STMicroelectronics (ST) unveiled the structured architecture of bridges and regulators (S.A.B.Re), an integrated circuit (IC) with a set of configurable and customizable analog functions for printer, fax and point-of-sale system applications.
The S.A.B.Re complements the ST structured processor enhanced architecture (SPEAr) family of customizable digital engines for printers, scanners and other embedded-control applications, extending configurability and customizability to the analog domain, according to ST.
The main components of the S.A.B.Re IC include:
Four configurable bridges that can function as switching regulators or power charge.
A variable-voltage buck switching regulator.
A switching regulator controller.
A linear regulator.
A multichannel configurable 9 b analog-to-digital (A/D) converter.
Two operational amplifiers.
A bidirectional serial interface
Several general-purpose input/outputs (I/Os).
The S.A.B.Re device integrates features that can be configured and customized, including motor drivers, regulators, an A/D converter, operational amplifiers and voltage comparators.
The flexibility enables customers to adapt the S.A.B.Re device to the specific needs of a particular application, according to ST.
Certain architectural changes can be programmed via the serial interface and/or general purpose input/outputs (I/Os), while more complex functions can be customized with metal layers implementing specific macro functions. According to ST, the metal customization does not modify any active part of the silicon, minimizing the risk of parasitic effects.
The S.A.B.Re IC was developed for motion and power-supply parts in printer applications. Standing out from existing motor drivers and switching regulators, the device functions as the master and manages the whole power section of the application with specific programmable PowerUp routines before the digital IC switches on.
ST said the S.A.B.Re can address any high-power, high-voltage analog and motor applications across the industrial segment.
Samples are available now, with volume production planned for 4Q 2007.
