MOS INTEGRATED CIRCUIT µPD4481162, 4481182, 4481322, 4481362 8M-BIT ZEROSBTM SRAM PIPELINED OPERATION Document No. M15562EJ3V0DS00 (3rd edition) Date Published December 2002 NS CP(K) Printed in Japan DATA SHEET The mark shows major revised points. 2001 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 for high density and low capacitive loading. Features • Low voltage core supply : VDD = 3.3 ± 0.165 V (-A44, -A50, -A60, -A75, -A44Y, -A50Y, -A60Y, -A75Y) VDD = 2.5 ± 0.125 V (-C60, -C75, -C60Y, -C75Y) • Synchronous operation • Operating temperature : TA = 0 to 70 °C (-A44, -A50, -A60, -A75, -C60, -C75) TA = −40 to +85 °C (-A44Y, -A50Y, -A60Y, -A75Y, -C60Y, -C75Y) • 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 : 2.8 ns (225 MHz), 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 to /BW4 ( µPD4481322 and µPD4481362) /BW1 and /BW2 ( µPD4481162 and µPD4481182) • Three chip enables for easy depth expansion • Common I/O using three state outputs |
