| P4C1049/P4C1049L HIGH SPEED 512K x 8 STATIC CMOS RAM FEATURES High Speed (Equal Access and Cycle Times) -- 15/20/25 ns (Commercial) -- 20/25/35 ns (Industrial) -- 20/25/35/45/55/70 ns (Military) Low Power Single 5V10% Power Supply Easy Memory Expansion Using CE and OE Inputs Common Data I/O Three-State Outputs Fully TTL Compatible Inputs and Outputs Advanced CMOS Technology Automatic Power Down Packages --36-Pin SOJ (400 mil) --36-Pin FLATPACK --36-Pin LCC (452 mil x 920 mil) DESCRIPTION The P4C1049 is a 4 Megabit high-speed CMOS static RAM organized as 512Kx8. 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 5V10% tolerance power supply. Access times as fast as 15 nanoseconds permit greatly enhanced system operating speeds. CMOS is utilized to reduce power consumption to a low level. The P4C1049 is a member of a family of PACE RAMTM products offering fast access times. The P4C1049 device provides asynchronous operation with matching access and cycle times. Memory locations are specified on address pins A0 to A18. 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.

Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. 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 and IIL not more negative than -2.0V and -100mA, respectively, are permissible for pulse widths up to 20 ns. 4. This parameter is sampled and not 100% tested. 5. WE is HIGH for READ cycle. 6. CE is LOW and OE is LOW for READ cycle. 7. ADDRESS must be valid prior to, or coincident with CE transition LOW. 8. Transition is measured 200 mV from steady state voltage prior to change, with loading as specified in Figure 1. This parameter is sampled and not 100% tested. 9. Read Cycle Time is measured from the last valid address to the first transitioning address.

CE and WE must be LOW for WRITE cycle. 11. OE is LOW for this WRITE cycle to show tWZ and tOW. 12. If CE goes HIGH simultaneously with WE HIGH, the output remains in a high impedance state 13.

Output Load * including scope and test fixture. Note: Because of the ultra-high speed of the P4C1049, 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 F high frequency capacitor is also required between VCC and ground. To avoid Figure 2. Thevenin Equivalent signal reflections, proper termination must be used; for example, a 50 test environment should be terminated into a 50 load with 1.73V (Thevenin Voltage) at the comparator input, and a 116 resistor must be used in series with DOUT to match 166 (Thevenin Resistance).
