M<strong>27C512</strong>SUMMARY DESCRIPTIONThe M<strong>27C512</strong> is a 512 Kbit <strong>EPROM</strong> offered in thetwo ranges UV (ultra violet erase) and OTP (onetime programmable). It is ideally suited for applicationswhere fast turn-around and pattern experimentationare important requirements and isorganized as 65536 by 8 bits.The FDIP28W (window ceramic frit-seal package)has transparent lid which allows the user to exposethe chip to ultraviolet light to erase the bit pattern.A new pattern can then be written to thedevice by following the programming procedure.For applications where the content is programmedonly one time and erasure is not required, theM<strong>27C512</strong> is offered in PDIP28, PLCC32 andTSOP28 (8 x 13.4 mm) packages.In addition to the standard versions, the packagesare also available in Lead-free versions, in <strong>com</strong>pliancewith JEDEC Std J-STD-020B, the ST ECO-PACK 7191395 Specification, and the RoHS(Restriction of Hazardous Substances) directive.Figure 2.
