GENERAL DESCRIPTION

The MX29LA129M H/L is a 128-mega bit Flash memory organized as 16M bytes of 8 bits or 8M words of 16 bits. MXICs Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LA129M H/L is packaged in 56-pin TSOP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.

FEATURES

GENERAL FEATURES

? Single Power Supply Operation

- 2.7 to 3.6 volt for read, erase, and program operations

? Configuration

PERFORMANCE

? High Performance

- Fast access time: 90R/100ns

- 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 write current: 20mA(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/Program Resume

- Suspend program operation to read other sectors

? Erase Suspend/ Erase Resume

- Suspends sector erase operation to read data/program other sectors

? 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 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 program or erase operation in the protected sector group

- Provides chip unprotect function to allow code changes

- 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 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

PACKAGE

? 56-pin TSOP
