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 V_CCand 12.0 Volt V_PPto 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 pin-

out. For applications that do not require in-system-programming (ISP) function for firmwire upgrade, the Pm37LV512

offers a direct cost reduction path for Flash memory, i.e. Pm39LV512, without modifying the schematic and board

layout of system.

The Pm37LV512 is manufactured on PMC’s advanced nonvolatile CMOS technology, P-FLASH™. The device is

offered in 32-pin PLCC, VSOP and PDIP packages with access time of 70 ns.
