IDT71216S12PF规格书详情
DESCRIPTION:
The IDT71216 is a 245,760-bit Cache Tag StaticRAM, organized 16K x 15 and designed to support PowerPC and other RISC processors at bus speeds up to 66MHz. There are twelve common I/O TAG bits, with the remaining three bits used as status bits. A 12-bit comparator is on-chip to allow fast comparison of the twelve stored TAG bits and the current Tag input data. An active HIGH MATCH output is generated when these two groups of data are the same for a given address.
FEATURES:
• 16K x 15 Configuration
– 12 TAG Bits
– 3 Separate I/O Status Bits (Valid, Dirty, Write Through)
• Match output uses Valid bit to qualify MATCH output
• High-Speed Address-to-Match comparison times
– 8/9/10/12ns over commercial temperature range
• TA circuitry included inside the Cache-Tag for highest speed operation
• Asynchronous Read/Match operation with Synchronous Write and Reset operation
• Separate WE for the TAG bits and the Status bits
• Separate OE for the TAG bits, the Status bits, and TA
• Synchronous RESET pin for invalidation of all Tag entries
• Dual Chip selects for easy depth expansion with no performance degredation
• I/O pins both 5V TTL and 3.3V LVTTL compatible with VCCQ pins
• PWRDN pin to place device in low-power mode
• Packaged in a 80-pin Thin Plastic Quad Flat Pack (TQFP)
