DESCRIPTION The M 27C801 is an 8 Mbit EPROM of fered in the two ranges UV (ultra violet erase) and O TP (one time programmable). It is ideally suited for applications where fast turn-around and pattern experimentation are important requirements and is organized as 1,048,576 by 8 bits. The FDIP32W (window ceramic fri t-seal package) has 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 to the device by following the programming procedure. For applications where the content is programmed only one time and erasure is not required, the M27C801 is of fered i n PDIP32, PLCC32 and TSOP32 (8 x 20 mm) packages.

Note: 1. Except for the rating " Operating T emperature R ange", stresses above those liste d in the Table "A bsolute Maximum R atings" may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above t hose indicated in t he Operating sections of t his s pecification is not impl ied. Exposure t o A bsolute M aximum R ating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents. 2. Minimum DC voltage on Input or O utput is 0.5V with possible undershoot to 2.0V for a period les s than 20ns. M aximum DC voltage on O utput is VCC +0.5V with possible overshoot to VCC + 2V for a period less than 20ns. 3. Depends on range.
