AutoStore™ / POWER-UP RECALL
(VCC = 5.0V ± 10%)e
Note r:
tRESTORE starts from the time VCC rises above VSWITCH.
Note s: HSB is asserted low for 1
µs when VCAP drops through VSWITCH. If an SRAM write has not taken place since the last nonvolatile cycle, HSB will
be released and no STORE will take place.
AutoStore™ / POWER-UP RECALL
NO.
