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
and 12.0 Volt V
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 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.
