X24F016

The X24F064/032/X24F016 is a CMOS SerialFlash Memory Family, internally organized 8K/4K/2K x 8. The family 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.

The X24F016 is 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 X24F016 feature prevents any nonvolatile writes to the device 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 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 of X24F016, are permanently protected from being programmed.
