... At each density there are two packaging op- tions to choose from—one that is I/O intensive and another that is register intensive. For example, the CY7C374 and CY7C375 both feature 128 macrocells. On the CY7C374, available in an 84-pin package, half of the macrocells are bur- ied and half are available on I/O pins ...

Of the 86 product terms, 80 are for general-purpose use for the 16 macrocells in the logic block. Four of the remaining six prod- uct terms in the logic block are output enable (OE) product terms. Each of the OE ...

At the output of the macrocell, a polarity control mux is avail- able to select active LOW or active HIGH signals. This has the added advantage of allowing significant logic reduction to oc- cur in many applications. The F 370 ...
