In order to enable communication with the MIC74001 GUI, the Programming Board must be connected to the MIC7400/1 Evaluation Board (using J2) and the Evaluation Board must be connected to a PC via USB. To be recognized by the MIC7400/1 GUI, the on-board EEPROM must first be initialized (by reading any MIC7400/1 device). NOTICE In order to prevent conflict on the I2C bus, the Select switch must be moved to position 0 before connecting the MIC700/1 Evaluation Boards. DS50002593A-page 13 2017 Microchip Technology Inc. Installation and Operation On-board coin-cell power supply (CR2032) J2 Standard 2.54 mm male connector to MIC7400/1 Evaluation Board (ADM00811/2) J1 PIC(R) Microcontroller Programming Header; used to connect to the PICKit3 Micro USB power connector FIGURE 2-2: 2.4 MIC7400/1 Programming Board Bottom View - Connectors. USING THE MIC7400/1 PROGRAMMING BOARD 2.4.1 Powering and interfacing with the MIC7400/1 Programming Board The MIC7400/1 Programming Board can be connected to any I2C interface that has a MIC7400/1 connected. Great care must be taken when connecting to a complex I2C system so that the MIC7400/1 Programming Board is the only MASTER active, otherwise false readings and writings may occur due to a conflict on the I2C bus. After power is applied to the MIC7400/1 Programming Board and to the attached device, the MIC7400/1 Programming Board can be turned on by switching ON the Battery ON/OFF switch (while being powered by the coin cell) or by switching on the external power supply. 2.4.2 Modes of Operation The MIC7400/1 Programming Board software is structured around the Select rotary switch whose position determines the operating mode of the MIC7400/1 Programming Board and the functionality of the buttons and switches. There are eight possible modes of operation. They are determined by the position of the Select rotary switch, as described in Sections 2.4.2.1 through 2.4.2.4. 2.4.2.1 POSITION 0 In this position, the I2C bus is active only for a few milliseconds while the welcome screen ("MICROCHIP MIC7400/1") is displayed; after a few milliseconds, the activity on the I2C bus stops. 2017 Microchip Technology Inc. DS50002593A-page 14 MIC7400/1 Programming Board User's Guide Note: The integrated MCP2221 on the MIC7400/1 Evaluation Board can only be used while the MIC7400/1 Programming Board is in this mode, so there is no conflict between the microcontroller and the MCP2221. While using the MCP2221 (using the GUI to program the on-board EEPROM), pressing the READ or WRITE buttons is not advised. In order to read the on-board EEPROM, the device address in the MIC7400/1 GUI must be changed to 0b1010000x (50h). When not using the MIC2221 integrated on the MIC7400/1 Evaluation Board, the READ button can be used to read the content of the MIC7400/1 internal EEPROM and copy it to the on-board EEPROM. The PG 1-6 LEDs will light up in sequence to signal the start of the reading process and a "Reading..." message will be displayed on the LCD screen. If the action is successful, a message ("DONE") will briefly be displayed on the screen and the I2C activity will stop. When not using the MIC2221 integrated on the MIC7400/1 Evaluation Board, the WRITE button can be used to write the content of the on-board EEPROM to the MIC7400/1 internal EEPROM. The PG 1-6 LEDs will light up in sequence to signal the start of the writing process and a "Writing..." message will appear on the LCD screen. If the action is successful, the message "DONE" will briefly be displayed on the screen and the I2C activity will stop. If a read/write action cannot be started, due to an error on the I2C bus or to the MIC7400/1 not responding, an "ERROR" message will appear on the screen and all PG1-6 LEDs will flash five times, after which the I2C bus activity stops. If a read/write action is started but cannot be completed, an "Action not comp." message will be displayed on the screen and all PG 1 - 6 LEDs will flash five times, after which the I2C bus activity stops. 2.4.2.2 POSITIONS 1-6 In this mode, the Voltage and Current potentiometers can be used to set the voltage and the current limit of the selected regulator. Mode selection is done by means of the SEL switch, which enables writing to either the Standby (STBY) or Normal (NORM) mode of operation. Using the Read button, the current mode of operation for the attached MIC7400/1 can be changed. After the desired voltage and current limit have been selected, press the WRITE button to write the new values to the MIC7400/1 temporary register and to the on-board EEPROM. These values will not be saved directly into the internal EEPROM of the MIC7400/1 and can be canceled by performing a power-down/power-up sequence. To save the newly-input values into the MIC7400/1 internal EEPROM, the Select switch must be changed to position 0 and the WRITE button must be pressed. 2.4.2.3 POSITION 7 This mode is used to assign each selected converter to the selected sequence and the delay between sequences. When the SEL switch is set to NORM: - the channel (buck or boost) can be selected with the Voltage potentiometer - the sequence can be selected with the Current potentiometer Once the desired channel and sequence have been selected, press the WRITE button to send the new configuration to the MIC7400/1 and to the on-board EEPROM. Flashing the PG LEDs 2 times confirms that the write action has been completed successfully. DS50002593A-page 15 2017 Microchip Technology Inc. Installation and Operation Switching SEL to STBY selects the sequence delay from 0 ms to 7 ms, by using the Current potentiometer. The configuration can be saved by pressing the WRITE button. Flashing the PG LEDs 2 times confirms that the write action has been completed successfully. 