6000 Series user’s manual Overview
SETUP information stored in EEPROM for high reliability
The loss of SETUP data is serious in industrial applications. In the
PC Microcontroller, SETUP data is stored in nonvolatile serial
EEPROM eliminating the problem with battery or power failure
(with the exception of time and date). 512 bytes of the serial
EEPROM are reserved by the BIOS. An additional 1536 bytes are
available to the user. A software driver is supplied for accessing the
EEPROM.
Real time calendar/clock with battery backup
The PC Microcontroller has a built-in AT style, real time clock. The
real time clock is powered by an external AT style battery. For
additional backup, an on-card battery powers the calendar/clock when
the external battery is being replaced. The clock may be read either
through DOS or CAMBASIC. The calendar/clock also provides the
user with 128 bytes of user-defined CMOS-RAM.
Note: The date and time occasionally res
e
ts to default. If your applica-
tion requires date/time stamping you should consider another Octa-
gon Systems CPU card.
Power management reduces power by more than 70%
Power management can be used to reduce power consumption or to
freeze the state of the program on the occurrence of a power manage-
ment interrupt. Power consumption can be reduced by more than 70%,
reducing the heat load and extending battery life in mobile applications.
Rugged environmental operation
The CPU case temperature may range from -40° to 85°C during opera-
tion at 25 MHz, or 0° to 60° C during operation at 40 MHz. The PC
Microcontroller is designed to withstand 10g shock and 2g vibration.
5 volt only operation lowers system cost
The PC Microcontroller operates from a single 5V ± 4% supply. Lo-
cated across the power supply, the 6.2V, 5W diode protects against
reverse voltage and limits over voltage. Power is supplied to the card
either through the ISA bus connector or the terminal block.
