M27W101 1兆位( 128KBx8 )低压紫外可擦写可编程只读存储器和OTP存储器
ST将长期致力于EPROM的开发。
ST将致力于和客户建立长期的业务伙伴关系,长期开发EPROM产品。我们的持续投资证明这一点。无论是现在和将来,我们将在产能、工艺以及产品组合等方面投入大量资金,以巩固ST在EPROM领域的世界领袖地位。
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 the 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 the time between battery recharges.The FDIP32W (window ceramic frit-seal package) has a 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 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.
In order to meet environmental requirements, ST offers the M27W101 in ECOPACK?packages. ECOPACK packages are Lead-free. The category of second Level Interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label
