Macronix International 

MX29LV640BT/BB

FEATURES

64M-BIT [8M x 8/4M x 16] SINGLE VOLTAGE 3V ONLY

FLASH MEMORY

GENERAL FEATURES

• Single Power Supply Operation

- 2.7 to 3.6 volt for read, erase, and program opera-

tions

• 8,388,608 x 8 / 4,194,304 x 16 switchable

• Sector structure

- 8KB (4KW) x 8 and 64KB(32KW) x 127

• Sector Protection/Chip Unprotect

- Provides sector group protect function to prevent

program or erase operation in the protected sector

group

- Provides chip unprotect function to allow code

changes

- Provides temporary sector group unprotect function

for code changes in previously protected sector groups

• Secured Silicon Sector

- Provides a 128-word area for code or data that can

be permanently protected.

- Once this sector is protected, it is prohibited to pro-

gram or erase within the sector again.

• Latch-up protected to 250mA from -1V to Vcc + 1V

• Low Vcc write inhibit is equal to or less than 1.5V

• Compatible with JEDEC standard

- Pin-out and software compatible to single power sup-

ply Flash

PERFORMANCE

• High Performance

- Fast access time: 90/120ns

- Fast program time: 11us/word, 45s/chip (typical)

- Fast erase time: 0.9s/sector, 45s/chip (typical)

• Low Power Consumption

- Low active read current: 9mA (typical) at 5MHz

- Low standby current: 0.2uA (typ.)

• Minimum 100,000 erase/program cycle

• 10 years data retention

SOFTWARE FEATURES

• Support Common Flash Interface (CFI)

- Flash device parameters stored on the device and

provide the host system to access.

• Erase Suspend/ Erase Resume

- Suspends sector erase operation to read data from

or program data to another sector which is not being

erased

• Status Reply

- Data# polling & Toggle bits provide detection of pro-

gram and erase operation completion

HARDWARE FEATURES

• Ready/Busy (RY/BY#) Output

- Provides a hardware method of detecting program

and erase operation completion

• Hardware Reset (RESET#) Input

- Provides a hardware method to reset the internal

state machine to read mode

• WP#/ACC input

- Write protect (WP#) function allows protection of two

outermost boot sectors, regardless of sector protect

status

- ACC (high voltage) accelerates programming time

for higher throughput during system

PACKAGE

• 48-pin TSOP

• 63-Ball CSP

• All Pb-free devices are RoHS Compliant

GENERAL DESCRIPTION

The MX29LV640BT/BB is a 64-mega bit Flash memory

organized as 8M bytes of 8 bits or 4M words of 16 bits.

MXIC's Flash memories offer the most cost-effective and

reliable read/write non-volatile random access memory.

The MX29LV640BT/BB is packaged in 48-pin TSOP and

63-ball CSP. It is designed to be reprogrammed and

erased in system or in standard EPROM programmers.

The standard MX29LV640BT/BB offers access time as

fast as 90ns, allowing operation of high-speed micropro-

cessors without wait states. To eliminate bus conten-

tion, the MX29LV640BT/BB has separate chip enable

(CE#) and output enable (OE#) controls.

MXIC's Flash memories augment EPROM functionality

with in-circuit electrical erasure and programming. The
