IDT49C460

  The IDT49C460s are high-speed, low-power, 32-bit Error Detection and Correction Units which generate check bits on a 32-bit data field according to a modified Hamming Code and correct the data word when check bits are supplied. The IDT49C460s are performance-enhanced functional replacements for 32-bit versions of the 2960. When performing a read operation from memory, the IDT49C460s will correct 100% of all single bit errors and will detect all double bit errors and some triple bit errors.
  The IDT49C460s are easily cascadable to 64-bits. Thirtytwo- bit systems use 7 check bits and 64-bit systems use 8
check bits. For both configurations, the error syndrome is made available.
  The IDT49C460s incorporate two built-in diagnostic modes. Both simplify testing by allowing for diagnostic data to be entered into the device and to execute system diagnostics functions.
  They are fabricated using a CMOS technology designed for high-performance and high-reliability. The devices are packaged in a 68-pin ceramic PGA, PLCC and Ceramic Quad Flatpack.
  Military grade product is manufactured in compliance with the latest revision of MIL-STD-883, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
