Description
AS4C4M16SA-6TIN is a synchronous DRAM (SDRAM) device from Alliance Memory in the AS4C4M16SA family. It typically features a 4M x 16-bit organization (about 64 Mbits total) with a 3.3 V supply and a -6 speed grade. The device uses a multiplexed address bus and a synchronous, burst-oriented interface compatible with common SDRAM controllers, supporting configurable burst lengths and self-refresh, plus pipeline read/write capabilities tied to the system clock.
The -TIN suffix denotes a packaging/order option (for example, a tape-in/lead-free variant or similar option set). Exact packaging, temperature grade, and RoHS status vary by supplier, so consult the data sheet for the precise package, voltage, and timing specifications (CAS latency, tRP, tRCD, tRFC, etc.).
Use: suitable for memory expansion in embedded systems, microprocessors/SoCs, graphics buffers, and other applications needing moderate capacity with fast random access. For detailed electrical/timing diagrams, pinout, power, and thermal specs, refer to the official Alliance Memory datasheet.
