36Mb SigmaQuad-II Burst

Preliminary GS8342D08/09/18/36E-333/300/250/200/167 www.DataSheet4U.com 165-Bump BGA Commercial Temp Industrial Temp Features • Simultaneous Read and Write SigmaQuad™ Interface • JEDEC-standard pinout and package • Dual Double Data Rate interface • Byte Write controls sampled at data-in time • Burst of 4 Read and Write • 1.8 V +100/–100 mV core power supply • 1.5 V or 1.8 V HSTL Interface • Pipelined read operation • Fully coherent read and write pipelines • ZQ pin for programmable output drive strength • IEEE 1149.1 JTAG-compliant Boundary Scan • 165-bump, 15 mm x 17 mm, 1 mm bump pitch BGA package • RoHS-compliant 165-bump BGA package available • Pin-compatible with present 9Mb and 18Mb and future 72Mb and 144Mb devices 36Mb SigmaQuad-II Burst of 4 SRAM 167 MHz–333 MHz 1.8 V VDD 1.8 V and 1.5 V I/O Bottom View 165-Bump, 15 mm x 17 mm BGA 1 mm Bump Pitch, 11 x 15 Bump Array C clock inputs. C and C are also independent single-ended clock inputs, not differential inputs. If the C clocks are tied high, the K clocks are routed internally to fire the output registers instead. Because Separate I/O SigmaQuad-II B4 RAMs always transfer data in four packets, A0 and A1 are internally set to 0 for the first read or write transfer, and automatically incremented by 1 for the next transfers. Because the LSBs are tied off internally, the address field of a SigmaQuad-II B4 RAM is always two address pins less than the advertised index depth (e.g., the 2M x 18 has a 512K addressable index).
