X88C64D

The X88C64 SLIC E2 is designed as a highly integrated E2 Microcontroller peripheral which combines the functionality of the X88C64 component with pre-loaded software 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 subsequent versions of the firmware into the system.

Features of the X88C64 can be summarized as:(1)automatically downloads user's software into 8051 based systems;(2)features load, verify, and block protection capabilities;(3)transfers baud rate 9600 at 11MHz;(4)multiplexed address/data bus:-direct interface to popular 8051 family;(5)block protect register:-individually set write lock out in 1K blocks;(6)toggle bit polling:-early end of write detection;(7)page mode write:-allows up to 32 bytes to be written in one write cycle.

The X88C64 is internally configured as two independent 4K x 8 memory arrays. This feature provides the ability to perform nonvolatile memory updates in one array and continue operation out of code stored in the other array; effectively eliminating the need for an auxiliary memory device for code storage.
