DS4510 - Maxim Integrated Products

DS4510 CPU Supervisor with Nonvolatile Memory and Programmable I/O

The DS4510 is a CPU supervisor with integrated 64byte EEPROM memory and four programmable, nonvolatile (NV) I/O pins. It is configured with an industry-standard I 2 C™ 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 capabilit.
