ICE27LC010
1- Megabit(128KX8) OTP EPROM
Description
The ICE27LC010 is a low-power, high-performance 1M(1,048,576) bit one-time programmable read only
memory (OTP EPROM) organized as 128K by 8 bits. It is single 3.3V power supply in normal read mode
operation. Any byte can be accessed in less than 100 ns. The ICE27LC010 typically consumes 15mA ,
standby mode supply current typically 1µA. Two lines control (CE, OE) to give designers the flexibility to
prevent bus contention. Programming time is typically only 100
µs/byte.
The Integrated Product Identification
Code electronically identifies the device and manufacturer. This feature is used by industry standard
programming equipment to select the proper programming algorithms and voltages.
