MX29LA321DLXCI-70G

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. MXICs 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 to be reprogrammed and erased in system or in standard EPROM programmers.

FEATURES

GENERAL FEATURES

PERFORMANCE

• High Performance
- Fast access time: 70R/90ns
- Page read time: 25ns
- 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

- 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
- Data# polling & Toggle bits provide detection of program 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 program 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 information regarding this permanent lock feature)
• Secured Silicon Sector
- Provides a 128-word OTP area for permanent, secure identification
- Can be programmed and locked at factory or by customer
