The AS4C16M16SA-6BIN from Alliance Memory is a 256 Mbit single-data-rate synchronous DRAM organised as 16 M x 16, supplied in a 54-pin TFBGA. It runs at up to 166 MHz with a 6 ns access time over a parallel interface, from a 3.0 V to 3.6 V supply. The industrial temperature grade extends the operating range from -40C to +85C, which is the distinguishing feature of this version. The AS4C16M16SA-6BIN is RoHS compliant, lead-free, MSL 3, and supplied in trays of 348 pieces.

A x16 organisation means the whole 16-bit data bus is served by one device, so this part is specified where a design needs a 16-bit memory interface without pairing two x8 chips: industrial controllers, HMI and display panels, printers, networking and telecom line cards, medical instruments and automotive modules. Alliance Memory positions itself as a long-lifecycle supplier, so parts like this are frequently used to sustain products whose original SDRAM has gone end-of-life. The -40C to +85C industrial grade is the reason to choose this suffix over a commercial equivalent. Buyers are embedded designers and obsolescence-management teams keeping legacy SDR-interface platforms in production.
