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.
1.2 Chip orientation

Pin “1” of the chip shall be located in the lower left corner of the open socket. This is marked with a “1” on the
PCB.

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.

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.
FUSE PRGM
Here the actual fuse procedure is performed. This takes at least ~10.5 ms. The end of the procedure signalized
by setting the Iout pad to high state.
WAIT RXD
The FUSE programming is done, this is signalized by setting Iout to HIGH state. After detecting this state the RXD
should be set to HIGH within 100 ms to procced with the next state, the Iout is set to LOW.
FUSE CHECK
In this state the fuses will be read out and compared with the received UART byte. This step takes ~100 µs.

DONE
If the compared data it correct the Iout is set to HIGH if not this will say in LOW in this state. Remark that the
power down/up step is required to return to the normal operation after the whole efuse burning procedure is
performed.
The detailed fusing timing is shown in the figure below. Remark the 100ms timing after the FUSE PRGM state.
