This was the first micro embedded Matrix ever designed - meM57110 was made loosely compatible with SLG46110. Testing was done with NVM bitstreams generated with GreenPAK designer.

Proof of Concept (Revision 0.1)

After initial testing on S7-mini from BML (Xilinx Spartan-7 S25) standalone demo was implemented on XO2000 board with Lattice XO2-4000 FPGA. Bitstream loading over UART, simple ASCII protocol (R = reset, 0/1 send bit, S - Start).

Features implemented

• 1:1 bitstream compatible (512 bits) with SLG46110
• Matrix multiplexer
• Clock dividers/multiplexer
• all LUT and F/F (no latch function)
• counters: CNT0, CNT1, CNT3
• all I/O connected to PMOD pins
• user LED's connected to I/O output drivers
• user button connected to "PIN2" input

This configuration uses 640 (30%) of slices from the XO2-4000
