densest EPLD of this size. Eight dedicated inputs and 16
bidirectional I/O pins communicate to one logic array block. In
the CY7C344B LAB there are 32 macrocells and 64 expander
product terms. When an I/O macrocell is used as an input, two
expanders are used to create an input path. Even if all of the
I/O pins are driven by macrocell registers, there are still 16
“buried” registers available. All inputs, macrocells, and I/O pins
are interconnected within the LAB.
The speed and density of the CY7C344B makes it a natural
for all types of applications. With just this one device, the
designer can implement complex state machines, registered
logic, and combinatorial “glue” logic, without using multiple
chips. This architectural flexibility allows the CY7C344B to
replace
synchronous, asynchronous, combinatorial, or all three.
