The primary benefits for GreenPAK are:
1. Flexibility: because GreenPAK is programmed in minutes, your design can be quickly and easily changed to adapt to new requirements and correct system bugs. Changes that in the past would require a board spin can be made in minutes on your desktop.
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.
The choice of the GreenPAK part depends on how many I/Os are required, functional blocks (ACMP, ADC, DCMP/PWM), accuracy and the price.
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).
You need to provide a code file that you have approved for production.
It is usually very quick. It can be as short as 24 hours, to as long as 2 weeks.
The maximum data rate is dependent on which internal blocks the signal will travel through. The fastest rate is through connection with no internal blocks (Input PIN -> Output PIN). The next fastest is Input PIN -> LUT -> Output PIN.
Yes, but not more than VDD + 0.3 V. Every IO pin is clamped by an ESD diode to VDD.
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.
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.
This greatly depends on the design factors: blocks used, how many connections were made, VDD, operating temperature and so on. Please refer to the "Timing Estimator" section in the datasheet for more detailed information.
All PINs are in High Impedance state at power on and during the power on sequence.
GreenPAK loads data from the NVM to an SRAM register during the start-up process, which configures all blocks and connections.
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.
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.
Physically this is possible, but programming the part requires applying high voltages (7.5 V), as well as specific signal sequences and clocking on the pins. Dialog does not recommend to do this.
NVM testing is performed as part of the device qualification 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.
Temperature effects have been studied as outlined above. No MIL-STD_883 M1032 radiation testing has been conducted.
Dialog continues to improve products as part of its 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.
GreenPAK products are used on commercial/consumer application only and are not on the commerce control list, therefore are designated as EAR99.
