GreenPAK design software and development tools to create and program custom circuits in minutes

Dialog GreenPAKTM is a cost-effective, non-volatile memory (NVM) programmable device that enables innovative enterprises to integrate numerous system functions while minimizing component count, shrinking size and reducing power consumption. Using Dialog's GreenPAK design software and GreenPAK development tools, design engineers can create and program custom circuits in minutes.

GreenPAK is great for:

Instead of the commonly used mixed-signal standard products, it is often possible to replace the functions of several chips at the same time.

Provides reliable hardware security and reset functionality for software-encoded devices such as SoCs and microcontrollers.

Add a variety of different features.

Overcome the last minute design challenges/issues.

GreenPAK compares the advantages of discrete design

Smaller PCB component form factor – plastic package as small as 1.0 x 1.2 mm.

Fewer component count / lower cost – A typical GreenPAK implementation can reduce 10 to 30 components.

Higher reliability – fewer PCB connection points increase reliability.

Faster design – Develop and program devices on your desk in just a few minutes. Respond quickly to design modification requirements and increase productivity during the design and prototyping phases.

Lower power consumption – saves energy by eliminating discrete resistors in voltage dividers, pull-up resistors, and pull-down resistors, and replacing them with low-power, integrated components. Use the sleep function to further reduce power consumption.

Design Security – By disabling readback of non-volatile memory (NVM) configurations, design details are hard to find, greatly increasing the difficulty of reverse engineering.

Tested solution – Every GreenPAK IC is tested and the discrete circuit cannot be tested before the final board level test.

We have compiled and answered some of the common questions and green puzzles in GreenPAK to help you learn more about how to use GreenPAK technology.

Why should I consider GreenPAK in my future design?

The main advantages of GreenPAK include:

Flexible : Programming takes just a few minutes, making it quick and easy to modify your design to meet new requirements or fix system defects. In the past, it was necessary to re-create the entire board to make product changes, but now it only takes a few minutes at the desk.

Low power consumption : The GreenPAK design typically consumes only a few microamps in standby mode and consumes less than 100 milliamps on average when active. Each GreenPAK device architecture is optimized to give you maximum control over power consumption.

Small size : Circuits replaced by GreenPAK typically have a 5-10 times larger footprint than GreenPAK.

How to choose the component that best suits my design?

The choice of GreenPAK components depends on how many I/Os, function blocks (ACMP, ADC, DCMP/PWM), accuracy and price are required.

Do I need to program GreenPAK in production?

Dialog provides production programming support for GreenPAK devices for users who meet the minimum order quantity (3,000, equivalent to one reel).

What should Dialog need for me to get GreenPAK into mass production?

You will need to provide a code file that has been approved by your production.

If Dialog assists me in designing GreenPAK, how long will I get the first version of the design?

Generally speaking very quickly. Fast 24 hours, up to 2 weeks.

What is the maximum data rate of GreenPAK?

The maximum data rate depends on which internal functional units the signal passes through. The fastest rate is through a connection without an internal functional unit (input pin -> output pin). The second fastest is the input pin -> LUT -> output pin.

Can I apply a voltage higher than Vdd on the input pin?

Yes, but not higher than VDD + 0.3 V. Each IO pin is clamped to VDD by an ESD diode.

What is the input impedance on the analog pin?

This depends on the analog block used and its configuration (buffer, low bandwidth, gain, etc.). When the gain is selected to be 1x, the ACMP input is in the GOhms range. Due to the presence of the ESD protection structure, it is allowed to increase the leakage current by at least 0.1 uA.

How to define quiescent current, how does it do so low?

The quiescent current is defined as the current in which all input and output circuits in the design are static, while the oscillator and analog blocks are only enabled in the run mode. Very low current consumption is achieved by GreenPAK's ability to enable the oscillator and analog block to be dynamically turned on only when needed.

How long is the transmission delay of GreenPAK?

This depends a lot on the design factors: the module used, how many connection points, VDD, operating temperature, and so on. Please refer to the “Time Series Estimation” section of the data sheet for more details.

What is the state of the pin at power-on and the state during the power-up sequence?

All pins are in a high impedance state during power-up and during power-up sequencing.

How do components configure themselves at startup?

During startup, GreenPAK reads data from the NVM into an SRAM register that configures all modules and connections.

What type of NVM memory is used on the board?

The NVM is a one-time programmable (OTP) memory that uses OTP fuses from TSMC's 0.18 μm 1.8 V / 5 V Logic process. Programming is accomplished by hot electron injection by avalanche collision ionization in the memory cell.

If the component is one-time programmable (OTP), how can the development board simulate the design?

The chip has NVM memory for storing data when power is lost and can only be programmed once. After power-on, the data is copied to registers (buffers), which are configured by the data in the buffer. In emulation mode, NVM is not used and the chip configuration is written directly into the buffer. So, although the chip is one-time programmable, there is virtually no limit to the use of emulation mode.

Can I solder some blank components on the board and then program the NVM?

Physically it is ok, but programming a component requires a high voltage (7.5V) and requires a special signal sequence and clock to be input through the pin. Dialog does not recommend this.

Each time the component is started, the NVM will be read. How many times can the NVM be reliably read during its lifetime?

We tested the NVM as part of the device qualification test and then tested it once a quarter as part of the daily reliability test. The test was carried out in accordance with JESD22-A103 Condition B, 1000 hours @ +150 °C. So far, we have performed 1,815,000 hours of testing for multiple devices, with no failures. Assuming an operating temperature of +25 ° C and a confidence interval of 90%, the probability of failure is less than once every 1 billion device hours.

What are the environmental factors (temperature, radiation, etc.) that affect the reliability and longevity of NVM?

The effect of temperature has been studied and illustrated in the above tests. So far we have not tested the MIL-STD_883 M1032 radiation.

What is the difference between GreenPAK SLG46400 Rev A and Rev B silicon?

Dialog follows the business philosophy of continuous improvement products. Based on customer feedback and the success of the product line, Dialog added another version of GreenPAK2 called Rev B, which further enhances the performance of the internal oscillator and analog blocks.

What is the Export Control Classification Number (ECCN) for GreenPAK components?

GreenPAK products are only used in commercial/consumer applications and are not on the commercial control list, so they are labeled EAR99.

What is the HTS code for the GreenPAK component?

The IC code is - 8542.39.0000 board code is - 8452.31.0000

How to read the mark on the IC package?

Please refer to the product data sheet for the definition of the package top marking system.
