com DS28DG02 2Kb SPI EEPROM with PIO, RTC, Reset, Battery Monitor, and Watchdog GENERAL DESCRIPTION The DS28DG02 combines 2Kb (256 x 8) EEPROM with 12 PIO lines, a real-time clock (RTC) and calendar with alarm function, a CPU reset monitor, a battery monitor, and a watchdog.
Communication with the device is accomplished with an industrystandard SPI™ interface.
The user EEPROM is organized as four blocks of 64 bytes each with single-byte and up to 16-byte page write capability.
Additional registers provide access to PIOs and to setup functions.
Individual PIO lines can be configured as inputs or outputs.
The power-on state of PIOs programmed as outputs is stored in nonvolatile (NV) memory.
All PIOs may be reconfigured by the user through the serial interface.
The RTC/calendar operates in the 12/24-hour format and automatically corrects for leap years.
Battery monitor threshold and watchdog timeout are userprogrammable through NV registers.
