MX29LA32xMT/B
FEATURES
32M-BIT [4M x 8/2M x 16] SINGLE VOLTAGE 3V
ONLY FLASH MEMORY
- 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 all
sectors, regardless of sector protect status
- ACC (high voltage) accelerates programming time
for higher throughput during system
SECURITY
• 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
• 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
- Provides a 128-word OTP area for permanent, se-
cure identification
- Can be programmed and locked at factory or by cus-
tomer

- Sector erase time: 0.5s (typ.)
- Effective write buffer word programming time: 22us
- 4 word/8 byte page read buffer
- 16 word/ 32 byte write buffer: reduces programming
time for multiple-word/byte updates
• Low Power Consumption

- Active write current: 50mA(typ.)
- Standby current: 20uA(typ.)
• Minimum 100,000 erase/program cycle
• 20-years data retention
SOFTWARE FEATURES
• Support Common Flash Interface (CFI)
- Flash device parameters stored on the device and
provide the host system to access
• Program Suspend/Resume
- Suspend program operation to read other sectors
• 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
GENERAL DESCRIPTION
The MX29LA32xMT/B is a 32-mega bit Flash memory
organized as 4M bytes of 8 bits or 2M words of 16 bits.
MXIC's Flash memories offer the most cost-effective and
reliable read/write non-volatile random access memory.
The MX29LA32xMT/B is packaged in 48-pin TSOP, 48-
ball CSP, 56-pin TSOP and 64-ball CSP. It is designed
P/N:PM1144
to be reprogrammed and erased in system or in standard
EPROM programmers.
The standard MX29LA32xMT/B offers access time as
fast as 70ns, allowing operation of high-speed micropro-
cessors without wait states. To eliminate bus conten-
tion, the MX29LA32xMT/B has separate chip enable
(CE#) and output enable (OE#) controls.
