Samsung K4S281633D-RL(N) 8Mx16 SDRAM 54CSP Datasheet
The Samsung K4S281633D-RL(N) is an 8M‑by‑16‑bit CMOS SDRAM offered in a 54‑ball CSP package. It supports 3.0 V and 3.3 V power supplies, LVTTL‑compatible multiplexed addresses, four‑bank operation, and programmable CAS latency (1‑3) and burst lengths (1, 2, 4, 8, full page). The device is designed for high‑performance memory systems with a maximum frequency of 133 MHz (CL = 3).
The datasheet provides detailed ordering information, package dimensions, absolute maximum ratings, DC and AC operating conditions, timing parameters, and mode‑register programming. It also includes a simplified truth table for command encoding and a recommended power‑up sequence.
