EN29LV320

32 Megabit (4096K x 8-bit / 2048K x 16-bit) Flash Memory

Boot Sector Flash Memory, CMOS 3.0 Volt-only

FEATURES

• Single power supply operation

- Full voltage range: 2.7 to 3.6 volts read and

write operations

• High performance

- Access times as fast as 70 ns

• Low power consumption (typical values at 5

MHz)

- 9 mA typical active read current

- 20 mA typical program/erase current

- Less than 1 µA current in standby or automatic

sleep mode.

• Flexible Sector Architecture:

- Eight 8-Kbyte sectors, sixty-three 64k-byte

sectors.

- 8-Kbyte sectors for Top or Bottom boot.

- Sector/Sector Group 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

- Word program time: 8µs typical

- Sector erase time: 500ms typical

- Chip erase time: 70s typical

• JEDEC Standard compatible

• Standard DATA# polling and toggle bits

feature

• Unlock Bypass Program command supported

• Erase Suspend / Resume modes:

Read and program another Sector during

Erase Suspend Mode

• Support JEDEC Common Flash Interface

(CFI).

• Low Vcc write inhibit < 2.5V

• Minimum 100K program/erase endurance

cycles.

• RESET# hardware reset pin

- Hardware method to reset the device to read

mode.

• WP#/ACC input pin

- Write Protect (WP#) function allows

protection of outermost two boot sectors,

regardless of sector protect status

- Acceleration (ACC) function provides

accelerated program times

• Package Options

- 48-pin TSOP (Type 1)

- 48 ball 6mm x 8mm FBGA

• Commercial and Industrial Temperature

Range.

GENERAL DESCRIPTION

The EN29LV320 is a 32-Megabit, electrically erasable, read/write non-volatile flash memory, organized

as 4,194,304 bytes or 2.097,152 words. Any word can be programmed typically in 8µs. The

EN29LV320 features 3.0V voltage read and write operation, with access times as fast as 70ns to

eliminate the need for WAIT states in high-performance microprocessor systems.

The EN29LV320 has separate Output Enable (OE#), Chip Enable (CE#), and Write Enable (WE#)

controls, which eliminate bus contention issues. This device is designed to allow either single Sector or

full Chip erase operation, where each Sector can be individually protected against program/erase

operations or temporarily unprotected to erase or program. The device can sustain a minimum of 100K

program/erase cycles on each Sector.
