7 Pinning information

7.1 Pinning

The pinning for the MF1S70yyX/V1DAx is shown as an example in Figure 3 for the

MOA4 contactless module. For the contactless module MOA8, the pinning is analogous

and not explicitly shown.

8 Functional description

8.1 Block description

The MF1S70yyX/V1 chip consists of a 4 kB EEPROM, RF interface and Digital Control

Unit. Energy and data are transferred via an antenna consisting of a coil with a small

number of turns which is directly connected to the MF1S70yyX/V1. No further external

components are necessary. Refer to the document Ref. 1 for details on antenna design.

• RF interface:

– Modulator/demodulator

– Rectifier

– Clock regenerator

– Power-On Reset (POR)

– Voltage regulator

• Anticollision: Multiple cards in the field may be selected and managed in sequence

• Authentication: Preceding any memory operation the authentication procedure ensures

that access to a block is only possible via the two keys specified for each block
