One-Time Programmable Memory from the Market Leader
A long-time market leader in EPROM technology, Atmel offers 5V, 3V and Battery-Voltage™ (2.7V) EPROMs for a variety of applications. Atmel has one of the broadest range of one-time programmable (OTP) EPROMs, with densities ranging from 256-Kbits to 8-Mbits, speeds as fast as 45ns, and package options that including PDIP, PLCC, SOIC, TSOP, and TSSOP. The devices are widely used for embedded program code storage in applications such as: cordless phones, pagers, video game players, printers, modems, graphics cards, instrumentation, automotive, medical devices, telecommunications, networking, industrial control equipment, and hard disk drives.
Key Features
- Lower power — The Atmel innovative design techniques provide fast speeds that rival 5V devices while retaining the low power consumption of a 3V power supply.
- Standard packages — The devices are available in industry-standard JEDEC-approved OTP plastic PLCC, TSOP, and VSOP packages.
- Two-line control — All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention.
- Additional features — The AT27Cxxx and AT27LVxxx series both have additional features to ensure high quality and efficient product use, including Rapid Programming Algorithm and Integrated Product Identification Code.
