ST92163 DEMO BOARD CHARACTERISTICS

2.2.8 EXTERNAL MEMORIES

To offer you more flexibility , two external memories can be used directly with the ST92163

DEMO BOARD. To use the 32K of RAM or the 64K EPROM or FLASH ROM you just have to

put a jumper on the corresponding chip enable slot (JP2 for RAM and JP1 for EPROM/

FLASH).

The latch buffer (U4) is mandatory because the P0 port is multiplexed when you address ex-

ternal memory.

2.2.9 POWER SUPPLY CONNECTOR

The ST92163 Demo Board can be powered either through a jack allowing the use of an ex-

ternal AC/DC transformer or through the J2 connector allowing the power to be supplied from

an internal PC 5”1/4 power supply connector.

Note that by using jumper W1, you can choose to power your board from the VCC supplied by

on the on-board power supply (self power) or from the VCC supplied by the USB cable (bus

power).
