WARNING

Lithium batteries incorporate inflammable materials such as lithium and organic solvents. If lithium batteries are mistreated or handled incorrectly, they may burst open and ignite, possible resulting in injury and/or fire. When dealing with lithium batteries, carefully follow the precautions listed below in order to prevent accidents.

❏Do not short circuit.

❏Do not disassemble, deform, or apply excessive pressure.

❏Do not heat or incinerate.

❏Do not apply solder directly.

❏Do not use different models, or new and old batteries together.

❏Do not charge.

❏Always check proper polarity.

To remove the battery from the module, carefully pull the battery from the socket.

Before installing a new battery, ensure that the battery pins are clean. Note the battery polarity and press the battery into the socket. When the battery is in the socket, no soldering is required.

EPROM and Flash

The MVME162 implementation includes 1 MB of Flash memory (an 8-Mbit Flash device organized as a 1M X 8, or four 2-Mbit Flash devices organized as 256Kbit x 8). For information on programming Flash, refer to the Intel documents listed in Related Documentation in this chapter. The EPROM location is a standard JEDEC 32-pin PLCC capable of 4 Mbit densities organized as a 512 KB X 8 device. Depending on a jumper setting (GPIO3, pins 9-10 on J22), the MC68xx040 reset code can be fetched from either the Flash (GPIO3 installed) or EPROM (GPIO3 removed).

Battery Backed Up RAM and Clock

The MK48T08 RAM and clock chip is used on the MVME162. This chip pro- vides a time of day clock, oscillator, crystal, power failure detection, memory write protection, 8KB of RAM, and a battery in one 28-pin package. The clock provides seconds, minutes, hours, day, date, month, and year in BCD 24-hour format. Corrections for 28- day, 29-day (leap year), and 30-day months are automatically made. No interrupts are generated by the clock. The MK48T08
