Manufacturer ISSI
Manufacturer Part Number IS42S16320F-7TLI
Description IC SDRAM 512MBIT 143MHZ 54TSOP
Stock Code W017033

ISSI’s 512Mb Synchronous DRAM achieves high-speed data transfer using pipeline architecture. All inputs and outputs signals refer to the rising edge of the clock input.

  • Clock frequency: 200, 166, 143 MHz
  • Fully synchronous; all signals referenced to a positive clock edge
  • Internal bank for hiding row access/precharge
  • Power supply: Vdd/Vddq = 2.3V-3.6V
  • IS42/45SxxxxxF – Vdd/Vddq = 3.3V
  • IS42/45RxxxxxF – Vdd/Vddq = 2.5
  • LVTTL interface
  • Programmable burst length – (1, 2, 4, 8, full page)
  • Programmable burst sequence: Sequential/Interleave
  • Auto Refresh (CBR)
  • Self Refresh
  • 8K refresh cycles every 64 ms
  • Random column address every clock cycle
  • Programmable CAS latency (2, 3 clocks)
  • Burst read/write and burst read/single write operations capability
  • Burst termination by burst stop and precharge command
  • Packages: x8/x16: 54-pin TSOP-II, 54-ball TF-BGA (x16 only)
  • Temperature Range: Commercial (0o C to +70o C) Industrial (-40o C to +85o C) Automotive, A1 (-40o C to +85o C) Automotive, A2 (-40o C to +105o C)
