CY7C274-45WMB

CY7C271 CY7C274 32K x 8 Power Switched and Reprogrammable PROM Features • CMOS for optimum speed/power • Windowed for reprogrammability • High speed — 30 ns (Commercial) — 35 ns (Military) • Low power — 660 mW (commercial) — 715 mW (military) • Super low standby power • • • • — Less than 165 mW when deselected EPROM technology 100% programmable Slim 300-mil package (7C271) Direct replacement for bipolar PROMs Capable of withstanding >2001V static discharge low-power stand-by mode. The CY7C271 is packaged in the 300-mil slim package. The CY7C274 is packaged in the industry standard 600-mil package. Both the CY7C271 and CY7C274 are available in a cerDIP package equipped with an erasure window to provide for reprogrammability. 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 CY7C271 and CY7C274 offer 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 7C271 is accomplished by placing active LOW signals on CS1 and CE, and an active HIGH on CS2. Reading the 7C274 is accomplished by placing active LOW signals on OE and CE. The contents of the memory location addressed by the address lines (A0−A14) will become available on the output lines (O0−O7). Functional Description The CY7C271 and CY7C274 are high-performance 32,768-word by 8-bit CMOS PROMs. When disabled (CE HIGH), the 7C271/7C274 automatically powers down into a Logic Block Diagram A14 A13 A12 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 Y ADDRESS X ADDRESS 256 x 1024 PROGRAMABLE ARRAY 8 x 1 OF 128 MULTIPLEXER Pin Configurations DIP/Flatpack O7 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 O0 O1 O2 O3 GND 1 2 3 4 28 27 26 VCC A10 A11 A12 A13 A14 CS1 CS2 CE O7 O6 O5 O4 O3 VPP A12 A7 A6 A5 A4 A3 A2 A1 A0 O0 O1 O2 GND DIP/Flatpack 1 2 3 4 28 27 26 VCC A14 A13 A8 A9 A11 OE A10 CE O7 O6 O5 O4 O3 O6 O5 25 5 24 6 7C271 23 22 7 21 8 9 10 11 12 13 14 20 19 18 17 16 15 25 5 24 6 7C274 23 22 7 21 8 9 10 11 12 13 14 20 19 18 17 16 15 O4 LCC/PLCC (Opaque Only) A7 A8 A9 NC V CC A10 A11 O2 4 3 2 1 32 31 30 29 5 28 7C271 6 27 7 26 8 25 9 24 10 23 11 22 12 21 13 14151617 181920 O1 O2 GND NC O3 O4 O5 LCC/PLCC (Opaque Only) 4 3 2 1 32 31 30 29 5 28 7C274 6 27 7 26 8 25 9 24 10 23 11 22 12 21 13 14151617 181920 O1 O2 GND NC O3 O4 O5 A7 A12 VPP NC V CC A14 A13 O1 POWER-DOWN O0 CE (7C271) CS1 (7C271) CS2 (7C274) OE A6 A5 A4 A3 A2 A1 A0 NC O0 A12 A13 A14 NC CS1 CS2 CE O7 O6 A6 A5 A4 A3 A2 A1 A0 NC O0 A8 A9 A11 NC OE A10 CE O7 O6 Cypress Semiconductor Corporation Document #: 38-04008 Rev. *C • 198 Champion Court • San Jose, CA 95134-1709 • 408-943-2600 Revised August 17, 2006 [+] [+] Feedback CY7C271 CY7C274 Selection Guide 7C274-30 Maximum Access Time Maximum Operating Current Standby Current Com’l Military Com’l Military 30 30 120 7C271-35 7C274-35 35 120 130 30 40 7C271-45 7C274-45 45 120 130 30 40 7C271-55 55 120 130 30 40 Unit ns mA mA mA mA Maximum Ratings[1] (Above which the useful life may be impaired.

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 × 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 CY7C271 or CY7C274 needs to be within 1 inch of the lamp during erasure. Permanent damage may result if the Note 7. CS2 and CS1 are used on the 7C271 only. OE is used on the 7C274 only. PROM 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.
