PY263/PY264 8K x 8 REPROGRAMMABLE PROM FEATURES EPROM Technology for reprogramming Windowed devices for reprogramming High Speed Fully TTL Compatible Inputs and Outputs – 25/35/45/55 ns (Commercial) – 25/35/45/55 ns (Military) Low Power Operation: – 660 mW Commercial – 770 mW Military Standard Pinout (JEDEC Approved) – 24-Pin 300 mil Windowed CERDIP (PY263) – 24-Pin 300 mil Non-Windowed Plastic DIP (PY263) – 24-Pin 600 mil Windowed CERDIP (PY264) – 24-Pin 600 mil Non-Windowed Plastic DIP (PY264) Single 5V±10% Power Supply DESCRIPTION The PY263 and PY264 are 8Kx8 CMOS PROMs. The devices are available in windowed packages which when exposed to UV light, the memory content in the PROM is erased and can be reprogrammed. EPROM technology is used in the memory cells for programming. The EPROM requires a 12.5V for programming. Devices are tested to insure that performance of the device meets the DC and AC specification limits after customer programming. Functional Block Diagram To perform a read operation from the device, CS is LOW. The memory contents in the address established by the Address pins (A0 to A12) will become available on the outputs (O0 to O7). The PY263 is available in 24-pin 300 mil Ceramic DIPs (Windowed) and Plastic DIPs (Non-Windowed). The PY264 is available in 24-pin 600 mil Ceramic DIPs (Windowed) and Plastic DIPs (Non-Windowed).

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to Maximum rating conditions for extended periods may affect reliability. Document # EPROM102 REV A 2.Extended temperature operation guaranteed with 400 linear feet per minute of air flow. 3.Transient inputs with VIL and IIL not more negative than –3.0V and –100mA, respectively, are permissible for pulse widths up to 20 ns. 4.This parameter is sampled and not 100% tested. Page 3 PY263/PY264 - 8K x 8 REPROGRAMMABLE PROM DEVICE ERASURE READ MODE If the device is subjected to wavelengths of light below 4000 Angstroms, device erasure will commence. It is therefore recommended to use an opaque label over the window in the event the device will be exposed to lighting for a long time. The UV dose for erasure requires a wavelength of 2,537 Angstroms for a minimum dose of 25 Wsec/cm2. If using a UV lamp of 12 mW/cm2, the exposure time is estimated to be 35 minutes. Devices should be positioned within 1 inch of the lamp during the erasure process. Permanent damage can occur to the devices if exposed to UV light for an extended period of time. Reading the addressed content is the normal operating mode for a programmed device. Signals are at normal TTL levels. Addressing is applied to the 13 address pins and CS is LOW. Under these conditions, the addressed location contents are presented to the output pins.

Thevenin Equivalent Note: Because of the ultra-high speed of the PY263/PY264, care must be taken when testing this device; an inadequate setup can cause a normal functioning part to be rejected as faulty. Long high-inductance leads that cause supply bounce must be avoided by bringing the VCC and ground planes directly up to the contactor fingers. A 0.01 µF high frequency capacitor is also required between VCC and ground. * including scope and test fixture.
