I. KEY Back-light Illumination
• KEYPAD Back-light Scheme.
• There are 12 Deep Blue LEDs in Main Board for Keypad Backlight.
• Keypad Back-light is driven by ‘LEDB’ line from IOTA .
J. SIM
• SIM Interface
The SIM Card digital interface in ABB insures the translation of logic levels between DBB and SIM
Card, for the transmission of 3 different signals:
• A clock derived from a clock elaborated in DBB, to the SIM-Card (DBBSCK
→
SIM_CLK)
• A reset signal from DBB to the SIM Card (DBBSRST
→
SIM_RST),
• A serial data from DBB to the SIM Card (DBBSIO
→
SIM_IO) and vice-versa.
The SIM card interface can be programmed to drive a 1.8V or 3V SIM Card.
