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

TYPE INPUT
DESCRIPTION Address Inputs: For memory addresses input. Addresses are internally latched on the falling edge of WE# during a write cycle. Chip Enable: CE# goes low activates the device's internal circuitries for device operation. CE# goes high deselects the device and switches into standby mode to reduce the power consumption. Write Enable: Activate the device for write operation. WE# is active low. Output Enable: Control the device's output buffers during a read cycle. OE# is active low. Data Inputs/Outputs: Input command/data during a write cycle or output data during a read cycle. The I/O pins float to tri-state when OE# are disabled. Device Power Supply Ground No Connection

DEVICE OPERATION
READ OPERATION The access of PM37LV512 is similar as that of EPROM or Flash Memory. To obtain data at the outputs, three control functions must be satisfied: * CE# is the chip enable and should be pulled low ( VIL ). * OE# is the output enable and should be pulled low ( VIL). * WE# is the write enable and should remains high ( VIH ). BYTE PROGRAMMING The PM37LV512 is programmed by using an external EPROM programmer. The programming mode is activated by applying 12.0 Volt on OE# pin and VIL on CE# pin. The byte program operation is completed by asserting WE# to low for 20 s. A chip erase operation is required prior to program due to a data "0" can not be programmed back to a "1" and only erase operation can convert "0"s to "1"s. The entire chip can be programmed byte-by-byte by using the byte program algorithmm. Refer to Chart 1. Byte Programming Flowchart and Byte Program Operations AC Waveforms.
Programmable Microelectronics Corp.
CHIP ERASE The entire memory array can be erased through a chip erase operation on an external EPROM programmer. Pre-program the "1"s cells in the device is not required prior to chip erase operation. The chip erase operation is activated by applying 12.0 Volt to OE# and A9 pins while CE# pin is low. All other address and data pins are "don't care". Chip erase is completed by asserting WE# pin to low for 100 ms. The falling edge of WE# will start the chip erase operation. The device will return back to standby mode after the completion of chip erase. Refer to Chart 2. Chip Erase Flowchart and Chip Erase Operations AC Waveforms. PRODUCT IDENTIFICATION The hardware product identification mode can be used by an EPROM programmer to identify the device and manufacturer for selecting the right programming algorithm for the device. The product identification mode is activated by applying 12.0 Volt on A9 pin. For details, please see Bus Operation Modes in Table 1.
