CY27H010
128K x 8 High-Speed CMOS EPROM
Features
* CMOS for optimum speed/power * High speed -- tAA = 25 ns max. (commercial) -- tAA = 35 ns max. (military) * Low power -- 275 mW max. * * * * * -- Less than 85 mW when deselected Byte-wide memory organization 100% reprogrammable in thewindowed package EPROM technology Capable of withstanding >2001V static discharge Available in -- 32-pin PLCC -- 32-pin TSOP-I -- 32-pin, 600-mil plastic or hermetic DIP -- 32-pin hermetic LCC try-standard 32-pin, 600-mil DIP, LCC, PLCC, and TSOP-I packages. These devices offer high-density storage combined with 40-MHz performance. The CY27H010 is available in windowed and opaque packages. Windowed packages allow the device to be erased with UV light for 100% reprogrammability. The CY27H010 is equipped with a power-down chip enable (CE) input and output enable (OE). When CE is deasserted, the device powers down to a low-power stand-by mode. The OE pin three-states the outputs without putting the device into stand-by mode. While CE offers lower power, OE provides a more rapid transition to and from three-stated outputs. The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming algorithms. The EPROM cell requires only 12.75 V for the supervoltage and low programming current allows for gang programming. The device allows for each memory location to be tested 100%, because each location is written to, erased, and repeatedly exercised prior to encapsulation. Each device is also tested for AC performance to guarantee that the product will meet DC and AC specification limits after customer programming. The CY27H010 is read by asserting both the CE and the OE inputs. The contents of the memory location selected by the address on inputs A16-A0 will appear at the outputs O7-O0.

Erasure Characteristics
Wavelengths of light less than 4000 Angstroms begin to erase the CY27H010 in the windowed package. For this reason, an opaque label should be placed over the window if the EPROM 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 multiplied by 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. The CY27H010 needs to be within 1 inch of the lamp during erasure. Perma-
nent damage may result if the EPROM is exposed to high-intensity UV light for an extended period of time. 7258 Wsec/cm2 is the recommended maximum dosage.
Programming Modes
Programming support is available from Cypress as well as from a number of third-party software vendors. For detailed programming information, including a listing of software packages, please see the PROM Programming Information located at the end of this section. Programming algorithms can be obtained from any Cypress representative.
