■■
■DESCRIPTION
MB3891 is intended to be used in future GSM-phones, Dual Band phones and Dual Mode phones. It contains all
the necessary functions to support all Digital, Analog and RF blocks in these phones. A Charge-pump including
a Logic Level Translation circuit is built in to support SIM-card (SmartCard) of both 3 and 5 Volt technology. The
circuit contains a charger for a rechargeable Lithium coin cell of a Real Time Clock.
A complex control circuit is built in to generate main reset and to turn on and off the different LDO’s.
■
■■

■ABSOLUTE MAXIMUM RATINGS
* : The packages are mounted on the dual-sided epoxy board(10 cm ×10 cm)
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
■
■■
■RECOMMENDED OPERATING CONDITIONS
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
