1,743 views

The 511000 is the new generation dynamic RAN organized 1,048,576 words by 1 bit. The TC511000 utilizes TOSHIBA’s CHAOS Silicon gate process technology as well as advanced circuit techniques to provide wide operating margins, both internally and to the system user. Multiplexed address inputs permit the 511000 to be packaged in a standard 18 pin plastic DIP, 26/20 pin plastic SOJ and 20/19 pin plastic ZIP.

The package size provides high system bit densities and is compatible with widely available automated testing and insertion equipment. System-oriented features include a single power supply of 5V±10% tolerance” direct interfacing capability with high-performance logic families such as Schottky TTL. IJTest Mode” function is implemented from Television.
