The AT27BV010 is a high-performance, low-power, low-voltage 1,048,576-bit one- time programmable read-only memory (OTP EPROM) organized as 128K by 8 bits. It requires only one supply in the range of 2.7V to 3.6V in normal read mode operation, making it ideal for fast, portable systems using either regulated or unregulated battery power. Atmel’s innovative design techniques provide fast speeds that rival 5V parts while keeping the low power consumption of a 3V supply. At VCC = 2.7V, any byte can be accessed in less than 90 ns. With a typical power draw of only 18 mW at 5 MHz and VCC = 3V, the AT27BV010 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3V.
The AT27BV010 is a 1‑Megabit one‑time programmable EPROM that operates from 2.7 V to 3.6 V (or standard 5 V + 10%). It offers fast read access, low standby current, and high reliability features such as 2 kV ESD protection and 200 mA latchup immunity.
