1.1 Introduction

The COOLDIM_PRG_BOARD is used to set fuses inside CDM10V chip. It is supplied from a USB power supply (5 V / 1 A) or could also be connected to a USB port of the PC. User will be guided through the burning process by the microcontroller firmware. If an error occur during handling user will be advised by firmware how to proceed. When no button is pressed during 5 minutes the display is switched off automatically and the LED below the display is flashing once per second, pressing any button will switch on the display again.

1.3 Control buttons

ON/OFF

Check if chip is applied in correct position and turn supply voltage on or off. When supply is turned on all 4 parameters are measured and shown in display. If one parameter could not be measured a contact fail is expected supply is turned off and the user is informed to check the socket. If none of the parameter could be measured user is informed that it is expected that socket is empty and supply is turned off. Only if all parameter could be measured correctly (+/- 10%) supply stays on and allows the use to proceed.

Toggle

Toggle screen to show either chip settings or board settings. To burn the board settings user has to switch to board settings view.

Burn

Start the fuse burning procedure. Fuse burning will only be started if:

1. The board settings differ from chip settings

2. Setting one (or several) bit to “1” If these conditions are not fulfilled, burn procedure is aborted.

1.4 Switches

The switches are used to set the state of the fuses. Please note: user is only able to set a fuse bit from “0” to “1”. If a bit is already set to “1” it could be not reversed and burn fuse will be aborted. The decoding of the switches

is printed on the board and will be shown in board settings view on the display.

2.1 UART configuration

The serial port (9600 Baud, 1 stop bit, no parity) enables a onetime reconfiguration of parameters for device function. The reserved CMD bit has to be set to HIGH. After this bit the 7 programming has to be sent in the order shown in the picture below.

Figure 4 UART data frame format

The figure below shows the minimal fuse programming circuit diagram. The LED is optional and can be used to signalize the correct fusing procedure.

2.3 Fusing procedure

To ensure the correct efuse burning automatic programming and checking procedure is implemented. Remark that fusing can be done one time only per device.

Figure 6 Fusing procedure

IDLE

The device is awaiting the correct UART frame. After correct frame is received (CMD bit is set to HIGH) the fuse programming procedure is started.

out

In this state the fuses will be read out and compared with the received UART byte. This step takes ~100 µs.
