ASAHI KASEI [AK93C45A/55A/65A/75A] DAM01E-01 is a 1K/2K/4K/8K-bit serial CMOS EEPROM with wide operating voltage range and low power consumption. It is ideal for low density data storage and offers high reliability and automation features.
The AK93C45A/55A/65A/75A series are low‑density serial CMOS EEPROMs offering 1 K to 8 K bits of non‑volatile memory in 8‑pin SOP/TSSOP packages. They operate over a wide voltage range (1.8 V – 5.5 V) and temperature range (‑40 °C – 85 °C), with low power consumption and high reliability.
The devices use a simple 4‑wire serial interface (CS, SK, DI, DO) and support four basic instructions (READ, WRITE, EWEN, EWDS). Features include automatic address increment, busy/ready status signaling, software‑controlled write protection, and endurance of 100 k cycles with a 10‑year data‑retention guarantee.
