ST70138 Datasheet PDF - STMicroelectronics

DESCRIPTION
Unicorn II is an evolution of the field-proven and mass deployed Unicorn modem that dramatically lowers the overall system cost when designing and producing a USB ADSL modem. The Unicorn II chipset is designed using cost effective CMOS technology, further integrating external components which leads to even lower E-BOM costs, reduced component count and lower PCB complexity; All of this while increasing overall performance. Its proven controller-less and SDRAM less architecture is highly competitive and well suited in today's cost focused modem market.
