GENERAL DESCRIPTION
The MX27L2000 is a 3V only, 2M-bit, ultraviolet Erasable
Programmable Read Only Memory. It is organized as
256K words by 8 bits per word, operates from a single +
3 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
MX27L2000
2M-BIT [256Kx8] CMOS EPROM
• Standby current: 20uA
• Package type:
- 32 pin ceramic DIP, plastic DIP
- 32 pin SOP
- 8x20mm 32-lead TSOP(I)
- 8x14mm 32-lead TSOP(I)
