A) They are programmed on power up -- no loading from a serial prom.
B) I can program them with the demo PCB.
C) Lots of I/O pins ... well before you read the fine print.
D) PLCC packaging.
E) Low cost compared to a FPGA and serial rom.
point is E is a matter of debate since I spent about $100 on the
