Features
Functional Description The CY27C128 is a high performance 16,384 word by 8 bit CMOS EPROM. When disabled (CE HIGH), the Logic Block Diagram
A 13 A 12 A 11 A 10 A9 ROW ADDRESS 128 x 1024 PROGRAMABLE ARRAY
CY27C128 automatically powers down into a low power stand by mode. The CY27C128 is packaged in the industry standard 600 mil DIP and LCC packages. The CY27C128 is also available in a Cer DIP package equipped with an erasure window to provide for reprogrammability. When exposed to UV light, the EPROM is erased and can be reprogrammed. The memory cells utilize proven EPROM floating gate technology and byte wide in telligent programming algorithms. The CY27C128 offers the advantage of lower power and superior performance and programming yield. The EPROM cell re quires only 12.5V for the super voltage,
128K (16K x 8 Bit) CMOS EPROM
CY27C128
and low current requirements allow for gang programming. The EPROM cells al low each memory location to be tested 100% because each location is written into, erased, and repeatedly exercised prior to encapsulation. Each EPROM is also tested for AC performance to guar antee that after customer programming, the product will meet both DC and AC specification limits. Reading the CY27C128 is accomplished by placing active LOW signals on OE and CE . The contents of the memory location addressed by the address lines (A 0 - A 13 ) will become available on the output lines (O 0 - O 7 ).

Erasure Characteristics
Wavelengths of light less than 4000 A begin to erase the 27C128 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 wave length of 2537 A for a minimum dose (UV intensity multiplied by exposure time) of 25 Wsec/cm mW/cm
2 2
during erasure. Permanent damage may result if the EPROM is exposed to high intensity UV light for an extended period of time. 7258 Wsec/cm

is the recommended maximum dosage.
Programming support is available from Cypress as well as from a number of third party software vendors. For detailed program ming information, including a listing of software packages, please see the EPROM Programming Information located at the end of this section. Programming algorithms can be obtained from any Cypress representative.
. For an ultraviolet lamp with a 12
power rating, the exposure time would be approximately
35 minutes. The CY27C128 needs to be within 1 inch of the lamp
