GENERAL DESCRIPTION
The MX29LV004T/B is a 4-mega bit Flash memory or ganized as 512K bytes of 8 bits. MXIC's Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV004T/B is packaged in 40-pin TSOP and 32-pin PLCC. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.

FEATURES
• Extended single - supply voltage range 2.7V to 3.6V
• 524,288 x 8
• Single power supply operation
   - 3.0V only operation for read, erase and program operation

• Low power consumption
   - 20mA maximum active current
   - 0.2uA typical standby current
• Command register architecture
   - Byte Programming (9us typical)
   - Sector Erase (Sector structure 16K-Byte x 1, 8K-Byte x 2, 32K-Byte x1, and 64K-Byte x7)
• Auto Erase (chip & sector) and Auto Program
   - Automatically erase any combination of sectors with Erase Suspend capability.
   - Automatically program and verify data at specified address
• Erase suspend/Erase Resume
   - Suspends sector erase operation to read data from, or program data to, any sector that is not being erased, then resumes the erase.
• Status Reply
   - Data polling & Toggle bit for detection of program and erase operation completion.
• Ready/Busy pin (RY/BY)
   - Provides a hardware method of detecting program or erase operation completion.
• Sector protection
   - Hardware method to disable any combination of sectors from program or erase operations
   - Tempoary sector unprotect allows code changes in previously locked sectors.
