GENERAL DESCRIPTION

The EN29LV800 is an 8-Megabit, electrically erasable, read/write non-volatile flash memory, organized as 1,048,576 bytes or 524,288 words. Any byte can be programmed typically in 10µs. The EN29LV800 features 3.0V voltage read and write operation, with access times as fast as 55ns to eliminate the need for WAIT states in high-performance microprocessor systems.

FEATURES

• Single power supply operation

- Full voltage range: 2.7-3.6 volt read and write operations for battery-powered applications.

- Regulated voltage range: 3.0-3.6 volt read and write operations and for compatibility with high performance 3.3 volt microprocessors.

• Manufactured on 0.28 µm process technology

• High performance

- Access times as fast as 70 ns

• Low power consumption (typical values at 5 MHz)

- 7 mA typical active read current

- 15 mA typical program/erase current

- 1 µA typical standby current (standard access time to active mode)

• Flexible Sector Architecture:

- One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and fifteen 64 Kbyte sectors (byte mode)

- One 8 Kword, two 4 Kword, one 16 Kword and fifteen 32 Kword sectors (word mode)

- Supports full chip erase

- Individual sector erase supported

- Sector protection: Hardware locking of sectors to prevent program or erase operations within individual sectors Additionally, temporary Sector Group Unprotect allows code changes in previously locked sectors.

• High performance program/erase speed

- Byte/Word program time: 8µs typical

- Sector erase time: 500ms typical
