Technology

Our hardware expertise can provide you with a full range of services including functional specifications and requirement documentation, schematics, layout, prototype manufacturing and testing. At the low end, we have designed embedded control systems that employ 8 bit micro-controllers and system interface control logic either in discrete logic or CPLD's / FPGAs

We are the third party developers for Freescale Semiconductors

At higher end, the designs have included 8/16/32 bit microprocessors from almost all the major vendors; Static Ram, Flash memory, communication interface devices, display controllers. Many designs also incorporate multiple controllers with necessary handshaking & using common resources such as memories etc. Some products are designed using DSP's from TI & Analog Devices for high speed analog signal processing, Math applications & algorithms.

The control logic for each design has been implemented utilizing an appropriate technology, such as PAL's, CPLDs or FPGA's. We can offer Altera, Actel, Xilinx and Quick-Logic FPGA based designs, including converting discrete logic circuits into FPGAs.

Our design expertise span around mixed signals using extensive analog circuits to process high frequency, low level signals & interfacing the same using ADC's up to 16 bits resolutions. The power supplies required for these designs are also designed in-house. Designs are implemented using multiplayer boards & using SMT & designed to meet various EMI/EMC requirements for high speed mixed signal circuits.
