Product Summary
The 27C256-15 is a 5V only, 256K-bit, One-Time Programmable Read Only Memory. It is organized as 32K by 8 bits, operates from a single + 5volt supply, has a static standby mode, and features fast single address location programming. All programming signals of 27C256-15 are TTL levels, requiring a single pulse. For programming from outside the system, existing EPROM programmers may be used. The 27C256-15 supports intelligent fast programming algorithm which can result in programming time of less than ten seconds.