2.4.2.4 PG 1-6 (Power-Good) Status LEDs The MIC7400/1 Programming Board is equipped with six green LEDs used to indicate the Power-Good status of the MIC7400/1 converters. These LEDs use the internal Power Good Register (00h) to determine the status of all six converters and work only when the board is in mode 1-7 (in mode 0 there is no activity on the I2C bus). 2.5 TYPICAL USAGE EXAMPLES 2.5.1 Configure Device Settings and Upload Them to the MIC7400/1 EEPROM Configuring the device settings by means of the Voltage and Current potentiometers is the most basic functionality of the MIC7400/1 Programming Board. Next are the steps necessary for configuring: * connect the MIC7400/1 Programming Board to the desired MIC7400/1 via J2 connector (refer to Figure 2-2) * power the MIC7400/1 Programming Board and the desired MIC7400/1 * bring the Select switch to position 0 * press the READ button to copy the MIC7400/1 registers to the MIC7400/1 Programming Board's EEPROM. The successful completion of the action is confirmed by a "DONE" message displayed on the screen (refer to Section 2.4.2.1 "Position 0"). This action is necessary in order to maintain the register values that are not modified by the board * choose the desired channel by rotating the Select switch to a position that ranges from 1 to 6 * with the desired channel selected, choose the mode of operation (Stand-by or Normal) to which the configuration should be saved, by using the SEL switch * use the Voltage and Current potentiometers to select the desired output voltage and current limit, respectively * press the WRITE button to save the new configuration to the MIC7400/1 temporary memory and the on-board EEPROM. * to copy the on-board EEPROM into the permanent MIC7400/1 internal EEPROM: - the Select switch must be changed to position 0 - the WRITE button must be pressed At any point, if the MIC7400/1 is powered down or reset, all settings in the temporary memory will be lost, but these will still be present in the on-board EEPROM, so that a write cycle to MIC7400/1 will restore and save them. Note that regardless if the MIC7400/1 is connected to the MIC7400/1 Programming Board or not, the on-board EEPROM will still be written to. 2.5.2 Copy the Settings from the MIC7400/1 GUI to the MIC7400/1 Programming Board, Then Upload Them to Any MIC7400/1 EEPROM If the MIC7400/1 configurations have already been done and saved using the MIC7400/1 GUI, the user can save all the registers to the MIC7400/1 Programming Board's EEPROM and then program other MIC7400/1 devices without the help of the MIC7400/1 GUI. 2017 Microchip Technology Inc.

See Section 2.4.2.1 "Position 0" * disconnect the MIC7400/1 Programming Board and reconnect it to the MIC7400/1 that the configuration needs to be transferred to * power both the successive MIC7400/1 and the MIC7400/1 Programming Board * make sure the board Select switch is in position 0 * press the WRITE button; a "DONE" message confirms that the action was successfully completed. See Section 2.4.2.1 "Position 0" 2.5.3.2 MIC7400/1 PROGRAMMING BOARD EEPROM TO MIC7400/1 GUI To export the settings from the MIC7400/1 Programming Board to the MIC7400/1 GUI, the following sequence must be applied: * connect any MIC7400/1 Evaluation Board to the MIC7400/1 Programming Board using the standard 2.54 mm female header situated on the boards top left corner (J2) * bring the Select switch to position 0 * connect the MIC7400/1 Evaluation Board to the GUI using a USB cable * power the MIC7400/1 Programming Board and start the MIC7400/1 GUI * click the ScanAddr button. In the Addr box, two devices should be detected: the MIC7400/1 PMIC (address 0x30, if powered) and the MIC7400/1 Programming Board on-board EEPROM (address: 0x50). Select the 0x50 address and press Connect button. * go to the OPERATION section tab and click the ReadAll button to read the configurations 2.5.4 Setting the Start-Up Sequence and Saving It to the MIC7400/1 EEPROM This feature of the MIC7400/1 Programming Board allows the MIC7400/1 regulators to start in a predefined sequence and with a preset delay between them, necessary for the new generation of microprocessors and FPGAs. These are the steps necessary for configuring the start-up sequence: * * * * * connect the MIC7400/1 Programming Board to a MIC7400/1 power both the MIC7400/1 Programming Board and the device connected to it bring the Select switch to position 7 set the SEL switch to NORM use the Voltage potentiometer to select the desired channel (channels 1-5 for buck converters, and channel 6 for boost converter) and the Current potentiometer for selecting the desired place in the start-up sequence * press the WRITE button to transfer the new data to the MIC7400/1 volatile memory and to the on-board EEPROM * after the desired sequence has been set, move the SEL switch to STBY * set the sequence delay by using the Current potentiometer. The sequence delay can be set between 0 and 7 ms. The display will show the newly set delay together with the previous delay set in the MIC7400/1 2017 Microchip Technology Inc. DS50002593A-page 18 MIC7400/1 Programming Board User's Guide * press the WRITE button to memorize the new delay * to make the new configuration permanent, rotate the Select switch to position 0 and press the WRITE button Note: DS50002593A-page 19 Note that pressing the WRITE button will permanently save the on-board EEPROM into the MIC7400/1 internal EEPROM. 2017 Microchip Technology Inc.
