摘要： A programmable circuit, such as a field programmable gate array, and a dedicated device, such as an ASIC type device, are coupled together with an antifuse based interface on a single integrated circuit. A configurable non-volatile memory that communicates with the dedicated device is also located on the integrated circuit. The platform for the programmable circuit is one half of an existing programmable circuit, which eliminates the need to engineer the programmable circuit. The programmable circuit includes a clock network that receives clock signals from clock terminals as well as from a clock network in the dedicated device. The interface between the dedicated device and programmable circuit includes a number of conductors with buffers with testing circuitry. The testing circuitry includes a PMOS test transistor and a NMOS test transistor which permits testing of the buffers without programming the antifuses coupled to the conductors. The input/output terminals around the periphery and in the interface between the programmable circuit and dedicated device are tested using JTAG registers. The path of the test signal through the JTAG registers is selectable to pass around the periphery of both the programmable and dedicated devices or through the interface and around the periphery of only one of the programmable and dedicated devices.

摘要： A field programmable gate array includes a programmable interconnect structure and plurality of logic cells. The logic cells each include a number of combinatorial logic circuits, which have direct interconnections with the programmable interconnect structure, and a plurality of sequential logic element, such as D type flip-flops that acts as registers. The combinatorial logic circuits may be directly connected to the programmable interconnect structure as well as connected to the input terminals of the sequential logic elements. Consequently, the logic cells include both combinatorial and registered connections with the programmable interconnect structure. Moreover, one of the sequential elements may selectively receive a dedicated input from the programmable interconnect structure. The output leads of the logic cell is connected to the programmable interconnect structure through a driver that includes a protection transistor. The gate of the protection transistor is coupled to a primary charge pump that is shared with multiple drivers as well as a secondary charge pump associated with the driver.

摘要： A field programmable gate array has a security antifuse which when programmed prevents readout of data indicative of how the interconnect structure is programmed but which does not prevent readout of data indicative of which other antifuses are programmed. In some embodiments, the programming control shift registers adjacent the left and right sides are the field programmable gate array are disabled when the security antifuse is programmed but the programming control shift registers adjacent the top and bottom sides of the field programmable gate array are not disabled. A second security antifuse is also provided which when programmed disables a JTAG boundary scan register but does not disable a JTAG bypass register. Information can therefore be shifted through the JTAG test circuitry without allowing the JTAG circuitry to be used to extract information indicative of how the interconnect structure is programmed. Logic module and interface cell scan paths are provided and special test instructions are supported which allow test vectors to be loaded into the logic module and interface cell scan paths.

摘要： A multi-lamp fluorescent light fixture includes a plurality of replaceable fluorescent lamp starter units. Each starter unit has a built-in microcontroller, an RF (Radio-Frequency) receiver, and communicates wirelessly with a master unit. The plurality of starter units can be wirelessly controlled to dim the multi-lamp fixture. Each starter unit receives a DIM command. Each starter unit identified as a dimmer starter unit responds to the DIM command by turning off coupled fluorescent lamps. Starter units not identified as dimmer starter units respond by leaving coupled lamps turned on, or alternatively, turning off and quickly restarting coupled lamps. Systems of existing light fixtures are retrofitted with such wireless starter units, and thereby made controllable by a master unit so that the master unit can dim the lights if room occupancy is not detected or if sufficient ambient light is available.

摘要： A programmable integrated circuit (see FIG. 9) has a plurality of L-shaped programming power buses (for example, 126, 130, 129 and 127) that extend along sides of the integrated circuit. Each L-shaped programming power bus extends along two adjacent sides of the integrated circuit such that legs of two L-shaped programming power buses extend along each of the sides. There are four pluralities of programming drivers (for example, 110, 117, 115 and 112), one plurality being associated with each of the four sides. There are also four programming current multiplexers (for example, 118, 125, 123 and 120), one associated with each of the sides. A programming driver of one of the plurality of programming drivers is selectively couplable to one of the two L-shaped programming power bus legs that extends along the associated side of the integrated circuit via the programming current multiplexer associated with that side. Additional pluralities of programming drivers and additional programming current multiplexers can be provided.

摘要： A general purpose BGA security cap includes a substrate, an integrated circuit die, and an array of bond balls. The substrate includes an anti-tamper security mesh of conductors. The bond balls include outer bond balls and inner bond balls that are fixed to the underside of the substrate. The integrated circuit drives and monitors the anti-tamper security mesh and communicates data using a serial physical interface through a subset of the inner bond balls. In one example, a user has circuitry to be protected. The user purchases the BGA security cap and fits it over the circuitry to be protected such that the integrated circuit of the security cap communicates tamper detect condition information via the serial interface to the underlying protected circuitry and causes sensitive information to be erased or a program to be halted in the event of a tamper condition.

摘要： A package-on-package (POP) secure module includes a BGA mesh cap, a first BGA package, and a second BGA package. The first BGA package includes a first integrated circuit (for example, a microcontroller that includes tamper detect logic). The second BGA package includes a second integrated circuit (for example, a memory). The second BGA package is piggy-back mounted to the first BGA package and the BGA mesh cap is piggy-back mounted to the second BGA package. A printed circuit board substrate member of the BGA mesh cap includes an embedded anti-tamper mesh. This mesh is connected in a protected manner within the module to the first integrated circuit. When the module is in use, a mesh embedded in an underlying printed circuit board is coupled to the BGA cap mesh so that both anti-tamper meshes are controlled by the tamper detect logic.

摘要： A programmable device has digital logic elements and a programmable interconnect structure employing antifuses, the antifuses being programmable to connect selected ones of the digital logic elements together. During normal circuit operation, a first power input terminal is used to power the digital logic elements with a first supply voltage received on the first power input terminal. During normal circuit operation, a second power input terminal is used to protect circuitry of the programmable device from high voltage signals that may be driven onto terminals of the programmable device by circuitry external to the programmable device. During antifuse programming, the second power input terminal is used to drive charge pumps of programming drivers and/or programming control drivers. In some embodiments, the second power input terminal receives a voltage higher than the first supply voltage during antifuse programming such that the oscillating signal that drives the charge pumps has a larger amplitude thereby allowing back bias threshold voltages of transistors in the charge pumps to be overcome, facilitating starting of the charge pumps, and/or increasing charge pump efficiency.
