SIM Flex
Introduction
The purpose of the SIM–flex is basically to connect ancillary parts to the
CMT. It has no active electronics and the main parts are the audio
components, mic, low profile buzzer and speaker plus a SIM–connector.

Functional Description
Main Components
Audio components
The flex has three audio components: microphone, earphone and buzzer.
Buzzer, mic and earphone are wired directly to flex connector without any
extra components. Microphone has one capasitor that works as a RF filter.
Connectors
There is a custom design SIM Connector and flex connector shaped area
in the flex.
Mecanical components
There is MIC Boot and EMC–tape for earpiece.
SIM interface
The SIM interface is the electrical interface between the smart card used
in the GSM and PCN applications and the MCU via the ASIC. Four signals
are used between the SIM card and the ASIC:
SIMDATA,
SIMCLK,
SIMRESET
VSIM.
Serial data is transferred between the card and the ASIC, the clock
frequency is 3.25 MHz. When there is no data transfer between the SIM
card and the CMT the clock can be reduced to 1.625 MHz. Some cards
allow to stop the clock in that mode. The ASIC also generates the reset for
the card and the supply voltage VSIM.
