Vcc must be applied simultaneously with or before Vpp and removed simultaneously or after Vpp.

Except for the rating “Operating Temperature Range”, stresses above tinose iisted in tiie Tabie “Absolute Maximum Ratings” may cause permanent damage to the device. High Speed, see AC Characteristics section for further information. It offers a large amount of data sheet, You can free PDF files download. I PP Program Current. A high level E input inhibits the other M27Cs from being programmed. Output Enable Low datazheet Output Valid. The recommended erasure pro- cedure for the M27C is exposure to short wave ultraviolet light which has a wavelength of A.

The two line control. The data to be programmed is applied to 8 bits in parallel to the data output pins. Exposure to Absolute Maximum Rating condi- tions for extended periods may affect device reliability.

This publication supersedes and replaces all information previously supplied. For applications where the content is programmed. The updated every day, always provide the best quality and speed. Specifications mentioned in this datqsheet are subject to change without notice. The associated transient voltage peaks can be suppressed by complying with the two dwtasheet output control and by properly selected decoupling capacitors.

Chip Enable E datasgeet the power control and should be used for device selection. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied.

Output Enable G is the output control and should be used to gate data to the output pins, indepen- dent of device selection. It is recommended that a 0. For the most efficient use of these two control lines, E should be decoded and used as the prima- ry device selecting function, while G should be made a common connection to all devices in the array and connected dagasheet the READ line from the system control bus.

Vcc is specified to be 6. AC Testing Load Circuit 1. E has been low and the addresses have been sta- ble for at least t. Read Mode DC Characteristics. Program Inhiibit Programming of multiple M27CS in parallel with different data is also easily accomplished. Input and Output Dtasheet Ref. Arrow Electronics Mouser Electronics.

Dwtasheet should be noted that sunlight and some type of 27c11001 lamps have wavelengths in the A range.

For a list of available options Speed, Package, etc. Program Verify A verify read should be performed on the pro- grammed bits to determine that they were correct; ly programmed.

The FDIP32W window ceramic frit-seal package and the LCCC32W leadless chip carrier package have a transparent lids which allow the user to ex- pose the chip to ultraviolet light to erase the bit pat- tern. If the M27C is to be exposed to these types of lighting conditions for extended pe- riods of time, it is suggested that opaque labels be put over the M27C window to prevent unin- tentional erasure. The supply current, Ice, has three seg- ments that are of interest to the system designer: A new pattern can then be written to the device by following the programming procedure.

When in the standby mode, the outputs aj: Chip Enable Low to Output Valid. Read Mode The M27C has two control functions, both of which datasheeh be logically active in order to obtain data at the outputs.

Speed obtained with High Speed AC measurement conditions. Speed obtained with High Speed AC measurement conditions.

Two Line Output Control Because EPROMs are usually used in larger memory arrays, this product features a 2 line con- trol function which accommodates the use of mul- tiple memory connection.
