Power SoCs extend to automotive
temperatures
AMI Semiconductor is extending the maximum operating temperature of its SmartPower high-voltage system-on-chip mixed-signal IC technology to 200C.
AMI Semiconductor is extending the maximum operating temperature of its SmartPower high-voltage system-on-chip (SoC) mixed-signal IC technology to 200C AMI Semiconductor's SmartPower mixed-signal semiconductor technologies allow designers to integrate complex digital and precision analogue circuitry, embedded microprocessors, nonvolatile memory and high-voltage functionality into a single IC

Clock generators for embedded communications
AMI Semiconductor (AMIS) has expanded its clock generator product line with a broad family of low-cost 1- and 2-phase-lock loop (PLL) clock ICs.
The result is a technology that is ideal for a variety of applications such as sensor interfaces, transceivers and actuator and motor drivers.
Until now the maximum rated operating temperature for such devices had been 150C.
Raising this maximum to 200C, while maintaining reliability levels, enables highly integrated mixed-signal ICs to be created for existing and emerging automotive and industrial designs and other applications where very high ambient temperatures have previously precluded their use.

Extended-temperature interface for AS-i bus
AMI Semiconductor (AMIS) has expanded its family of reprogrammable interface ICs certified for Actuator Sensor-interface (AS-i) bus applications by launching an extended temperature device.
The new technology will be important to automotive designers under pressure to increase the sophistication of onboard electronics while saving space, improving reliability, and bringing monitoring and control electronics physically closer to the target application.
As a result, applications such as drive-by-wire, monitoring and control of fuel consumption, exhaust emissions, and temperature measurement mean that many electronic applications are expected to operate in temperatures exceeding 175C.
"Whether it's placing an IC in the engine oil to measure temperature, close to the bulbs in a headlamp unit or in the exhaust to monitor emissions, there is a clear trend of localising electronic components to the application that they monitor or control", said Bob Klosterboer, Senior Vice President of Integrated Mixed-Signal Products at AMIS.
"In many cases this means very high temperature operation".
"At the same time, pressure to reduce component count is fuelling demand for integrated designs".
"By increasing the maximum operating temperature of our SmartPower mixed-signal technologies, we provide the designer with a route to cost-effectively create compact and reliable SoC solutions that address all of these requirements".
AMIS is currently qualifying its I2T100 and I3T50 mixed-signal semiconductor technology to the new 200C maximum temperature.
Also the company's I3T80 mixed-signal technology will be qualified shortly.
These technologies allow for the creation of mixed-signal SoCs capable of operating at up to 100V with currents up to 3A.
High precision analogue circuitry can be combined with embedded ARM or 8051 processors and a nonvolatile memory like OTP.
A comprehensive family of IP blocks including PLLs, USB interfaces, bus protocol controllers, and controllers for CAN and LIN connectivity simplify and speed the implementation of AMIS SmartPower SoCs.
