Ordering Information Scheme Example: When in the standby mode, the outputs are in a high imped- ance state, independent of the G input. I PP Program Current. The supply current, Ice, has three seg- ments that are of interest to the system designer: STMicroeiectronics products are not authorized for use as critical components in life support devices or systems without express written approval of STMicroeiectronics.
Output Enable Low to Output Valid. Data is available at the output after a delay. The bulk capacitor should be located near the power supply connection point.

Output Enable G is the output control and should be used to gate data to the output pins, indepen- dent of device selection. Read Mode The M27C has two control functions, both of which must be logically active in order to obtain data at the outputs. Input and Output Timing Ref. The updated every day, always provide the best quality and speed.
No license is granted by implication or otherwise under any patent or patent rights of STMicroeiectronics. Exposure to Absolute Maximum Rating condi- tions for extended periods may affect device reliability. Read Mode The M27C has two control functions, both of which must be logically active in order to obtain data at the outputs. A single power sup- ply is required in the read mode.
Read Mode DC Characteristics 1. Exposure to Absolute Maximum Rating condi- tions for extended 27c11001 may affect device reliability. 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.
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. To activate the ES mode, the programming equipment must force A new pattern can then be written to the device by following the programming procedure.
The two line control. 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. When in the standby mode, the outputs aj: Although only ‘O’s will be programmed, both ‘1 27f1001 and ‘O’s can be present in the data word.
In addi- tion, a 4.
Allied Electronics DigiKey Electronics. A new pattern can then be written to the device by following the programming procedure. Datxsheet single power sup- ply is required in the read mode.
High Speed, see AC Characteristics section for further information. 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.
This mode is intended for use by programming equipment to automatically match the device to be programmed with its corresponding programming algorithm. Address Transition to Output Transition. The FDIP32W window ceramic frit-seal package and the LCCC32W leadless chip carrier package have a transparent lids which datashert the user to ex- pose 27c1010 chip to ultraviolet light to erase the bit pat- tern.
This ensures that all deselect. Vcc must be applied simultaneously with or before Vpp and removed simultaneously or after Vpp. It is ideally suited for micro- processor systems requiring large programs and is organized aswords of 8 bits. The associated transient voltage peaks can be suppressed by complying with the two line output control and by properly selected decoupling capacitors. TSOP32 8 x 20 mm packages. Read Mode DC Characteristics. The M27C should be placed within 2. I CC Supply Current.
The purpose of the bulk capacitor is to overcome the voltage drop caused by the inductive effects of PCB traces.

Two Line Output Control Because EPROMs datashewt usually used in larger memory arrays, this product features a 2 line con- trol function which accommodates the use of mul- tiple memory connection. Two identifier bytes may then be sequenced from the device out- puts by toggling address line AO from ViLto Vih.
