Abstract: The characteristics, structures and principles of the zero-power ultra-fast complex complex middle programming logic device ISPMACH4000z have been introduced by Latidi Semiconductor. The device's maximum standby current is less than 30μA, the maximum operating frequency can reach 265MHz, its low price and free software support enables the series of devices to various battery-based devices, the flexibility of complex programmable logic devices Expand to traditional consumer electronic fields. The flexibility of programmable logic devices (PLD, Programmable Logic Device has been loved by electronics engineers, but in various mobile consumer electronics markets remain ASIC chips. Several reasons hinder the CPLD device into the mobile device market, especially various battery-powered handheld devices. First, its high price, the second is its huge power consumption, and a factor is the operating frequency of the CPLD device. The same size CPLD and ASIC, the maximum operating frequency of CPLD is often lower than specially designed ASIC chips. Based on this situation, US Lateri Semiconductor Co., Ltd. launched an IspMach4000Z series device. The device breaks through the price and speed threshold encountered by the CPLD device into the mobile consumer electronics market. The introduction of the ISPMACH4000Z (In-System Programmable Macro Array CMOS High-Densigy) series is marked with the world of the third-generation BFW (Superbig, Superfast, Superwide) devices of Lattice. The highest operating frequency of this series of devices can reach 400MHz, which can fully meet most of the high-speed applications of contemporary consumer electronics. The ISPMACH4000Z series of devices launched in March 2003 uses the ISPMACH4000 device structure, which combines high speeds and low power consumption. The standby current of the series of devices is between 20 and 30 μA, which can be used in a battery-powered portable electronic device, while its maximum operating frequency can reach 265 MHz. 1 ISPMACH4000Z device feature ISPMACH4000Z device manufactured using advanced E2COMS 0.18μm process, its core operating voltage is 1.8V, and its main features are as follows: * Highly low static power consumption, typical static power consumption is 20μW. * Ultra-fast device structure, its pin delay (TPD) is 3.5 ns, the maximum operating frequency is 265MHz. * Has a variety of temperature ranges available: commercial grade (0 ~ 70 ° C), industrial grade (-40 ~ 85 ° C), automotive level (-40 ~ 125 ° C). * Flexible design, 3 device density (32, 64 and 128 macro units), 4 system clocks, each logic block has 36 inputs, each output can have up to 80 multiplier (PT, Product Terms) Output wiring pool (ORP, OUTPUT ROUTE POOL) provides free lock locking; * Has a flexible control signal, clock signal, and output enable signal (OE, OUTPUT Enable). * Pins and features are fully compatible with the ISPMACH4000V / B / C series devices. * Supports 3.3V, 2.5V and 1.8V standard interface voltages of LVTTL and LVCMS. * Has functions such as OpenDrain, Slowslew, bus maintenance, pull-pull, pull-up resistor, and PCI compatibility. * Meet the IEEE1532 and 1149.1 standards. * With 48 foot TQFP packages, 49 foot Cabga packages, 100-foot and 128 foot TQFP packages, etc., suitable for miniaturized portable devices. * Provide a full support platform for the IspMach4000Z series devices through Londi's ISplever software. Users can download the software from the company's website (www.latticesemi.com). 2 ISPMAC4000Z Structure The ISPMACH4000Z device consists of a plurality of universal logic blocks (GLB, Generic Logic Block), each GLB is coupled to GRP, GLOBAL ROUTE POOL, as shown in Figure 1. Each GLB has 16 macro units, 36 inputs. The output of 16 macro units is connected to the I / O block by outputting the wiring pool, but also to the GRP, and even if it feeds back to the same GLB, it must pass GRP, so that the connection between the GLB interpoded is constant and presented. Delay. Since each I / O can have different supply voltages, the device can be applied to a hybrid voltage environment. In the ISPMACH4000Z series, the ISPMACH4032ZC device contains two GLBs, ISPMACH4064ZC contains four, and ISPMACH4128ZC includes 8. The GLB consists of programmable and array, logical dispensers, 16 macro units and a clock generator, as shown in Figure 2. 3 ISPMACH4000Z Device Series ISPMACH4000Z has a 3-family device for use. Z represents zero power consumption in the device name, and C represents the core voltage of 1.8V. The package of IspMach4000Z devices is fully compatible with the corresponding ISPMACH4000 devices. Table 1 listed is the main parameters of the ISPMACH4000Z series devices.
