MICRODUL Semiconductors

About Microdul

Microdul develops and produce customized microelectronic components, since 1970. As an engineering based company, it provide system solutions in microelectronic form.

Microdul have a long lasting experience in ASIC-design and customized packaging. It provides Micro-electronic solutions for your system requirements. Microdul is your partner for customized microelectronics.

Microdul and ni2designs

Microdul has appointed ni2designs as their channel partner for Indian region. ni2designs would provide an easy path to access fabrication and design services of Microdul.

ni2designs would help its customers to boost their design cycles with package of CATENA LAYTOOLS and MD300/MD500 arrays, which would be fastest package to design your own Mix-Signal ICs.

At the same point of time, ni2designs would also provide support to Microdul customers for its MD family of arrays.

Being as channel partners ni2designs will also promote design services offered by Microdul in the field of Mix-signal design, power electronics, RF circuits, and low power designs.

ASIC Technologies

We are experienced specialists in the design of mixed signal circuits on a semicustom-basis. If your application involves the acquisition, conditioning and processing of various analog signals we work together with you to find an efficient, intelligent solution. From your product idea, through the development of a circuit concept and the chip design to the delivery of fully tested and quality-guaranteed production quantities we deliver you a successful product. Contrary to what has become standard in the development of purely digital circuits using standard cells, the development of analog circuits requires the special know-how of experts. We have that team. Thanks to our semicustom design philosophy, we are cost-effective and fast during the development phase.

MD Family - CMOS Semicustom Arrays for Mixed Signal Circuits:

A semicustom circuit consists of many prefabricated active switching elements usually arranged in regular arrays on a base chip. To create a desired functionality, the interconnection between these elements is customized, typically using one or two additional metallization levels. For example mixed signal (analog/digital) circuits are notoriously difficult to realize with the common semicustom families (CMOS gate arrays for digital and bipolar arrays for analog circuits). Microdul's semicustom arrays have been designed with exactly this market segment in mind. They are manufactured using mature SACMOS technologies. Besides conventional gate array structures they also feature many elements necessary for analog circuit design: different resistors, capacitors, diodes and transistors with special geometries. These arrays allow the development of circuits with digital as well as complex analog functions. As you can see from our examples our semicustom arrays can be optimized for many diffe rent applications.

Wafer service
If you would like to do your own design using our arrays, you can go for our MPW services. You will receive 40 samples packed in a ceramic package typically within 6 weeks of tape-out date.

The Arrays

The MD300 semicustom array is manufactured in a 1µm n-well silicon gate SACMOS process. It contains about 1200 logic gates, 32 EPROM cells, 800 optimized analogue transistors, resistors and capacitors within an area of 1.7mm². All 16 connecting pads have input/output capability and ESD protection components. A particular application can be configured using 3 masks, two metal and one via mask.

The MD300 is specially suited for ultra low power consumption applications. Typical examples for low power circuits can be Quartz watch, RTC, sensors, etc.

Multiproject wafers are started regularly in order to allow cost effective prototyping.

The MD500 semicustom array is based on a 0.9µm n-well silicon gate SACMOS process. There are around 5500 logic gates, 2300 transistors optimised for analogue circuitry, 64 EPROM cells as well as resistors and capacitors avaible on a 4.4mm² chip area. All of the 32 connecting pads have input/output capability and ESD protection components. A particular application can be implemented using two metal masks and two via masks.

The MD500 is specially suited for ultra low power consumption applications. Typical examples for low power circuits can be Quartz watch, RTC, sensors, etc.
