heeFEATURES
taSGENERAL FEATURES
a• 8,388,608 x 8 byte structure
.D• One hundred twenty-eight Equal Sectors with 64K byte
each
w- Any combination of sectors can be erased with erase
w suspend/resume function
w • Sector Protection/Chip Unprotected
m- Provides sector group protect function to prevent pro
gram or erase operation in the protected sector group
o- Provides chip unprotected function to allow code
.cchanging
- Provides temporary sector group unprotected func-
tion for code changing in previously protected sector
Ugroups
• Secured Silicon Sector
t4- Provides a 128-byte area for code or data that can
be permanently protected.
- Once this sector is protected, it is prohibited to pro-
egram or erase within the sector again.
e• Single Power Supply Operation
- 3.0 to 3.6 volt for read, erase, and program opera-
htions
• Latch-up protected to 250mA from -1V to Vcc + 1V
S• Low Vcc write inhibit is equal to or less than 2.5V
ta• Compatible with JEDEC standard
- Pinout and software compatible to single power sup-
ply Flash
aPERFORMANCE
.D• High Performance
- Fast access time: 90/120ns
- Fast program time: 7us, 42s/chip (typical)
w- Fast erase time: 0.9s/sector, 45s/chip (typical)
• Low Power Consumption
w- Low active read current: 9mA (typical) at 5MHz
- Low standby current: 0.2uA(typ.)
• Minimum 100,000 erase/program cycle
• 20-year 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
• ACC pin
- Accelerates programming time for higher throughput
during system production
PACKAGE
• 48-pin TSOP
• 63-ball CSP
w U.comGENERAL DESCRIPTION
et4The MX29LV065B is a 64-mega bit Flash memory orga-
enized as 8M bytes of 8 bits. MXIC's Flash memories
hoffer the most cost-effective and reliable read/write non-
Svolatile random access memory. The MX29LV065B is
tapackaged in 48-pin TSOP and 63-ball CSP. It is designed
ato be reprogrammed and erased in system or in standard
.DEPROM programmers.
The standard MX29LV065B offers access time as fast
as 90ns, allowing operation of high-speed microproces-
sors without wait states. To eliminate bus contention,
the MX29LV065B has separate chip enable (CE#) and
output enable (OE#) controls.
MXIC's Flash memories augment EPROM functionality
