The initialization values are loaded into the Flash memory during device programming and into the SRAM at power up or whenever the device is reconfigured. Four- input logic functions are generated by programming the LUT4.

Lattice LFXPE-5FCES FPGA – Process Review

Serial TAG memory is also available to allow the storage of small amounts of data such as calibration coefficients and error codes. While the LatticeXP2 does not require any speci? The current sense resistors are 10mOhm in value.

Replaceable oscillator for reference clocks? The secondary clock muxes are located in the center of the device. The order is arbitrary, and is not a power-sequencing guideline for the LatticeXP2. An external pull-up resistor of 4.


Lfzp2 can be run on a programmed device when the user logic is not active. There are seven outputs: Timing Adders are characterized but not tested on every device. DB9 pin 7 The evaluation board has features designed to make it easier to locate resources on the board and resources connected to the FPGA.


The input voltage is regulated down with a zener diode and a transistor.


The input voltage is supplied via J9, a coaxial DC input jack. The LatticeXP2 board provides a low-voltage 3. USB Cable for programming? Although the word size and number of words for each port varies, this mapping scheme applies to each port.

The MachXO can be reprogrammed with custom logic using connector J A 1×10 cable not supplied can be connected locally to J33 and the opposite end of the cable can be attached to another system that has a JTAG chain. This standard is emulated using complementary LVC- MOS outputs in conjunction with a parallel resistor across the driver outputs.

These are intended to generate a slower-speed system clock from a high-speed edge clock. Adjacent to U3 and U6 are current sense resistors. The next voltage supply to be enabled is the 3.

If an input delay is desired, designers can select either a fixed delay or a dynamic delay DEL[3: Where appropriate, the soft- ware will construct these using distributed memory primitives that represent the capabilities of the PFU. The PIC logic also includes pre-engineered support to aid in the implementation of high speed source synchronous standards such as 7: Table lists the signals associated with Slice 0 to Slice 2.

The routing resources consist of switching circuitry, buffers and metal interconnect routing seg- ments. Pattern represents a “blank” configuration data file. This signal is used to control the polarity of the clock to the synchronizing registers. This allows the DC regulation from the 5V input to be performed with loose tolerances and inexpensive components.


Similarly, the operand widths cannot be mixed within a block. The coaxial connector is located at the southwest side of the board. Actual delays at nominal temperature and voltage for best case process, can be much better than the values given in the tables. Figure shows the primary clock sources. It does not turn on any other supply on the board until the 1.

The benefit of region-based resources is the relatively low injection delay and skew within the region, as compared to primary clocks. This is the factory default con? It is capable of running from an input supply less than 3.

During configuration, an internal pull-up is enabled. LCD connector with backlight and contrast controls?

Cable or USB cable. The oscillator and CCLK run continuously and are available to user logic after configuration is complete.

Figure shows the selection muxes for these clocks. Exact performance may vary with device, design and tool version.
