V Program and Erase Voltages
PP
TheB3 flash memory device products provide in-system programming and erase at 2.7 V. For
customers requiring fast programming in their manufacturing environment, the B3 flash memory
device includes an additional low-cost 12-V programming feature.
The 12-V V mode enhances programming performance during the short period of time typically
PP
found in manufacturing processes. However, this mode is not intended for extended use. 12 V can
be applied to V during program and Erase operations for a maximum of 1000 cycles on the main
PP
blocks, and 2500 cycles on the parameter blocks. V can be connected to 12 V for a total of 80
PP
hours maximum.
Warning:
Stressing the flash memory device beyond these limits might cause permanent damage.
During Read operations or idle times, V can be tied to a 5-V supply. For Program and Erase
PP
operations, a 5-V supply is not permitted. The V must be supplied with either 2.7 V to 3.6 V or
PP
11.4 V to 12.6 V during Program and Erase operations.

VPP = VIL for Complete Protection
The V programming voltage can be held low for complete write protection of all blocks in the
PP
flash memory device. When V is below V
, any Program or Erase operation results in an
PP
PPLK
error, prompting the corresponding SR.3 to be set.
