The SN74ACT3631-30PCB is a high-speed, low-power CMOS clocked FIFO memory designed for buffering data between two ports. It supports clock frequencies up to 67 MHz and offers fast read access times as low as 11 ns. The device features a 512 words by 36 bits dual-port SRAM FIFO.
Key features include synchronous operation, retransmit capability allowing previously read data to be accessed again, and mailbox registers for inter-port communication. Programmable almost-full and almost-empty flags provide flexible buffer management. The input-ready and almost-full flags are synchronized by CLKA, while output-ready and almost-empty flags are synchronized by CLKB.
This FIFO memory operates over a temperature range of 0°C to 70°C and requires a supply voltage between 4.5V and 5.5V, drawing a maximum of 400µA. It is available in a 120-pin HLQFP package suitable for surface mounting.
Expansion is possible in both word depth and width by paralleling multiple devices. The SN74ACT3631-30PCB is pin-to-pin compatible with the SN74ACT3641 and SN74ACT3651.
