Little Board™/486e Technical Manual

Byte-Wide Socket (S0)

The Little Board/486e CPU has a 32-pin onboard byte-wide memory socket designated S0. This socket supports 32-pin DIP JEDEC pin out memory devices, including EPROM, FLASH EPROM, SRAM, and nonvolatile RAM (NOVRAM) devices.

A memory device installed in the byte-wide socket can be used for:

!Simple program storage

!BIOS extension

!Solid State Disk (SDD)

Table 2–35 shows representative byte-wide memory devices that can be installed in the byte-wide socket. The table gives examples of generic part numbers, the size of the device (K bytes), and the DIP package pin count. It also lists the SSD device type, used by the Ampro Solid State Disk (SSD) Support Software to identify memory devices.
