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.

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.

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.
