4兆位( 512KB ×8) UV EPROM和OTP EPROM 4 Mbit 512Kb x 8 UV EPROM and OTP EPROM
Summary description
The M27C4001 is a 4 Mbit EPROM offered in the two ranges UV ultra violet erase and OTP one time programmable. It is ideally suited for microprocessor systems requiring large programs and is organised as 524,288 by 8 bits.
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 applications where the content is programmed only one time and erasure is not required, the M27C4001 is offered in PDIP32, PLCC32 and TSOP32 8 x 20 mm packages.
In order to meet environmental requirements, ST offers the M27C4001 in ECOPACK® packages.
