DS4510
CPU Supervisor with Nonvolatile Memory and Programmable I/O
|
Status
Active: In Production.
Description
The DS4510 is a CPU supervisor with integrated 64-byte EEPROM memory and four programmable, nonvolatile (NV) I/O pins. It is configured with an industry-standard I²C interface using either fastmode (400kbps) or standard-mode (100kbps) communication. The I/O pins can be used as general-purpose I²C-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 system's state through power cycles, and the CPU supervisor's timer can be adjusted between 125ms and 1000ms to meet most any application need.
