    摘要: In a programmable device employing antifuses, first digital logic transistors the gates of which will experience a programming voltage Vpp have a greater gate insulator thickness than do second digital logic transistors the gates of which will not experience the programming voltage. The first digital logic transistors may be logic module input device transistors. The first digital logic transistors may be transistors coupled to an enable input lead where the enable input lead is couplable to a tie-high conductor or to a tie-low conductor depending on which of two antifuses is programmed.

    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: The programmable logic of a programmable device is sectioned into four logic regions. Each logic region includes logic elements and a programmable interconnect structure employing antifuses for programmably interconnecting selected ones of those logic elements. Programming conductors for supplying programming current to antifuses of a logic region extend across the logic region but do not extend across other logic regions. Similarly, programming control conductors that control programming transistors of the logic region extend across the logic region but do not extend across other logic regions. The programmable device structure allows four antifuses to be programmed simultaneously, one antifuse in each logic region. An antifuse can be selected for simultaneous programming from a logic region, irrespective of the other three antifuses that are or may be selected for simultaneous programming from the other three logic regions. Four programming current multiplexers and four programming buses are provided for each logic region so that the programming current that programs each antifuse flows from a separate input terminal. The resistance of the programming conductors is reduced by the use of parallel strips of metal in multiple metal layers.

    摘要: To protect logic module output devices from high voltages, logic modules are not powered during antifuse programming. In some embodiments, two separate power input terminals VCC1 and VCC2 are provided: power input terminal VCC1 being coupled to power the logic modules, and power input terminal VCC2 being coupled to power the programming control circuitry. Power terminal VCC1 is left floating or is grounded during antifuse programming such that the logic modules are not powered but such that the programming circuitry is powered during antifuse programming via the second power terminal VCC2. Logic module output protection transistors are not required nor is the associated charge pump. Because the logic module input devices are not powered, a current surge through the input devices on power up does not occur and an internal disable signal and associated circuitry is not required. In one embodiment, the field programmable gate array is made smaller because it has no internal disable signal and associated circuitry, no logic module output protection transistors, and no charge pump that operates during normal circuit operation. In embodiments, power input terminal VCC2 is a high voltage compatible power input terminal.

    摘要翻译: 为了保护逻辑模块输出设备免受高电压的影响,逻辑模块在反熔丝编程期间未通电。 在一些实施例中,提供两个单独的电源输入端子VCC1和VCC2:电源输入端子VCC1被耦合以对逻辑模块供电,并且电源输入端子VCC2被耦合以对编程控制电路供电。 电源端子VCC1在反熔丝编程期间处于悬空状态或接地状态,使得逻辑模块未通电,而使编程电路在反熔丝编程期间通过第二电源端子VCC2供电。 不需要逻辑模块输出保护晶体管,也不需要相关的电荷泵。 由于逻辑模块输入设备未通电,所以不会在上电时通过输入设备产生电流浪涌,并且不需要内部禁用信号和相关电路。 在一个实施例中,由于现场可编程门阵列没有内部禁用信号和相关联的电路,没有逻辑模块输出保护晶体管,并且没有在正常电路操作期间操作的电荷泵,所以现场可编程门阵列被制造得更 在实施例中,电源输入端子VCC2是高电压兼容电力输入端子。

    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 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 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.
