P4C1041 HIGH SPEED 256K x 16 (4 MEG) STATIC CMOS RAM FEATURES Easy Memory Expansion Using CE and OE Inputs Fully TTL Compatible Inputs and Outputs Advanced CMOS Technology Fast tOE Automatic Power Down when deselected Packages —44-Pin SOJ, TSOP II High Speed (Equal Access and Cycle Times) — 10/12/15/20 ns (Commercial) — 12/15/20 ns (Industrial/Military) Low Power Single 5.0V ± 10% Power Supply 2.0V Data Retention DESCRIPTION The P4C1041 device provides asynchronous operation with matching access and cycle times. Memory locations are specified on address pins A0 to A17. Reading is accomplished by device selection (CE and output enabling (OE) while write enable (WE) remains HIGH. By presenting the address under these conditions, the data in the addressed memory location is presented on the data input/output pins. The input/output pins stay in the HIGH Z state when either CE or OE is HIGH or WE is LOW. The P4C1041 is a 262,144 words by 16 bits high-speed CMOS static RAM. The CMOS memory requires no clocks or refreshing, and has equal access and cycle times. Inputs are fully TTL-compatible. The RAM operates from a single 5.0V ± 10% tolerance power supply. Access times as fast as 10 nanoseconds permit greatly enhanced system operating speeds. CMOS is utilized to reduce power consumption to a low level. The P4C1041 is a member of a family of PACE RAM™ products offering fast access times. Package options for the P4C1041 include 44-pin SOJ and TSOP packages.

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. 2.Extended temperature operation guaranteed with 400 linear feet per minute of air flow. 3.Transient inputs with VIL not more negative than –2.0V and VIH ≤ VCC + 0.5V, are permissible for pulse widths up to 20 ns.

Note: Because of the ultra-high speed of the P4C1041, 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. To avoid signal reflections, proper termination must be used; for example, a 50Ω test environment should be terminated into a 50Ω load with 1.73V (Thevenin Voltage) at the comparator input, and a 116Ω resistor must be used in series with DOUT to match 166Ω (Thevenin Resistance).
