ATF1504ASV(L)

Block Diagram

Unused product terms are automatically disabled by the compiler to decrease power

consumption. A security fuse, when programmed, protects the contents of the

ATF1504ASV(L). Two bytes (16 bits) of User Signature are accessible to the user for

purposes such as storing project name, part number, revision or date. The User Signa-

ture is accessible regardless of the state of the security fuse.

The ATF1504ASV(L) device is an in-system programmable (ISP) device. It uses the

industry-standard 4-pin JTAG interface (IEEE Std. 1149.1), and is fully-compliant with

JTAG’s Boundary-scan Description Language (BSDL). ISP allows the device to be pro-

grammed without removing it from the printed circuit board. In addition to simplifying the

manufacturing flow, ISP also allows design modifications to be made in the field via

software.

Product Terms and Select

Mux

Each ATF1504ASV(L) macrocell has five product terms. Each product term receives as

its inputs all signals from both the global bus and regional bus.

The product term select multiplexer (PTMUX) allocates the five product terms as

needed to the macrocell logic gates and control signals. The PTMUX programming is

determined by the design compiler, which selects the optimum macrocell configuration.
