TECHNOLOGY
The MX26C512A is a 12.75V/5V, 512K-bit, MTP
EPROM^TM (Multiple Time Programmable Read Only
Memory). It is organized as 64K words by 8 bits per word,
operates from a + 5 volt supply, has a static standby
mode, and features fast single address location program-
ming. It is designed to be reprogrammed and erased by
an EPROM programmer or on-board. All programming/
erasing signals are TTL levels, requiring a single pulse.
The MX26C512A supports an intelligent quick pulse
programming algorithm which can result in a program-
ming time of less than 30 seconds.
This MTP EPROM^TM is packaged in industry standard 28
pin dual-in-line packages, 32 pin PLCC packages or 28
pin TSOP packages and 28 pin SOP packages.
