LY625128PL-55LLI – LYONTEK

The LY625128PL-55LLI is a 512K x 8-bit (4 Mbit) CMOS Static Random-Access Memory (SRAM) manufactured by LYONTEK. It features a typical access time of 55ns, indicated by the “-55” in the part number, making it suitable for applications requiring relatively fast data retrieval. The “PL” likely denotes a specific package type, possibly a Plastic Leaded Chip Carrier (PLCC) or similar, requiring further datasheet verification. The “LLI” suffix may indicate a low-power version or a specific lead finish. The “NOPB” marking signifies a lead-free (No Lead) construction, compliant with RoHS standards. The date code “D/C 0809” indicates the part was manufactured in the 9th week of 2008. This SRAM operates on a single 3.3V power supply and offers TTL-compatible inputs and outputs. Further electrical characteristics, such as operating current and standby current, are dependent on the specific datasheet revision.
