1 / 10 page 1 Document # SRAM104 REV B Revised April 2007 DESCRIPTION The P4C148 and P4C149 are 4,096-bit ultra high-speed static RAMs organized as 1K x 4. Both devices have common input/output ports. The P4C148 enters the standby mode when the chip enable (CE) goes HIGH; with CMOS input levels, power consumption is extremely low in this mode. The P4C149 features a fast chip select capability using CS. The CMOS memories require no clocks or refreshing, and have equal access and cycle times. Inputs are fully TTL-compatible. The RAMs operate from a single 5V ± 10% tolerance power supply. P4C148, P4C149 ULTRA HIGH SPEED 1K x 4 STATIC CMOS RAMS FEATURES Full CMOS, 6T Cell High Speed (Equal Access and Cycle Times) – 10/12/15/20/25/35/45/55 ns (Commercial) – 15/20/25/35/45/55 ns (P4C148 Military) Low Power Operation Single 5V ± 10% Power Supply Two Options – P4C148 Low Power Standby Mode – P4C149 Fast Chip Select Control Common Input/Output Ports Three-State Outputs Fully TTL Compatible Inputs and Outputs Standard Pinout (JEDEC Approved) – 18 Pin 300 mil DIP – 18 Pin LCC (295 x 335 mil) [P4C148 only] – 18 Pin LCC (290 x 430 mil) FUNCTIONAL BLOCK DIAGRAM PIN CONFIGURATION Access times as fast as 10 nanoseconds are available, permitting greatly enhanced system operating speeds. CMOS is used to reduce power consumption when active; for the P4C148, consumption is further reduced in the standby mode. The P4C148 and P4C149 are available in 18-pin 300 mil DIP packages, as well as 2 different LCC packages, providing excellent board level densities.
