30 FAQ’s for Actel’s Antifuse FPGA Programming

85. Does Actel recommend programming a commercial part before

programming an RH/RT part?

Ans. Before programming a RadHard or RadTolerant device, Actel recommends that you program a

commercially equivalent device to ensure the proper setup of the hardware and software. After you have

successfully programmed a commercial device, you can program your RH or RT device.

86. Where can I find the lot number and date code on Actel FPGAs?

Ans. To trace a device lot history from qualification test records, Actel must have the lot number of the

device under investigation. The lot number allows Actel to identify the silicon ingot and wafer from which

the device was fabricated.

For most Actel FPGAs, the lot number is printed on the bottom of the package and the date code is on

the top, although there are exceptions. In either case, the lot number is easy to identify given the following

example:

Lot Number: 2ACT312381

Date Code: 9919

The date code indicates that the device is fabricated in the 19

week of 1999, and the wafer is from lot

number 2ACT312381.

87. Are the electrical characteristics of the device guaranteed after

programming? Is it necessary to perform functional tests on the

programmed units?

Ans. The electrical characteristics outlined in the Actel device datasheet are guaranteed for all devices

that pass programming provided proper electro static discharge (ESD) and device handling procedures

are followed. Additionally, correct functional behavior is guaranteed for all devices that pass

programming.

88. Can I program the antifuse devices on board?

Ans. No, Actel neither recommends, nor supports this.

89. Is it possible to program antifuse devices in automatic testing

equipment?

Ans. No, you can only program Actel’s antifuse devices using Silicon Sculptor II or 3 and equivalent BP

programmers.
