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 I² C^TM interface using either fast-mode (400kbps) or standard-mode (100kbps) commu-nication. The I/O pins can be used as general-purpose I² 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.
