GreenPak常见问题解答

GreenPak常见问题解答

92
Why should I consider GreenPAK for my next design?

GreenPak的主要优点是:

1.灵活性:因为GreenPak在几分钟内编程,您的设计可以快速轻松地改变以适应新的要求和正确的系统错误。过去的变化需要在桌面上几分钟内需要在几分钟内进行板旋转。

2. Low Power: GreenPAK designs typically run at a few microamps in standby, and typically use less than 100 milliamps average in active mode. The architecture of each GreenPAK device is optimized to give you maximum control over power consumption.

3. Small Size: It is common that the circuitry replaced by GreenPAK is 5 – 10 times larger board area than the GreenPAK.

93
How should I pick the part that works best for my design?

GreenPak部分的选择取决于需要多少I / O,功能块(ACMP,ADC,DCMP / PWM),准确性和价格。

94
我必须在生产中编程GreenPak吗?

对话框支持以批量为单位的GreenPak设备的生产编程,为订单最小数量,即3k件(等于一个卷轴上的数量)。

95
对话是什么需要我在GreenPak上进入生产?

您需要提供您已批准生产的代码文件。

96
如果对话框有助于我为GreenPak进行设计,获得第一个版本需要多长时间?

它通常非常快。它可以短至24小时,至长达2周。

97
GreenPak的最大数据速率是多少?

最大数据速率取决于信号将通过的内部块。最快的速率是通过无内部块的连接(输入引脚 - >输出引脚)。下一个最快的输入引脚 - > LUT - >输出引脚。

98
我可以在输入引脚上施加高于VDD的电压吗?

是的,但不超过VDD + 0.3 V.每个IO引脚由ESD二极管钳位到VDD。

99
What is the input impedance seen at the analog pin?

It depends on the analog block used and its configuration (buffer, low bandwidth, gain and so on). The ACMP input is in range of GOhms for gain slection 1x. However, allow for at least 0.1 uA. due to leakage from ESD protection structure.

100.
如何定义静态电流,它如何如此低?

当所有输入和输出都是静态时,静态电流被定义为设计的电流,如果在设计中启用,振荡器和模拟块处于操作模式。GreenPak的能力非常低电流消耗,以动态打开所需时间的振荡器和模拟块。

101.
What is propagation delay time of GreenPAK?

这大大取决于设计因素:使用的块,进行了多少连接,VDD,工作温度等。有关更多详细信息,请参阅数据表中的“时序估算器”部分。

102.
What is the state of the pins at power on and during the power on sequence?

All PINs are in High Impedance state at power on and during the power on sequence.

103.
How does the part configure itself at start-up?

GreenPak在启动过程中将来自NVM的数据加载到SRAM寄存器,这配置了所有块和连接。

104.
船上的NVM内存是什么类型的?

NVM是一种时间可编程(OTP)内存,使用TSMC的0.18μm1.8 V / 5 V逻辑过程。通过钻头电池中的雪崩冲击电离产生的热电子注射来完成编程。

105.
如果部分是OTP,DEV板如何模拟设计?

该芯片具有NVM内存,用于在关闭时存储数据,并且是一次性可编程。向上加电后,数据被复制到寄存器(缓冲区),从它用于配置芯片的位置。在仿真模式下,未使用NVM,芯片配置直接写入缓冲区。因此,即使是芯片是一次性可编程,使用仿真模式实际上没有限制。

106.
Can I solder blank parts on my board and then program the NVM?

在物理上这是可能的,但是编程零件需要施加高电压(7.5 V),以及特定的信号序列和针对引脚时钟。对话框不建议执行此操作。

107.
每次零件向上读取NVM,所以NVM可以在其寿命中可靠地执行多少读周期?

NVM测试执行必要的设备lification and quarterly thereafter as part of the ongoing reliability monitor. The testing is performed in accordance with JESD22-A103 condition B, 1000 hours @ +150°C. To date 1,815,000 device hours have been accumulated with no failures. Assuming an in-use temperature of +25°C and a 90% confidence interval there would be less than 1 failure for every 1,000,000,000 device hours.

108.
关于NVM可靠性和寿命的环境影响(温度,辐射等)有什么样的数据?

Temperature effects have been studied as outlined above. No MIL-STD_883 M1032 radiation testing has been conducted.

109.
GreenPak SLG46400 Rev A和Rev B Silicon之间有什么区别?

对话框继续提高产品作为其哲学的一部分。亚博电竞菠菜根据客户的反馈和产品系列的巨大成功,对话框已添加另一个称为Rev B的GreenPak2版本,并在内部振荡器和模拟块的性能提高。

118.
What is the Export Control Classification Number (ECCN) for GreenPAK parts?

格林帕克products are used on commercial/consumer application only and are not on the commerce control list, therefore are designated as EAR99.

119.
GreenPak零件的HTS代码是什么?
  • ICS - 8542.39.0000
  • 董事会 - 8452.31.0000
