IDT71215S12PF

The IDT71215S12PF is a designed as 245,760 bit cache tag staticRAM, organized 16K x15 and designed to support the pentium and other Intel 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.

The features of the IDT71215S12PF. (1)16K x15 configuration which means 12 TAG bits and 3 separate I/O status bits (valid, dirty, write through). (2)Match output uses valid bit to qualify match output. (3)High-speed address-to-match comparison times which means 8/9/10/12ns over commercial temperature range. (4)BRDY circuitry included inside the cache-tag for highest speed operation. (5)Asynchronous read/match operation with synchronous write and reset operation. (6)Separate WE for the TAG bits and the status bits. (7)Separate OE for the TAG bits, the status bits, and BRDY. (8)Synchronous RESET pin for invalidation of all tag entries. (9)Dual chip selects for easy depth expansion with no performance degredation. (10)I/O pins both 5V TTL and 3.3V LVTTL compatible with VCCQ pins. And so on.

Some absolute maximum ratings of the IDT71215S12PF have been concluded into several points as follow. (1)Its terminal voltage with respect to GND would be from -0.5V to 7.0V. (2)Its operating temperature range would be from 0°C to 70°C. (3)Its temperature under bias would be from -65°C to 135°C. (4)Its storage temperature range would be from -65°C to 150°C. (5)Its power dissipation would be 1.7W. (6)Its DC output current would be 20mA. (7)Its supply voltage would be min 4.75V and typ 5.0V and max 5.25V. (8)Its 5V output buffers would be min 4.75V and typ 5V and max 5.25V. (9)Its 3.3V output buffers would be min 3.0V and typ 3.3V and max 3.6V. And so on. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.
