Mouser offers inventory, pricing, & datasheets for Microchip 27c EPROM. 27C 4 Megabit ( K X 8-bit) CMOS EPROM. s Fast access time Available in speed options as fast ns s Low power consumption <10 µA typical CMOS.

Integrated Product Identification Code. Commercial and Industrial Temperature Ranges. The AT27C requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 70 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems.

27C (ATMEL) – 4-megabit k X 8 Otp Eprom | eet

27040 Atmel’s scaled CMOS technology provides low active power consumption, and fast program- ming. Power consumption is typically 8 mA in active mode and less than The device features two-line control CE, OE to eliminate bus contention in high-speed systems.

Atmel’s AT27C has additional features to ensure high quality and efficient production use. The Rapid Programming Algorithm reduces the time required to program the part and guaran- tees reliable programming.

Programming time is typically only Product Identification Code electronically identifies the device and manufacturer. This feature is used datazheet industry standard programming equipment to select the proper programming algo- rithms and voltages. Switching between active and standby conditions via the Chip Enable pin may produce tran- sient voltage excursions.

Unless accommodated by the system design, these transients may exceed datasheet limits, resulting in device non-conformance. At a minimum, a 0. This capacitor should be connected between the V. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, 277c040 4. F bulk electrolytic capacitor should be utilized, again.

27C (Philips) – 4 Meg Coms Eprom(k X 8)

This capacitor should be positioned as. Refer to Programming Characteristics 3. Two identifier bytes may be selected.

All Ai inputs are held low V. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent dam- age to the device.

This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Voltage on Any Pin with Respect to Ground Voltage on A9 with Respect to Ground The supply current would then be the datzsheet of I.
