Rad Hard Real Time Clock
• From Evatronics Design Guide on Real Time Clock for 8051XC
– The Real Time Clock realizes a real =me count with a resolu=on of 1/256th second. It allows the user to read seconds, minutes, hours, day of the week and the date. The date is represented by a 16-‐bit number, which value is interpreted by the user socware. The RTC enables a count of 179 years. The RTC features an alarm func=on which may be used to generate interrupts at a given =me during a day or periodically. These interrupts may be used to resume opera=on from the IDLE/DEEP SLEEP mode at a given =me.

Silicon Verifica=on of Support Chip EEPROM Interface
Rad Hard Support Chip ASIC designed so that System on a Chip (SoC) ASICs can Bootup from Rad Hard Parallel EEPROMS or Read Data from Parallel EEPROM and Program the EEPROM.
• The chip provides a Slave SPI Interface to Parallel EEPROMs. • We have verified that we can program a parallel EEPROM via the SPI Slave interface of the Support Chip. • Support for 16 MBytes or 128 MBits of Storage. • We have demonstrated that the Rad Hard Parallel EEPROMs in space can be reprogrammed using the Support Chip via a SPI interface.
