FEATURES
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
