EPROM OTP 32MBIT 2MX16 100NS 42PDIP

The M27V322 is a 32 Mbit EPROM offered in the UV range (ultra violet erase) and OTP range. It is ideally suited for microprocessor systems requiring large data or program storage. It is organised as 2 MWords of 16 bit. The pin-out is compatible with a 32 Mbit Mask ROM.The FDIP42W (window ceramic frit-seal package) has a transparent lid which allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written rapidly to the device by following the programming procedure.For applications where the content is programmed only one time and erasure is not required, the M27V322 is offered in PDIP42 and SDIP42 packages.In order to meet environmental requirements, ST offers the M27V322 in ECOPACK packages.ECOPACK packages are Lead-free. The category of second Level Interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label.ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com.
