The Microchip Technology AT27C2048-70VI is a high-performance, low-power 2,097,152-bit One-Time Programmable Read-Only Memory (OTP EPROM). It is organized as 128K by 16 bits, making it suitable for high-performance 16 and 32-bit microprocessor systems.
This device operates from a single 5V power supply with a ±10% tolerance and offers a fast read access time of 70 ns, eliminating the need for speed-reducing WAIT states. It features low power CMOS operation with a maximum active current of 35 mA at 5 MHz and a maximum standby current of 100 µA.
The AT27C2048-70VI is available in JEDEC standard packages, including the 40-lead VSOP (10 mm x 14 mm), 40-lead PDIP, and 44-lead PLCC. It utilizes two-line control (CE, OE) to prevent bus contention in high-speed systems. The device also incorporates a Rapid™ Programming Algorithm for efficient programming, typically 50 µs per word, and offers 2,000V ESD protection and 200 mA latchup immunity for high reliability.
This OTP EPROM is a direct upgrade from 512K-bit and 1M-bit EPROMs (AT27C516 and AT27C1024). It is designed for applications requiring reliable firmware storage and access without the delays associated with mass storage media.
