Description

The MR27V12852L-12NTA03A is a 16Mbit electrically Programmable Read-Only Memory (EPROM) with page mode. It can be configured to operate in two modes: 1,048,576 word x 16 bit and 2,097,152 word x 8 bit. This EPROM operates on a single +3.3V power supply and is TTL compatible. It features a page mode that significantly reduces read access time. As an asynchronous device, it does not require external clocks, making it easy to use. The MR27V12852L-12NTA03A is suitable for use as a large-capacity fixed memory in microcomputers and data terminals. It is manufactured using a CMOS double silicon gate technology and is available in 42-pin DIP, 44-pin SOP, 44-pin TSOP, and 48-pin TSOP packages.
