PRELIMINARY DATA SHEET  
MOS INTEGRATED CIRCUIT  
µ
PD4481162, 4481182, 4481322, 4481362  
8M-BIT ZEROSBTM SRAM  
PIPELINED OPERATION  
Description  
The µPD4481162 is a 524,288-word by 16-bit, the µPD4481182 is a 524,288-word by 18-bit, the µPD4481322 is a  
262,144-word by 32-bit and the µPD4481362 is a 262,144-word by 36-bit ZEROSB static RAM fabricated with  
advanced CMOS technology using full CMOS six-transistor memory cell.  
The µPD4481162, µPD4481182, µPD4481322 and µPD4481362 are optimized to eliminate dead cycles for read to  
write, or write to read transitions. These ZEROSB static RAMs integrate unique synchronous peripheral circuitry, 2-bit  
burst counter and output buffer as well as SRAM core. All input registers are controlled by a positive edge of the  
single clock input (CLK).  
The µPD4481162, µPD4481182, µPD4481322 and µPD4481362 are suitable for applications which require  
synchronous operation, high speed, low voltage, high density and wide bit configuration, such as buffer memory.  
ZZ has to be set LOW at the normal operation. When ZZ is set HIGH, the SRAM enters Power Down State (“Sleep”).  
In the “Sleep” state, the SRAM internal state is preserved. When ZZ is set LOW again, the SRAM resumes normal  
operation.  
The µPD4481162, µPD4481182, µPD4481322 and µPD4481362 are packaged in 100-pin PLASTIC LQFP with a 1.4  
mm package thickness or 165-pin TAPE FBGA for high density and low capacitive loading.  
Features  
• Low voltage core supply (A version : VDD = 3.3 ± 0.165V, C version : VDD = 2.5 ± 0.125V)  
• Synchronous operation  
• 100 percent bus utilization  
• Internally self-timed write control  
• Burst read / write : Interleaved burst and linear burst sequence  
• Fully registered inputs and outputs for pipelined operation  
• All registers triggered off positive clock edge  
• 3.3V or 2.5V LVTTL Compatible : All inputs and outputs  
• Fast clock access time : 3.2 ns (200 MHz), 3.5 ns (167 MHz) , 4.2 ns (133 MHz)  
• Asynchronous output enable : /G  
• Burst sequence selectable : MODE  
• Sleep mode : ZZ (ZZ = Open or Low : Normal operation)  
• Separate byte write enable : /BW1 - /BW4 (µPD4481322 and µPD4481362), /BW1 - /BW2 (µPD4481162 and µPD4481182)  
• Three chip enables for easy depth expansion  
• Common I/O using three state outputs
