AS4C16M32MD1-5BCN

AS4C16M32MD1-5BCN is a high-density memory device from Alliance Memory (AS4C family). It provides 16M × 32-bit organization, i.e., 512 Mbits total storage, with a wide 32-bit data path for parallel access. Used as external RAM in embedded systems, microcontrollers, or SoCs needing a large, wide-memory interface. The “-5” indicates the speed grade, and “-BCN” encodes packaging and temperature rating (industrial options are common). It typically operates at standard memory voltages (often around 3.3V) and is offered in a surface-mount package suitable for consumer and industrial apps. Like other parallel memory devices, it requires a memory controller to manage addressing, timing, and (if applicable) refresh. For exact electrical specs, timing parameters, pinout, and operating conditions, consult the official datasheet for AS4C16M32MD1-5BCN.

Equivalents depend on the exact device type (AS4C16M32MD1 is Alliance Memory 16M x 32 organization; speed grade and voltage vary). To give direct cross references, please confirm:
1) memory type (PSRAM or SDRAM),
2) operating voltage (e.g., 3.3V or 1.8V),
3) package,
4) acceptable manufacturers (Micron, ISSI, Winbond, etc.).
Once confirmed, I’ll provide cross-listed part numbers.

AS4C16M32MD1-5BCN features (concise):
