First release- HL5311 ToyID e-Dice

The final version of HL5311 has eight operational modes, can easily be designed for 7-choose-1, 6-choose-1, 5-choose-1, 4-choose-1, 3-choose-1 and 2-choose-1 dice. This operation mode is selected by MS2, MS1, and MS0. Especially, HL5311 is supported to Multi-TAG operation. You can put more than 2 different dices at the same time and this combination result will also send to reader.

The Operation of e-Dice
When setting done the operation mode of HL5311, you can assign its transmission order chosen pins selected by A2-A0. That is means you could put up to 8 different e-Dices in the same antenna field. Each e-Dice in antenna field would send the “000” from the 3 most significant bits (A11-A9) of its ID, then start rolling. When rolling is done, the selected number would also be sent out from A11-A9.

For example, you want to make a “5-choose-1” e-Dice and its transmission order is 2. First set the [MS2, MS1, MS0] pins to [1, 0, 0], that is wiring these pins to VDD("1") or GND("0"). Secondly set the [A2, A1, A0] pins to [0, 1, 0]. Then set the [A8-A4] to its item code(0~31; give 31 for this e-Dice). A3 is default set “0” internal of HL5311.

When put this e-Dice in Reader’s antenna field, it would send 12-bit ID as [0, 0, 0, 1, 1, 1, 1, 1, 0, 0, 0, 0] in the beginning. Then e-Dice starts rolling, the LED outputs LO1-LO5 drive low in turn by descending or ascending. When rolling done, if “3” was selected and HL5311 would send [0, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0] several times.
