ATF1502AS(L)

Block Diagram

Each of the 32 macrocells generates a buried feedback that goes to the global bus. Each input

and I/O pin also feeds into the global bus. The switch matrix in each logic block then selects 40

individual signals from the global bus. Each macrocell also generates a foldback logic term

that goes to a regional bus. Cascade logic between macrocells in the ATF1502AS allows fast,

efficient generation of complex logic functions. The ATF1502AS contains four such logic

chains, each capable of creating sum term logic with a fan-in of up to 40 product terms.

The ATF1502AS macrocell, shown in Figure 1, is flexible enough to support highly complex

logic functions operating at high speed. The macrocell consists of five sections: product terms

and product term select multiplexer, OR/XOR/CASCADE logic, a flip-flop, output select and

enable, and logic array inputs.

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

sumption. A security fuse, when programmed, protects the contents of the ATF1502AS. 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 Signature is accessible regardless of

the state of the security fuse.

The ATF1502AS device is an in-system programmable (ISP) device. It uses the industry stan-

dard 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 programmed without remov-

ing 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.
