Micro M48T86PC1 module for the real time clock function This module contains the lithium battery 32 768 kHz crystal and a RTC chip with 114 bytes of battery backed CMOS RAM It is guaranteed to maintain clock operation for a minimum of 10 years in the absence of power Both the internal RTC and the TS 5620 RTC are totally compatible with the Motorola 146818 chip used in the original PC It is located at the standard PC I O addresses of Hex 070 and 071 The top 48 bytes index 50h through 7Fh are not used by the BIOS and are available for user applications However since the TS 5700 uses an EEPROM to make this data non volatile a special method must be used to make any user data non volatile If you wish to use this area for non volatile storage contact Technologic Systems for details The CMOS RAM that is located inside the RTC chip is used to hold all of the BIOS set up parameters This RAM is always non volatile even when using the internal RTC All of the set up parameters are stored in a non volatile EEPROM chip The data stored in the EEPROM is copied into the CMOS RAM during every boot cycle This is all totally transparent and appears to operate as a standard CMOS set up RAM The schematic for the TS 5620 is posted on our website The TS 5620 design only uses two chips This circuitry can be freely used on any customer peripheral board design if the battery backed RTC feature is necessary The TS 5700 internal RTC is capable of ge
