DESCRIPTION The M27W101 is a low voltage 1 Mbit EPROM offered in two range UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems requiring large data or program storage and is organized as 131,072 by 8 bits. The M27W101 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 si ze of t he battery or an increase in the time between battery recharges. The FDIP32W (window ceramic fri t-seal package) has a t ransparent 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 application where the content is programmed only one time and erasure is not required, the M27W101 is offered in 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.
