The AT27C010 is a low-power, high-performance 1,048,576-bit one-time programmable read-only memory (OTP EPROM) organized as 128K by 8 bits.
The AT27C010 is a 1‑Megabit (128 K × 8) one‑time programmable EPROM offering fast 45 ns read access and low power consumption (8 mA in read, <10 µA standby). It operates from a single 5 V supply and is available in 32‑lead PDIP, PLCC, and TSOP packages.
The device includes a rapid programming algorithm (≈100 µs/Byte), integrated product identification code, and robust protection features such as 2000 V ESD and 200 mA latchup immunity. Detailed electrical specifications, pin configurations, and programming waveforms are provided for system designers.
