatically defaults to read array
mode.
F-CE# and F-OE# must be driven active to obtain
data from the flash component. at the outputs.
S-CS

#, S-CS

, and S-OE# must be driven active
to obtain data from the SRAM device. For all reads
operations, F-WE#, S-WE# and F-RP# must be at
V
IH
. Figure 6 illustrates a flash read cycle.
4.1.2
OUTPUT DISABLE
With F-OE# and S-OE# inactive, the Stacked-CSP
outputs are disabled. Output balls are placed in a
high-mpedance state.
