ESMT M52S128168A is a 2.5V power supply LVTTL compatible four-channel synchronous DRAM, supporting 143MHz, 133MHz, 100MHz multiple frequencies
The M52S128168A is a 2M × 16‑bit mobile SDRAM organized as four banks, designed for high‑bandwidth, high‑performance applications. It operates from a 2.5 V supply, is LVTTL compatible, and supports a range of burst lengths, latencies, and special functions such as PASR and TCSR.
Key features include 2.5 V power supply, LVTTL I/O, four‑bank operation, programmable CAS latency (2‑3), burst lengths (1, 2, 4, 8, full page), auto/self‑refresh, 64 ms refresh period, and multiple package options (54‑ball TSOP II and FBGA). The device’s absolute maximum ratings, DC and AC characteristics, and timing parameters are detailed for design integration.
