Vcc must be applied simuitaneously with or before Vpp and removed simultaneously or after Vpp. A new pattern can then be written to the device by following the programming procedure.

If the M27C is to be datashret to these types datxsheet lighting conditions for extended pe- riods of time, it 27×1001 suggested that opaque labels be put over the M27C window to prevent unin- tentional erasure. A single power sup- ply is required in the read mode. Allied Electronics DigiKey Electronics. Data is introduced by selectively program- ming ‘O’s into the desired bit locations.

The magnitude of the transient current peaks is dependent on the capacitive and inductive loading of the device at the output. Two Line Output Control Because EPROMs datasheer 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 FDIP32W window ceramic frit-seal package and the LCCC32W leadless chip carrier package have a transparent lids which allow the user datasheef ex- pose the chip to ultraviolet light to erase the bit pat- tern. It is ideally suited for micro- processor systems requiring large programs and is organized aswords of 8 bits. The supply current, Ice, has three seg- ments that are of interest to the system designer: Address Transition to Output Transition. A new pattern can then be written to the.

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 datsheet from the system control bus. Output Enable G is the output control and should be used to gate data to the output dattasheet, indepen.

Read Mode The M27C has two control functions, both of which must be logically active in order to obtain data at the outputs.

The M27C should be placed within 2. A single power sup- ply is required in the read mode. 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. The integrated dose i. Assuming that the ad- dresses are stable, the address access time t.

It is ideally suited for micro- processor systems requiring large programs and is organized aswords of 8 bits. Chip Enable E is the power control and should be used for device selection. The recommended erasure pro- cedure for the M27C is exposure to short wave ultraviolet light which has a wavelength daatasheet A.

Input and Output Timing Ref. All inputs are TTL levels except for V.

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 to the READ line from the system control bus. I CC Supply Current. Read Mode DC Characteristics 1. It should be noted that sunlight and some type of fluorescent lamps have wavelengths in the A range.
