Introduction
The LatticeSC family of FPGAs combines a high-performance FPGA fabric, high-speed SERDES, high-perfor-
mance I/Os and large embedded RAM in a single industry leading architecture. This FPGA family is fabricated in a
state of the art technology to provide one of the highest performing FPGAs in the industry.
This family of devices includes features to meet the needs of today’s communication network systems. These fea-
tures include SERDES with embedded advance PCS (Physical Coding sub-layer), up to 7.8 Mbits of sysMEM
embedded block RAM, dedicated logic to support system level standards such as RAPIDIO, SPI4.2, SFI-4, UTO-
PIA, XGMII and CSIX. The devices in this family feature clock multiply, divide and phase shift PLLs, numerous

Introduction
LatticeSC/M Family Data Sheet
DLLs and dynamic glitch free clock MUXs which are required in today’s high end system designs. High-speed,
high-bandwidth I/O make this family ideal for high-throughput systems.
The ispLEVER
®
design tool from Lattice allows large complex designs to be efficiently implemented using the Lat-
ticeSC family of FPGA devices. Synthesis library support for LatticeSC is available for popular logic synthesis tools.
The ispLEVER tool uses the synthesis tool output along with the constraints from its floor planning tools to place
and route the design in the LatticeSC device. The ispLEVER tool extracts the timing from the routing and back-
annotates it into the design for timing verification.
Lattice provides many pre-designed IP (Intellectual Property) ispLeverCORE™ modules for the LatticeSC family.
By using these IPs as standardized blocks, designers are free to concentrate on the unique aspects of their design,

引 言 MAX6636是一个多通道的精密温度监测器，它不仅能监测本地温度，并且外部最多能接6个二极管。每一通道都具有可编程过低温度报警，1、4、5和6通道还具有可编程过高温度报警。当某一通道测得的温度达到其预先设定的极限值时，状态寄存器的相应位就会被置位。MAX6636最显著的优点是采用了微型20引脚TSS OP 封装，能够监测 CPU 和其他4个位置的温度，主要应用于台式电脑、笔记...[详细]
