ATF1504ASV/ATF1504ASVL

Block Diagram

Unused product terms are automatically disabled by

the compiler to decrease power consumption. A secu-

rity 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 Signature is accessible regardless of the

state of the security fuse.

The

ATF1504ASV(L)

device

in-system

programmable

(ISP)

device.

uses

the

industry-standard 4-pin JTAG interface (IEEE Std.

1149.1),

and

fully

compliant

with

JTAG’s

Boundary-scan Description Language (BSDL). ISP

allows the device to be programmed 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.
