SN74ABT3612 64 x 36 x 2 双向同步 FIFO 存储器
The SN74ABT3612
is a high-speed, low-power BiCMOS bidirectional clocked FIFO memory. It supports clock frequencies up to 67 MHz and has read access times as fast as 10 ns. Two independent 64 × 36 dual-port SRAM FIFOs in this device buffer data in opposite directions. Each FIFO has flags to indicate empty and full conditions and two programmable flags (almost-full and almost-empty) to indicate when a selected number of words is stored in memory. Communication between each port can bypass the FIFOs via two 36-bit mailbox registers. Each mailbox register has a flag to signal when new mail has been stored. Parity is checked passively on each port and can be ignored if not desired. Parity generation can be selected for data read from each port.
