ply Flash
PERFORMANCE
• High Performance
- Fast access time: 70R/90ns
- Page read time: 25ns
- 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
- Active read current: 18mA(typ.)
- Active write current: 20mA(typ.)
- Standby current: 20uA(typ.)
• Minimum 100,000 erase/program cycle
• 20-year data retention
SOFTWARE FEATURES
• Supports 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
- Suspends sector erase operation to read data/pro-
gram other sectors
• 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 all
sectors, regardless of sector protection settings
- 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
- Through a unique permanent locking scheme, the
device allows the user to permanently lock any ran-
domly selected sector(s) within the memory array
(Please contact Macronix for specifics relating to
this feature - this datasheet does not include any
other information relating to this 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
PACKAGE
• 56-pin TSOP
• 64-ball CSP
•
All Pb-free devices are RoHS Compliant
GENERAL DESCRIPTION
The MX29LA321M H/L 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 MX29LA321M H/L is packaged in 56-pin TSOP and
64-ball CSP. It is designed to be reprogrammed and
erased in system or in standard EPROM programmers.
The standard MX29LA321M H/L offers access time as
fast as 70ns, allowing operation of high-speed micropro-
cessors without wait states. To eliminate bus conten-
tion, the MX29LA321M H/L has separate chip enable
