Overview

Description

AS4C512M8D4-83BIN is a memory IC from Alliance Memory in the AS4C family. It is a 512 Mbit density, organized with an 8-bit data path (x8) and is a parallel synchronous DRAM device. It uses a standard SDRAM-style interface with CK, CS, RAS, CAS, WE, and DQ signals, and is designed for synchronous operation with typical DRAM timing parameters (latency, tRCD, tRP, tCAS, etc.). The suffix -83BIN denotes the specific speed/packaging bin for this device (a particular lot/variant used in manufacturing) rather than a different technology. Operating voltage is commonly 3.3V (some variants may differ). Applications include embedded systems, consumer electronics, set-top boxes, and other devices needing relatively dense, low-cost DRAM. For exact electrical specs, timing, organization, packaging, and to confirm the correct replacement, refer to the official AS4C512M8D4-83BIN datasheet and marking information from Alliance Memory.

Features

I don’t have the exact datasheet here, but AS4C512M8D4-83BIN is a 512 Mbit NAND flash device. Likely key features:
- Capacity/organization: 512 Mbit total, x8 data I/O (512M x 8)
- Page/OOB: typical 4 KB page with ~128 bytes OOB area
- Interface: parallel NAND, ONFI-compatible
- Planes: multi-plane operation for higher throughput
- Voltage: Vcc in the 2.7–3.6 V range
- Endurance/Retention: around 100k P/E cycles; 10-year data retention (at 25°C)
- ECC: built-in ECC support (host BCH capable) for error correction
- Packaging/variant: packaged in a standard form; suffix “-83BIN” denotes manufacturing/packaging variant
Note: exact specs (page size, planes, ECC strength, and voltage window) can vary by revision. Please refer to the official datasheet for precise numbers.
