8-MBIT SmartVoltage BOOT BLOCK FLASH MEMORY FAMILY
RP#
INPUT
RESET/DEEP POWER-DOWN:
Uses three voltage levels
(V
IL
, V
IH
, and V
HH
) to control two different functions:
reset/deep power-down mode and boot block unlocking. It is
backwards-compatible with the BX/BL/BV products.
When RP# is at logic low, the device is in reset/deep
power-down mode,
which puts the outputs at High-Z, resets
the Write State Machine, and draws minimum current.
When RP# is at logic high, the device is in standard
operation.
When RP# transitions from logic-low to logic-
high, the device defaults to the read array mode.
When RP# is at V
HH
, the boot block is unlocked
and can be
programmed or erased. This overrides any control from the
WP# input.
