MAX1441 Datasheet, PDF (33/41 Pages) Maxim Integrated Products – Automotive, Two-Channel Proximity and Touch Sensor

Automotive, Two-Channel Proximity and
Touch Sensor
The device does not support individual word programming.
A whole page must be programmed at the same time. In
attempts to write to an individual word, the data intended
for the individual word is copied to the entire page.
CAUTION: It is the user’s responsibility to ensure that a
Flash high-voltage operation (erase or write) is allowed to
complete without external intervention. When an external
intervention such as POR, or asserting the reset pin, is
applied during a Flash high-voltage operation, the Flash
operation is aborted. This can cause irreversible dam-
age to the Flash and make the Flash inoperable.
Instruction Set
The device supports all the standard MAXQ20
instructions when executing from Flash and the utility
ROM (Table 12).
For a complete list of instructions and detailed
descriptions, refer to the MAXQ Family Instruction Set
Summary in the MAXQ Family User’s Guide.
