技术资料 Spartan-6 datasheet Spartan系列FPGA芯片
Spartane-6 LXand LXT FPGAs are available in various speed grades, with -3 having the highest performance. The DC and AC electrical parameters of the Automotive XA Spartan-6 FPGAs and Defense-grade Spartan-6Q FPGAs devices are equivalent to the commercial specifications except where noted. The timing ...
技术资料 使用SpecctraQuest仿真时序问题
通常我们在计算时许问题时，一般重点遵循以下两个条件以保证足够的Timing Margin：
1. Tflightmax + Driver(Tcomax) + Skew + Jitter + Crosstalk + Receiver(Setup)< Clock Period
2. Tflightmin + Driver(Tcomin) - Receiver(Hold) - Skew - Crosstalk > 0
其中Driver的Tco一般可以从器件的Datasheet上查到。 ...

单片机编程 3.3v看门狗芯片
The STWD100 watchdog timer circuits are self-contained devices which prevent systemfailures that are caused by certain types of hardware errors (non-responding peripherals,bus contention, etc.) or software errors (bad code jump, code stuck in loop, etc.).The STWD100 watchdog timer has an input, WDI, ...
电源技术 利用高压看门狗定时器加强汽车安全系统
&nbsp;
Abstract: As electronic systems take over many of the mechanical functions in a car&mdash;ranging from engine timing to steering andbraking&mdash;there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" ...

单片机编程 CAT28LV64-64Kb CMOS并行EEPROM数据手
The CAT28LV64 is a low voltage, low power, CMOS Parallel EEPROM organized as 8K x 8&#8722;bits. It requires a simple interface for in&#8722;system programming. On&#8722;chip address and data latches, self&#8722;timed write cycle with auto&#8722;clear and VCC power up/down write protection eliminate ...

This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 &micro m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the sync ...
