File Size : 116 KB Manufacturer:72 Description:The M27W512 is a low voltage 512 Kbit EPROM offered in the two range UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems and is organized as 65536 by 8 bits. The M27W512 operates in the read mode with a supply voltage as low as 2.7V at C40 to 85C tem- perature range. The decrease in operating power allows either a reduction of the size of the battery or an increase in the time between battery re- charges. The FDIP28W (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 the device by following the programming procedure. For applications where the content is programmed only one time and erasure is not required, the M27W512 is offered in PDIP28, PLCC32 and TSOP28 (8 x 13.4 mm) packages. In addition to the standard versions, the packages are 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.
