to 2 megabytes by replacing the devices at locations U24, U25, U27, and U28 with larger
devices. The flash memory devices require +5 volts.
There are a total of eight 52-pin PLCC sockets on the EVB (U19, U20, U21, U22, U29, U30,
U31, and U32) for synchronous static RAM (SSRAM) devices. These sockets are paired as upper
and lower words and organized for long-word (32 bits wide) data transfers. Each pair is referred
to as BANKx.
The SSRAM factory default for the EVB is 128 kilobytes installed in BANK1 (U19 and U29).
These devices have 9 nanosecond access times and zero wait state cycles. On-board SSRAM may
be expanded to 256 kilobytes by replacing the devices at locations U19 and U29 with larger
devices.
Alternately, you may increase the amount of on-board SSRAM by populating U20, U21, U22,
U30, U31, and U32 with additional SSRAM devices. You may increase the SSRAM size up to 1
megabytes. (For information on increasing on-board memory see paragraph 2.2.9.)
The EVB includes an optional SCSI-2 port connection on the MPC505. The required parts are
not provided, and the user may add them if the SCSI port is needed. A list of the required parts
are provided in Chapter 2.
