Products: ASICs [ Gate Arrays, Embedded Arrays, and Standard Cells ]

The Gate Array is a member of the ASIC family that offers Quick Turn Around Time during the development cycle at the lowest development cost. This is achieved by Epson stocking pre-fabricating Base/Bulk wafers that have transistors arranged in the form of an array. Our customers design the "wiring", that connects the transistors, that bring specific functionality to the design of the ASIC.
Bulk wafers are prefabricated with a different numbers of transistors giving customers a wide range of choices to implement their circuits, thereby giving customers a choice of adding or subtracting functionality from the design offering flexibility.

Details of Gate Arrays

The Embedded Array combines the fast turn around time of gate arrays with the ability to implement system level functionality available in Standard Cell. The fast turn around is accomplished by starting some of the wafer fabrication processes in parallel with the Embedded array design process. In selecting an Embedded Array approach, the designer trades off the ability to change the Bulk in the last minute, possible with a gate array, with the need to implement system level functionality, with gate array like turn around.
By offering Gate Array, Standard Cells, and Embedded Arrays;Epson offers a choice to meet the individual needs of our customers.

Standard cells are semi-custom ICs that enable optimally designed internal logic cells, memories such as ROM and RAM, CPU, and analog circuits to be implemented all on the same chip. As such, standard cells enable more design flexibility than do gate arrays, offer more advanced functionality and higher integration,and can be developed as system LSI optimized for the customer's needs. Such optimization allows achieving ever more advanced functionality and low power consumption.

Lineup of macro cells to cover a wide range of user's needs

Macro Cells are indispensable elements for system LSI. Epson offers a wide range of products using for PC peripheral equipment and mobile information devices,including 32-bit RISC and high-speed serial data interface controllers. A unique system LSI is realized by incorporating them into embedded arrays and standard cells, featuring Epson's Energy Saving technology.

Development of low-voltage system power supplies continues as part of the trend toward reducing power consumption. However, in cases where all of the system components cannot run on a single low-voltage power supply, multiple power supplies are used for the same system. Consequently, many of today's portable electronic devices include a dual (5V / 3.3V) power supplies, each with its own signals.

Given the trend toward ever more advanced and compact electronic devices, packaging technologies for high-destiny implementation of highly integrated, high-speed ASIC chips have become increasingly important. Consequently Epson provides a broad lineup of packages to meet customers'diverse packaging needs for chips with widely ranging lead counts and geometries.
