The AT73C203 power management standard product for 3G wireless platforms is manufactured on Atmel's low-cost mainstream CMOS process to provide an integrated solution for portable and handheld applications based on microprocessors that require 'smart' power management functions. Examples are: 3G phones, PDAs, Palmtop computers, point-of-sales terminals, 3G modems and others.
The AT73C203 features the set of power supplies and interfacing systems that is used in a device based on Intel XScale processors. Three sets of step-down switching converters supply application cores, memories and analog blocks, with each up to 1,2 A. Output voltage ranges are 0,87 to 1,2 V, 1,0 to 1,80 V and 1,70 to 2,60 V with dynamic adjustment in order to optimise current consumption inside the application core. An additional 520 mA step-up/down switching converter with output voltage range 3,0 to 3,4 V supplies RF components and peripherals allowing the system to benefit from very low Li-Ion battery voltage, down to 2,8 V. The device includes an integrated dual battery charger designed to supply both internal and external batteries.
The AT73C203 also provides the full voltage supply range (1,8 or 3,0 V), the level shifters for a SIM (subscriber identity module) interface compatible with GSM11.12 & 11.18 and the ISO7816 UART compatible interface macro.
Atmel offers the AT73C203 in a 9 x 9 mm, 100-ball ultra-thin BGA. It is available on a reference design board or as engineering samples.
