The MX27C1000 is a 5V only, 1M-bit, One Time Programmable Read Only Memory. It is organized as 128K 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 program- ming signals are TTL levels, requiring a single pulse. For programming outside from the system, existing EPROM programmers may be used. The MX27C1000 supports an intelligent fast programming algorithm which can result in programming time of less than thirty seconds. This EPROM is packaged in industry standard 32 pin dual-in-line packages, 32 lead PLCC , 32 lead SOP , and 32 lead TSOP packages.
The MX27C1000 is a 5 V‑only, 1 M‑bit One‑Time‑Programmable Read‑Only Memory organized as 128K × 8. It operates from a single +5 V supply, offers static standby mode, and provides fast access times ranging from 45 ns to 150 ns. All programming signals are TTL‑level, and the device is fully TTL compatible.
Programming uses a +12.5 V (VPP) supply with a single low‑level pulse on the PGM pin. The EPROM supports fast programming, program‑verify, and program‑inhibit modes, and includes CMOS and TTL standby modes to reduce power consumption. It is offered in 32‑pin DIP, SOP, PLCC, and TSOP packages.
