The Scenix SX 48 or 52 has 48 or 52 pins on the package with 5, 8 bit ports
(A-E) for 40 io pins; not 52. Some pins are osc, /mclr, power, etc... They
are really nice chips, if you can stand smt. See:

Scenix makes a 50mhz, 20ns per instruction controller called the SX52 and is
has, you guessed it, 52 lines of digital I/O. It is also In System
Programmable. I strongly recommend examining their product line.
