The Atmel AT27C2048 is a low-power, high-performance 2,097,152-bit, one-time programmable, read-only memory (OTP EPROM) organized as 128K by 16 bits. It requires a single 5V power supply in normal read mode operation. Any word can be accessed in less than 55 ns, eliminating the need for speed-reducing WAIT states. The x16 organization makes this part ideal for high-performance, 16- and 32-bit microprocessor systems. In read mode, the AT27C2048 typically consumes 15mA. Standby mode supply current is typically less than 10µA.
