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:

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

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.

Note:
1. A8=H is recommended for Manufacturing ID check. If a manufacturing ID is read with A8=L, the chip will output a
configuration code 7Fh.
2. A9 = VIDB B is for HV A9 Autoselect mode only. A9 must be ≤ Vcc (CMOS logic level) for Command Autoselect
Mode.
