Intel NetStructure
80 (1980 is the first year supported by the PC), updates the century byte to 20. This feature enables
operating systems and applications using the BIOS date/time services to reliably manipulate the
year as a four-digit value.
A coin-cell battery located on the ZT 5524 / MPCBL5524 processor board powers the real-time
clock and CMOS memory. When the ZT 5524 / MPCBL5524 is not powered externally, the battery
has an estimated life of six years. When the ZT 5524 / MPCBL5524 is powered up, the 3.3 V
backplane current from the power supply extends the life of the battery.
The ZT 5524 / MPCBL5524’s real-time clock resides in the National Semiconductor PC87417 I/O
controller.A link to the datasheet for this device is available in
Speaker Interface
For external speaker interfacing, the ZT 5524 / MPCBL5524 supports an external AT-compatible
speaker through the RPIO connector J5. Connector locations and pinouts are documented in
Appendix A, “ZT 5524 / MPCBL5524 Connectors.”
Serial I/O
The ZT 5524 / MPCBL5524 provides two 16C550, PC-compatible serial ports:
Faceplate:
Rear Panel:
Both ports are compatible with RS-232 signaling levels and supports data transfers at speeds up to
115.2 Kbits/sec with BIOS support.

Keyboard/Mouse Controller
The ZT 5524 / MPCBL5524 includes an on-board PC/AT keyboard/mouse controller. Keyboard
and mouse signals are available at the faceplate via J8. A “Y” interface cable is required to use both
interfaces at once. The keyboard and mouse signals are also available through the RPIO connector
J5. For a diagram of the faceplate, see

PCI Video
The ZT 5524 / MPCBL5524 provides on-board video using the Chips and Technologies* 69000
HiQVideo Accelerator with Integrated Memory video device configured as a PCI device. The PCI
bus supports 32 bits of data and runs at a speed of 33 MHz, giving it a theoretical bandwidth of
133 MB/s. The 69000 provides support for display resolutions up to 1024 x 768.
