DESCRIPTION
The X88C64 SLIC E2 is a highly integrated E2 Micro-
controller peripheral which combines the functional-
ity of the X88C64 component with pre-loaded soft-
ware routines allowing any embedded system using
it to upgrade and download software via the serial
port. This self-loading integrated code eliminates the
need to initially program the firmware into a memory
device at the time of initial manufacture. The SLIC
routines also greatly facilitate the loading of subse-
quent versions of the firmware into the system.
The SLIC routines consist of approximately 500 bytes
of instructions for the 8051 which will initialize the
microcontroller and its on-board UART and download
the user’s software through the UART. The baud rate
for the transfer is 9600 based on a crystal frequency
of 11MHz. Data transfer is accomplished using a
proprietary format called XCOM. Xicor also has de-
veloped a program for IBM PCs and compatibles
called XSLIC, which will translate an Intel HEX format
file into XCOM format and upload the program to an
X88C64 SLIC E2.
The X88C64 device itself is an 8K x 8 E2PROM
fabricated with advanced CMOS Textured Poly Float-
