V
CC
, V
PP
AND RP# TRANSITIONS
The CUI latches commands as issued by
system
software and is not altered by V
PP
or CE#
transitions or WSM actions. Its default state upon
power-up, after exit from deep power-down mode,
or after V
CC
transitions above V
LKO
(lockout
voltage), is read array mode.
After any word/byte program or block erase
operation is complete and even after V
PP
transitions
down to V
PPLK
, the CUI must be reset to read array
mode via the Read Array command if accesses to
the flash memory are desired.
Please refer to Intel’s application note

, RP#,
and WP#
for a circuit-level description of how to
implement the protection discussed in Section 3.6.
3.7
Power Supply Decoupling
Flash memory’s power switching characteristics
require careful device decoupling methods. System
designers should consider three supply current
issues:
1.
Standby current levels (I
CCS
)
2.
Active current levels (I
CCR
)
3.
Transient peaks produced by falling and rising
edges of CE#.
Transient current magnitudes depend on the device
outputs’ capacitive and inductive loading. Two-line
control and proper decoupling capacitor selection
will suppress these transient voltage peaks. Each
flash device should have a 0.1 μF ceramic
capacitor connected between each V
CC
and GND,
and between its V
PP
and GND. These high-
frequency, inherently low-inductance capacitors
should be placed as close as possible to the
package leads.
3.7.1
V
TRACE ON PRINTED CIRCUIT
BOARDS
Designing for in-system programming of the flash
memory requires special consideration of the V
PP
power supply trace by the printed circuit board
designer. The V
PP
pin supplies the flash memory
cells current for programming and erasing. One
should use similar trace widths and layout
considerations given to the V
CC
power supply trace.
Adequate V
PP
supply traces, and decoupling
capacitors placed adjacent to the component, will
decrease spikes and overshoots.
