DATA SHEET
MOS INTEGRATED CIRCUIT
µPD4443362
4M-BIT CMOS SYNCHRONOUS FAST STATIC RAM 128K-WORD BY 36-BIT HSTL INTERFACE / REGISTER-REGISTER / LATE WRITE
Description
The µPD4443362 is a 131,072 words by 36 bits synchronous static RAM fabricated with advanced CMOS technology using Full-CMOS six-transistor memory cell. The µPD4443362 is suitable for applications which require synchronous operation, high-speed, low voltage, highdensity memory and wide bit configuration, such as cache and buffer memory. The µPD4443362 is packaged in 100-pin plastic LQFP with a 1.4 mm package thickness for high density and low capacitive loading.
Features
· Fully synchronous operation · HSTL Input / Output levels
5
· Fast clock access time : 3.8 ns (133 MHz) · Asynchronous output enable control : /G · Byte write control : /SBa (DQa1-9), /SBb (DQb1-9), /SBc (DQc1-9), /SBd (DQd1-9) · Common I/O using three-state outputs · Internally self-timed write cycle · Late write with 1 dead cycle between Read-Write · 3.3 V (Chip) / 1.5 V (I/O) supply · 100-pin plastic LQFP package, 14 mm x 20 mm · Sleep Mode : ZZ (Enables sleep mode, active high)
