... Suspends an erase operation to read data from, or program data to, another sector that is not being erased, GENERAL DESCRIPTION The MX29F040C is a 4-mega bit Flash memory orga- nized 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 MX29F040C is packaged in 32-pin PLCC, TSOP, PDIP ...

... However, multiplexing high voltage onto address lines is not generally desired system design prac- tice. The MX29F040C contains a Silicon-ID-Read operation to supplement traditional PROM programming methodol- ogy. The operation is initiated by writing the read silicon ID command sequence into the command register. Fol- lowing the command write, a read cycle with A1=VIL,A0=VIL retrieves the manufacturer code of C2H ...

P/N:PM1201 MX29F040C (no erase verification command is required). Sector erase is a six-bus cycle operation. There are two "unlock" write cycles. These are followed by writing the set-up com- mand 80H. Two more " ...

... Q7 and Q6 are equivalent to data written to these two bits, at which time the device returns to the Read mode (no program verify command is required). DATA# POLLING-Q7 The MX29F040C also features Data# Polling as a method to indicate to the host system that the Automatic Pro- gram or Erase algorithms are either in progress or com- pleted. ...

... Please note that this is not a device failure condition since the device was incorrectly used. DATA PROTECTION The MX29F040C is designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transi- tion.
