IS42S16100E IS45S16100E 512K Words x 16 Bits x 2 Banks JUNE 2010 16Mb SYNCHRONOUS DYNAMIC RAM FEATURES DESCRIPTION Clock frequency: 200, 166, 143 MHz ISSI s 16Mb Synchronous DRAM IS42/4516100E is Fully synchronous all signals referenced to a organized as a 524,288-word x 16-bit x 2-bank for positive clock edge improved perfor mance. The synchronous DRAMs achieve high-speed data transfer using pipeline Two banks can be operated simultaneously and architecture. All inputs and outputs signals refer to the independently rising edge of the clock input. Dual inter nal bank controlled by A11 (bank select) Single 3.3V power supply LVTTL interface Programmable burst length (1, 2, 4, 8, full page) Programmable burst sequence: Sequential/Interleave 2048 refresh cycles ever y 32ms (Com, Ind, A1 grade) or 16ms (A2 grade) Random column address ever y clock cycle Programmable CAS latency (2, 3 clocks) Burst read/wr ite and burst read/single wr ite operations capability Burst ter mination by burst stop and precharge command Byte controlled by LDQM and UDQM Packages: 400-mil 50-pin TSOP-II and 60-ball TF-BGA Temperature Grades: o o Commercial (0 C to +70 C) o o Industr ial (-40 C to +85 C) o o Automotive A1 (-40 C to +85 C) o o Automotive A2 (-40 C to +105 C) Copyright 2010 Integrated Silicon Solution, Inc.
