General Description
AGM CPLD family provides low－cost instant－on， non－volatile CPLDs， with densities from 256， 272 to 576 logic LUTs and non－volatile flash storage of 256Kbits。 The devices offer up to 144 I／O pins featuring with a user flash memory （UFM）， and in－system programming。 The devices are designed to reduce cost and power while providing programmable solutions for a  wide range of applications。
 Features
