ply Flash
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 all
sectors, regardless of sector protection settings
- ACC (high voltage) accelerates programming time
for higher throughput during system
PERFORMANCE
• High Performance
- Fast access time: 90R/100ns
- Page read time:25ns
SECURITY
- Sector erase time: 0.5s (typ.)
- 4 word/8 byte page read buffer
- 16 word/ 32 byte write buffer:reduces programming
time for multiple-word/byte updates
• Low Power Consumption
• Sector Protection/Chip Unprotect
- Provides sector group protect function to prevent pro-
gram or erase operation in the protected sector group
- Provides chip unprotect function to allow code
changes
- Active read current: 18mA(typ.)
- Active write current: 20mA(typ.)
- Standby current: 20uA(typ.)
• Minimum 100,000 erase/program cycle
• 20-years data retention
- Provides temporary sector group unprotect function
for code changes in previously protected sector groups
• Sector Permanent Lock
- A unique lock bit feature allows the content to be
permanently locked
(Please contact Macronix sales for specific infor-
mation regarding this permanent lock feature)
• Secured Silicon Sector
SOFTWARE FEATURES
• Support Common Flash Interface (CFI)
- Flash device parameters stored on the device and
provide the host system to access.
• Program Suspend/Program Resume
- Suspend program operation to read other sectors
• Erase Suspend/ Erase Resume
- Provides a 128-word OTP area for permanent, se-
cure identification
- Can be programmed and locked at factory or by cus-
tomer
- Suspends sector erase operation to read data/pro-
gram other sectors
PACKAGE
• 56-pinTSOP
GENERAL DESCRIPTION
The MX29LA128MT/B is a 128-mega bit Flash memory
organized as 16M bytes of 8 bits or 8M words of 16 bits.
MXIC's Flash memories offer the most cost-effective and
reliable read/write non-volatile random access memory.
The MX29LA128MT/B is packaged in 56-pinTSOP. It is
designed to be reprogrammed and erased in system or in
standard EPROM programmers.
The standard MX29LA128M T/B offers access time as
fast as 90ns, allowing operation of high-speed micropro-
cessors without wait states. To eliminate bus conten-
tion, the MX29LA128M T/B has separate chip enable
(CE#) and output enable (OE#) controls.
MXIC's Flash memories augment EPROM functionality
