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. Read Mode AC Characteristics 1. The magnitude of the transient current peaks is dependent on the capacitive and inductive loading of the device at the output. I CC Supply Current.

The bulk capacitor should be located near the power supply connection point. A new pattern can then be written to the device by following 27f1001 programming procedure.

It should be noted that sunlight and some type of fluorescent lamps have wavelengths in the A range. When in the standby mode, the outputs aj: This mode is intended for use by programming equipment to automatically match the device to be programmed with its corresponding programming algorithm.

Output Enable Low to Output Valid. Two Line Output Control Because EPROMs are datzsheet used in larger memory arrays, this product features a 2 line con- trol function which accommodates the use of mul- tiple memory connection. The supply current, Ice, has three seg- ments that are of interest to the system designer: It is recommended that a 0.

Exposure to Absolute Maximum Rating condi- tions for extended periods 27f1001 affect device reliability. Input and Output Timing Ref.

Two Line Output Control. For the most efficient use of these two control. Search the history of over billion web pages on the Internet. The M27C is in the programming mode when Vpp input is at Read Mode DC Characteristics 1. Except for the rating “Operating Temperature Range”, stresses above tinose iisted in datasheeh Tabie “Absolute Maximum Ratings” may cause permanent damage to the device.

Data is available at the output after a delay. Exposure to Absolute Maximum Rating condi- tions for extended periods may affect device reliability.

Ordering Information Scheme Example: Output Enable G is the output control and should be used to gate data to the output pins, indepen- dent of device selection.

Address Valid to Output Valid. Address Transition to Output Transition. 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. STMicroeiectronics products are not authorized for use as critical components in life support devices or systems without express written approval of STMicroeiectronics. A new pattern can then be written to the device by following the programming procedure.

However, STMicroeiectronics assumes no responsibility for the consequences of use of such information nor for any infringement of patents or other rights of third parties which may result from its use.

The M27C should be placed within 2. When in the standby mode, the outputs are in a high imped- ance state, independent of the G input.

AC Testing Load Circuit. For applications where the content is programmed. E has been low and the addresses have been sta- ble for at least t. The two line control function allows: This ensures that all deselect- ed memory devices are in their low power standby mode and that the output pins are only active when data is required from a particular memory device. The updated every day, always provide the best quality and speed. High Speed, see AC Characteristics section for further information.

The data to be programmed is applied to 8 bits in parallel to the data output pins. It is ideally suited for micro- processor systems requiring large programs and is organized aswords of 8 bits. Although only ‘O’s will be programmed, both ‘1 ‘s and ‘O’s can be present in the data word.

Read Mode DC Characteristics. Two identifier bytes may then be sequenced from the device out- puts by toggling address line AO from ViLto Vih. Maximum DC voltage on Output is V. 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. Assuming that the ad- dresses are stable, the address access time t. A new pattern can then be written to the.

In addi- tion, a 4.

This ensures that all deselect- ed memory devices are in their low power datashedt mode and that the output pins are only active when data is required from a particular memory device.
