POWER-ON RESET OUTPUT
All microprocessors have a reset input which forc-
es them to a known state when starting. The
M40Z300/W has a reset output (RST) pin which is
guaranteed to be low within t
WPT
of V
PFD
(See Ta-
ble 7). This signal is an open drain configuration.
An appropriate pull-up resistor should be chosen
to control the rise time. This signal will be valid for
all voltage conditions, even when V
CC
equals V
SS
.
Once V
CC
exceeds the power failure detect volt-
age V
PFD
, an internal timer keeps RST low for
t
REC
to allow the power supply to stabilize.
TWO TO FOUR DECODE
The M40Z300/W includes a 2 input (A, B) decoder
which allows the control of up to 4 independent
SRAMs. The Truth Table for these inputs is shown
in Table 3.
