Accepted after primary-datasheet review: both exact order codes are 128 Kbit, 8-lead SOIC/SOP 150 mil, 64-byte page, two-byte word address, 1.7-5.5 V and -40 to +85 °C. Both use 1010b + A2/A1/A0 and a high-active write inhibit on pin 7. PUYA additionally provides transparent ECC, an identification page and a 128-bit serial number. HuluIC has no exact P24C128H-SSH-MIR stock record, so no stock or price claim is made. Document review only; not bench, reliability or production qualified.
