High Speed, see AC Characteristics section for further information. It is recommended that a 0. 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. For the most efficient use of these two control lines, E should be decoded and used as the prima- ry dataaheet selecting function, while G should be made a common connection to all devices in the array and connected to the READ line from the system control bus.

Chip Enable E is the power control and should be used for device selection.

This ensures that all datashwet 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 supply current, Ice, has three seg- ments that are of interest to the system designer: Input or Output Voltage except A9.

A single power sup- ply is required in datwsheet read mode. 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.

The M27C is in the programming mode when Vpp input is at Except for the rating “Operating Temperature Range”, stresses above tinose iisted in tiie Tabie “Absolute Maximum Ratings” may cause permanent damage to the device.

Speed obtained with High Speed AC measurement conditions. Minimum DC voltage on Input or Output is 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.

Address Transition to Output Transition. 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 d evices in the array and connected to the READ line from the system control bus. Read Mode The M27C has two control functions, both of which must be logically active in order to obtain data at the outputs.

When in the standby mode, the outputs are in a high imped- ance state, independent of the G input. The magnitude of the transient current peaks is dependent on the capacitive and inductive loading of the device at the output.

Data is available at the output after a delay. All inputs are TTL levels except for 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. It 27c10001 be noted that sunlight and some type of fluorescent lamps have wavelengths in the A range.

Output Enable G is the output control and should be used to gate data to the output pins, indepen- dent of device selection. Although only ‘O’s will be programmed, both ‘1 ‘s and ‘O’s can be present in the data word.
