Lattice公司的MachXO2系列是非易失性的无限制重新配置的可编程逻辑器件(PLD),具有低容量PLD,低成本,低功耗和高系统集成度等特点,采用65nm闪存工艺技术,和MachXO PLD相比,逻辑容量增加3x,嵌入存储器曾加10x,静态功耗降低100x,查找表(LUT)从256 到 6864,主要用在系统应用如通信架构,计算,高端工业设备和高端医疗设备以及消费类电子如智能手机,GPS,数码相机和移动计算等.本文介绍了MachXO2系列主要特性, MachXO2-1200器件框图以及MachXO2 1200ZE评估板主要特性,方框图,电路图与材料清单.

The MachXO2 family of ultra low power, instant-on, non-volatile PLDs has six devices with densities ranging from 256 to 6864 Look-Up Tables (LUTs). In addition to LUT-based, low-cost programmable logic these devices feature Embedded Block RAM (EBR), Distributed RAM, User Flash Memory (UFM), Phase Locked Loops (PLLs), pre-engineered source synchronous I/O support, advanced configuration support including dual-boot capability and hardened versions of commonly used functions such as SPI controller, I2C controller and timer/counter. These fea-tures allow these devices to be used in low cost, high volume consumer and system applications. The MachXO2 devices are designed on a 65nm non-volatile low power process. The device architecture has sev-eral features such as programmable low swing differential I/Os and the ability to turn off I/O banks, on-chip PLLs and oscillators dynamically. These features help manage static and dynamic power consumption resulting in low static power for all members of the family. The MachXO2 devices are available in two versions – ultra low power (ZE) and high performance (HC and HE) devices.

The ultra low power devices are offered in three speed grades -1, -2 and -3, with -3 being the fastest. Sim-ilarly, the high-performance devices are offered in three speed grades: -4, -5 and -6, with -6 being the fastest. HC devices have an internal linear voltage regulator which supports external VCC supply voltages of 3.3V or 2.5V. ZE and HE devices only accept 1.2V as the external VCC supply voltage. With the exception of power supply voltage all three types of devices (ZE, HC and HE) are functionally compatible and pin compatible with each other. The MachXO2 PLDs are available in a broad range of advanced halogen-free packages ranging from the space saving 2.5x2.5 mm WLCSP to the 23x23 mm fpBGA. MachXO2 devices support density migration within the same package. Table 1-1 shows the LUT densities, package and I/O options, along with other key parameters. The pre-engineered source synchronous logic implemented in the MachXO2 device family supports a broad range of interface standards, including LPDDR, DDR, DDR2 and 7:1 gearing for display I/Os.

The MachXO2 devices offer enhanced I/O features such as drive strength control, slew rate control, PCI compati-bility, bus-keeper latches, pull-up resistors, pull-down resistors, open drain outputs and hot socketing. Pull-up, pull-down and bus-keeper features are controllable on a “per-pin” basis. A user-programmable internal oscillator is included in MachXO2 devices. The clock output from this oscillator may be divided by the timer/counter for use as clock input in functions such as LED control, key-board scanner and sim-ilar state machines. The MachXO2 devices also provide flexible, reliable and secure configuration from on-chip Flash memory. These devices can also configure themselves from external SPI Flash or be configured by an external master through the JTAG test access port or through the I2C port. Additionally, MachXO2 devices support dual-boot capability (using external Flash memory) and remote field upgrade (TransFR) capability. Lattice provides a variety of design tools that allow complex designs to be efficiently implemented using the MachXO2 family of devices. Popular logic synthesis tools provide synthesis library support for MachXO2. Lattice design tools use the synthesis tool output along with the user-specified preferences and constraints to place and route the design in the MachXO2 device. These tools extract the timing from the routing and back-annotate it into the design for timing verification. Lattice provides many pre-engineered IP (Intellectual Property) LatticeCORE™ modules, including a number of reference designs licensed free of charge, optimized for the MachXO2 PLD family. By using these configurable soft core IP cores as standardized blocks, users are free to concentrate on the unique aspects of their design, increas-ing their productivity.
