The Promira  Serial Platform, together with the SPI Active Level 1 and SPI Active Level 2 Applications make an excellent tool for programming low voltage Dual SPI Flash devices. You can use the Promira platform with the Control Center Serial Software, and see how easy it is to provide up to 200 mA at the selected voltage level, and program and verify your target SPI device.

Reap the benefits of  the Promira platform and the SPI Active - Level 2 Application:

• Program EEPROM, Flash, or other SPI memory, in Single or Dual I/O mode
• Up to 200 mA of power to embedded project, at voltage levels from 0.9 V - 3.45 V
• SPI Master speed up to 40 MHz
• SPI Slave speeds up to 20 MHz
• 1 default response plus 8 unique slave responses of up to 256 bytes/response
• Single slave response of up to 256 bytes
• Use up to 12 GPIOs
• Up to 3 Slave Selects (configurable, shared with GPIO)
• Software configurable Slave Select (SS) polarity in master mode

The Control Center Serial Software is an easy to use GUI that allows you to easily interface with your slave device, It includes the ability to program in batch mode, which makes running repetitive commands significantly easier.  The batch scripts can be saved as XML files that you can use as-is or modify as needed.

Following is a summary of how to set up and then program your SPI Dual Flash device:

1. Connect the Promira platform to the Control Center Serial Software on your lab computer
2. Connect the Promira platform to the target device
3. Configure the Promira platform for Multi I/O SPI
4. Configure the desired voltage level for powering the target device
5. Configure the desired bitrate
6. Configure the Promira platform for Dual SPI Mode
7. Initialize the target device and read the device ID

Figure 3 below shows an example of this configuration in the Transaction Log:

Figure 2: Configure Promira for Dual SPI Mode

1. Initialize the target device and erase the data sector
2. Write data to the device
3. Read and verify the data from the device
