格林帕克FAQ

格林帕克FAQ

92
Why should I consider GreenPAK for my next design?

GreenPAK的主要好处是:

1灵活性:因为GreenPAK是在几分钟内编程的,所以您的设计可以快速轻松地更改,以适应新的需求和纠正系统错误。过去需要板旋转的更改可以在几分钟内在桌面上完成。

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部件的选择取决于需要多少I/O、功能块(ACMP、ADC、DCMP/PWM)、精度和价格。

94
我必须在生产中对GreenPAK进行编程吗?

Dialog supports production programming of GreenPAK devices in quantities down to the order minimum quantity, which is 3K pieces (equal to the quantity on one reel).

95
Dialog需要我做什么才能在GreenPAK投入生产?

您需要提供一个已批准用于生产的代码文件。

96
如果Dialog帮助我为GreenPAK做设计,需要多长时间才能得到第一个版本?

通常很快。最短可达24小时,最长可达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。最快的速度是通过连接没有内部块(输入引脚->输出引脚)。下一个最快的是Input PIN->LUT->Output PIN。

98
我可以在输入引脚上施加高于Vdd的电压吗?

Yes, but not more than VDD + 0.3 V. Every IO pin is clamped by an ESD diode to 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
静态电流是如何定义的,它是如何如此之低?

The quiescent current is defined as the current for the design when all inputs and outputs are static, and oscillator and analog blocks are in operational mode if enabled in the design. Very low current consumption is made possible by GreenPAK's capability to dynamically turn on oscillator and analog blocks for the time during which they are required.

101
What is propagation delay time of GreenPAK?

这在很大程度上取决于设计因素:使用的模块、连接的数量、VDD、工作温度等等。有关更多详细信息,请参阅数据表中的“定时估计器”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在启动过程中将数据从NVM加载到SRAM寄存器,SRAM寄存器配置所有块和连接。

104
What type of NVM memory is onboard?

The NVM is one time programmable (OTP) memory using the OTP Fuse from TSMC's 0.18 μm 1.8 V / 5 V Logic process. Programming is done via hot electron injection generated by avalanche impact ionization in the bit cell.

105
如果部件是OTP,开发板如何模拟设计?

The chip has NVM memory that is used for storing data when it is turned off and is one-time programmable. After powering up the data is being copied to the register (buffer), from where it is used to configure the chip. In the emulation mode the NVM is not used, chip configuration is being directly written to the buffer. So, even the chip is one-time programmable, using of emulation mode practically does not have restrictions.

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

在物理上这是可能的,但编程部分需要施加高电压(7.5 V),以及特定的信号序列和引脚上的时钟。对话框不建议这样做。

107
每次部件通电时都会读取NVM,那么NVM在其使用寿命内可以可靠地执行多少个读取周期?

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
关于环境影响(温度、辐射等)对NVM可靠性和寿命的影响,有哪些数据?

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的区别是什么?

对话框继续提高产品的一部分雷电竞官网登录s philosophy. Based on customer feedback and the tremendous success of the product family, Dialog has added another GreenPAK2 version called Rev B with improved performance to the internal oscillator and analog blocks.

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
What are the HTS codes for GreenPAK parts?
  • 国际结算系统-8542.39.0000
  • 董事会-8452.31.0000
