DESCRIPTION The M27W512 is a l ow 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 65,536 by 8 bits. The M27W512 operates in t he read mode with a supply voltage as low as 2.7V at 40 to 85°C temperature range. The decrease in operating power allows either a reduction of the size of the battery or an increase in th e t ime between battery recharges. The FDIP28W (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 M27W512 is offered in PDIP28, PLCC32 and TSOP28 (8 x 13.4 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.
