GENERAL DESCRIPTION
The Pm37LV512 is a 512 Kbit, Multiple-Cycle-Programmable Read-Only-Memory (MCP ROM) organized as 65,563 bytes of 8 bits each. The program and erase operation of device can be done on EPROM programmers by applying 3.0 Volt VCC and 12.0 Volt VPP to A9 and/or OE# pin. This eliminates the need of a UV-Source for erase operation such as EPROM device. The read operation of device can be in 2.7 Volt to 3.6 Volt or 4.5 Volt - 5.5 Volt range compatible to either 3.0 Volt or 5.0 Volt systems. The dual read operation ranges can greatly increase application flexibility for users. The device has a standard microprocessor interface as well as JEDEC single-power-supply Flash compatible pinout. For applications that do not req……
