Description
The IDT72275/72285 are exceptionally deep, high speed, CMOS First-In-First-Out (FIFO) memories with clocked read and write controls. These FIFOs offer numerous improvements over previous SuperSync FIFOs, including the following: - The limitation of the frequency of one clock input with respect to the other has been removed.
Key Features
- Pin-compatible with the IDT72255LA/72265LA SuperSync FIFOs
- 10ns read/write cycle time (6.5ns access time)
- Fixed, low first word data latency time
- Auto power down minimizes standby power consumption
- Master Reset clears entire FIFO
- Partial Reset clears data, but retains programmable settings
- Retransmit operation with fixed, low first word data latency time
- Empty, Full and Half-Full flags signal FIFO status
- Programmable Almost-Empty and Almost-Full flags, each flag can default to one of two preselected offsets
- Program partial flags by either serial or parallel means
