Frequently Asked Questions
What is the storage depth and width of the SN74ACT3622-30PQ?
The SN74ACT3622-30PQ is a 256x36 FIFO, meaning it stores 256 words each 36 bits wide, for a total of 9216 bits (approximately 1152 bytes). The 36-bit width allows storage of 32-bit data words plus 4 bits of parity or ECC, supporting data integrity checking in critical applications.
What does the bidirectional FIFO capability mean in the SN74ACT3622-30PQ?
The bidirectional FIFO capability means the device contains two independent FIFO buffers that can be used simultaneously to transfer data in both directions between two ports. This enables full-duplex communication between two processors or subsystems, with each direction independently managed and with mailbox flags for handshaking.
What is the operating speed of the SN74ACT3622-30PQ?
The SN74ACT3622-30PQ operates at a maximum clock frequency of 33.4 MHz with a 30 ns cycle time and 15 ns access time. The -30PQ suffix indicates the 30 ns speed grade variant, allowing reliable clocked operation in synchronous FIFO mode for high-throughput data buffering applications.
What package does the SN74ACT3622-30PQ come in?
The SN74ACT3622-30PQ is housed in a 132-pin PQFP (Plastic Quad Flat Package, JEDEC S-PQFP-G132). This high pin-count package accommodates the wide bidirectional data bus, control signals, and address/status outputs required for the device's dual-port FIFO interface.
