GENERAL DESCRIPTION
The MX27C2000A is a 5V only, 2M-bit, One Time Programmable Read Only Memory.
It is organized as 256K words by 8 bits per word, operates from a single + 5 volt supply, has a static standby mode, and features fast single address location programming.
All programming signals are TTL levels, requiring a single pulse.
For programming outside from the system, existing EPROM programmers may be used.
The MX27C2000A supports a intelligent fast programming algorithm which can result in programming time of less than one minute.
This One Time Programmable Read Only is packaged in industry standard 32 pin dual-in-line packages, 32 lead PLCC, 32 lead SOP, 32 lead TSOP packages.
