CPU Supervisor with Nonvolatile Memory and
Programmable I/O
General Description
The DS4510 is a CPU supervisor with integrated 64-
byte EEPROM memory and four programmable, non-
volatile (NV) I/O pins. It is configured with an
industry-standard I
2
C interface using either fast-mode
(400kbps) or standard-mode (100kbps) communica-
tion. The I/O pins can be used as general-purpose I
2
C-
to-parallel I/O expander with unlimited read/write
capability. EEPROM registers allow the power-on value
of the I/O pins to be adjusted to keep track of the sys-
tem’s state through power cycles, and the CPU supervi-
sor’s timer can be adjusted between 125ms and
1000ms to meet most any application need.

J-STD-020A Specification
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
