It provides 18 Kbit of elastic buffering for data-flow applications where the read and write clocks are not synchronized — no external clock or PLL required, just read and write strobes. Typical uses include printer buffers, serial data queues, and rate-matching between peripherals and a host bus in commercial-temperature (0°C to 70°C) equipment such as office automation and telecom line cards. ## Retransmit capability and expansion The retransmit capability allows the FIFO to re-read data from a reset pointer without clearing the entire buffer — useful in retry protocols or data-replay loops. Depth and width expansion are supported, so the part can be cascaded for larger buffers. Note that programmable flags and FWFT (First-Word Fall-Through) are not supported; the flag set is fixed to empty/full/half-full. ## Package and temperature — legacy through-hole fit The 28-pin DIP (0.300\", 7.62 mm) through-hole package suits boards with DIP sockets or wave soldering. ## Lifecycle and sourcing This part is listed as Active in its lifecycle status, meaning AMD continues to manufacture it. No end-of-life notice is in effect. The AM7203A-50RC is RoHS non-compliant (lead-bearing), so verify your assembly process if RoHS exemption is required. Sourced through independent distribution and quoted to order against an RFQ; availability and current pricing are confirmed at quote time.","metaTitle":"AM7203A-50RC Asynchronous FIFO, 18K (2Kx9), 50ns, 15.3MHz","metaDescription":"AM7203A-50RC asynchronous FIFO from AMD. 18K (2K x 9) memory, 50 ns access time, 15.3 MHz data rate, 28-DIP package, commercial temp.
