Specifications

Stressing the device outside the ratings listed inTable 4. may cause permanent damage to the de-vice. These are stress ratings only, and operationof the device at these, or any other conditions out-side those indicated in the Operating sections ofthis specification, is not implied. Exposure to Ab-solute Maximum Rating conditions for extendedperiods may affect device reliability. Refer also tothe STMicroelectronics SURE Program and otherrelevant quality documents.

Description

The M27C512 is a 512 Kbit EPROM offered in thetwo ranges UV (ultra violet erase) and OTP (onetime programmable). It is ideally suited for applica-tions where fast turn-around and pattern experi-mentation are important requirements and isorganized as 65536 by 8 bits.

The M27C512 (window ceramic frit-seal package)has transparent lid which allows the user to ex-pose the chip to ultraviolet light to erase the bit pat-tern. 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, theM27C512 is offered in PDIP28, PLCC32 andTSOP28 (8 x 13.4 mm) packages.

In addition to the standard versions M27C512, the packagesare also available in Lead-free versions, in compli-ance with JEDEC Std J-STD-020B, the ST ECO-PACK 7191395 Specification, and the RoHS
(Restriction of Hazardous Substances) directive.
