X24F032

The X24F064/X24F032/016 is a CMOS SerialFlash Memory Family, internally organized 8K/4K/2K x 8. The X24F032 features a serial interface and software protocol allowing operation on a simple two wire bus.

Device select inputs (S 0 , S 1 , S 2 ) allow up to eight devices to share a common two wire bus.

A Program Protect Register accessed at the highest address location, provides three new programming protection features: Software Programming Protection, Block Lock Protection, and Hardware Programming Protection. The Software Programming Protection of X24F032 feature prevents any nonvolatile writes to the X24F032 until the WEL bit in the program protect register is set. The Block Lock TM Protection feature allows the user to individually protect four blocks of the array by programming two bits in the programming protect register. The Programmable Hardware Program Protect of X24F032 feature allows the user to install each device with PP tied to V CC , program the entire memory array in place, and then enable the hardware programming protection by programming a PPEN bit in the program protect register. After this, selected blocks of the array, including the program protect register itself, are permanently protected from being programmed.
