GENERAL DESCRIPTION

The MX29LV640BU is a 64-mega bit Flash memory or-

ganized as 4M bytes of 16 bits. MXIC's Flash memories

offer the most cost-effective and reliable read/write non-

volatile random access memory. The MX29LV640BU 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.

P/N:PM1081

word each

- Any combination of sectors can be erased with erase

suspend/resume function

- 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

- 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.

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

tions

- Pinout and software compatible to single power sup-

ply Flash

- Access time: 90/120ns

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

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

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

- Low standby current: 0.2uA(typ.)

SOFTWARE FEATURES

• Support Common Flash Interface (CFI)

• Erase Suspend/ Erase Resume

• Status Reply

HARDWARE FEATURES

• Ready/Busy (RY/BY#) Output

• Hardware Reset (RESET#) Input

• ACC input pin

• WP# pin

PACKAGE

• 48-pin TSOP

• 63-ball CSP

The standard MX29LV640BU offers access time as fast

as 90ns, allowing operation of high-speed microproces-

sors without wait states. To eliminate bus contention,

the MX29LV640BU has separate chip enable (CE#) and

output enable (OE#) controls.

MXIC's Flash memories augment EPROM functionality

- Flash device parameters stored on the device and

provide the host system to access.

- Suspends sector erase operation to read data from

or program data to another sector which is not being

erased

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

gram and erase operation completion

- Provides a hardware method of detecting program

and erase operation completion

- Provides a hardware method to reset the internal

state machine to read mode

- Provides accelerated program capability

- At V

sector protection/unprotected status

- At V
