When disabled (CEBAR HIGH), the QP7C271 automatically powers down into a low-power stand-by mode. The QP7C271 is packaged in the 300-mil slim package. The QP7C271 is available in a hermetic package equipped with an erasure window to provide for re-programmability. When exposed to UV light, the PROM is erased and can be reprogrammed. The memory cells utilize proven EPROM floating gate technology and byte-wide intelligent programming algorithms. The QP7C271 offers the advantage of lower power, superior performance, and programming yield. The EPROM cell requires only 12.5V for the super voltage, and low current requirements allow for gang programming. The EPROM cells allow each memory location to be tested 100% because each location is written into, erased, and repeatedly exercised prior to encapsulation. Each PROM is also tested for AC performance to guarantee that after customer programming, the product will meet DC and AC specification limits. Reading the QP7C271 is accomplished by placing active LOW signals on CS1 BAR and CEBAR, and an active HIGH on CS2. The contents of the memory location addressed by the address lines (A0 - A14) will become available on the output lines (O0 - O7). The device is available in windowed hermetic package (Erasable when exposed to UV light) and is also available in non-windowed OTP (One-Time-Programmable) hermetic or plastic packages.

Erasure Characteristics: Wavelengths of light less than 4000 Angstroms begin to erase these PROMs. For this reason, an opaque label should be placed over the window if the PROM is exposed to sunlight or fluorescent lighting for extended periods of time. The recommended dose of ultraviolet light for erasure is a wavelength of 2537 Angstroms for a minimum dose (UV intensity x exposure time of 25 Wsec/cm2. For an ultraviolet lamp with a 12 mW/cm2 power rating, the exposure time would be approximately 35 minutes. These PROMs need to be within 1 inch of the lamp during erasure. Permanent damage may result if the PROM is exposed to high-intensity UV light for an extended period of time. 7258 Wsec/cm2 is the recommended maximum dosage. Programming Information: The QP7C271 programs using the same programming algorithm as Cypress 7C271. A variety of programming equipment currently supports the Cypress Algorithm. QP Semiconductor has verified that the devices program on Data I/O Unisite and on a programmer supplied by EETools.
