Part Details:

M27V102 1 Mbit (64Kb x16) Low Voltage UV EPROM and OTP EPROM NOT FOR NEW DESIGN s M27V102 is replaced by the M27W102 s LOW VOLTAGE READ OPERATION: 3V to 3.6V s ACCESS TIME: 90ns s LOW POWER CONSUMPTION: 40 40 ­ Active Current 15mA at 5MHz ­ Standby Current 20µA 1 1 FDIP40W (F) PDIP40 (B) s PROGRAMMING VOLTAGE: 12.75V ± 0.25V s PROGRAMMING TIME: 100µs/word s ELECTRONIC SIGNATURE ­ Manufacturer Code: 20h ­ Device Code: 8Ch DESCRIPTION PLCC44 (K) TSOP40 (N) 8 x 20 mm The M27V102 is a low voltage 1 Mbit EPROM of-fered in the two ranges UV (ultra violet erase) andOTP (one time programmable). It is ideally suitedfor microprocessor systems requiring large data orprogram storage and is organized as 65,536 Figure 1. Logic Diagram words by 16 bits.The M27V102 operates in the read mode with asupply voltage as low as 3V. The decrease in op-erating power allows either a reduction of the size V V of the battery or an increase in the time between CC PP battery recharges. The FDIP40W (window ceramic frit-seal package)has a transparent lid which allows the user to ex- 16 16 pose the chip to ultraviolet light to erase the bit pat- A0-A15 Q0-Q15 tern. A new pattern can then be written to thedevice by following the programming procedure.For application where the content is programmed P M27V102 only one time and erasure is not required, theM27V102 is offered in PDIP40, PLCC32 and E TSOP40 (10 x 14 mm) packages.
