Intel’s 28F001BX-B and 28F001BX-T combine the cost-effectiveness of Intel standard flash memory with

features that simplify write and allow block erase. These devices aid the system designer by combining the

functions of several components into one, making boot block flash an innovative alternative to EPROM and

EEPROM or battery-backed static RAM. Many new and existing designs can take advantage of the

28F001BX’s integration of blocked architecture, automated electrical reprogramming, and standard processor

interface.

The 28F001BX-B and 28F001BX-T are 1,048,576 bit nonvolatile memories organized as 131,072 bytes of

8 bits. They are offered in 32-pin plastic DIP, 32-lead PLCC and 32-lead TSOP packages. Pin assignment

conform to JEDEC standards for byte-wide EPROMs. These devices use an integrated command port and

state machine for simplified block erasure and byte reprogramming. The 28F001BX-T’s block locations pro-

vide compatibility with microprocessors and microcontrollers that boot from high memory, such as Intel’s

MCS -186 family, 80286, i386^TM, i486^TM, i860^TMand 80960CA. With exactly the same memory segmentation,

the 28F001BX-B memory map is tailored for microprocessors and microcontrollers that boot from low memory,

such as Intel’s MCS-51, MCS-196, 80960KX and 80960SX families. All other features are identical, and unless

otherwise noted, the term 28F001BX can refer to either device throughout the remainder of this document.

The boot block section includes a reprogramming write lock out feature to guarantee data integrity. It is

designed to contain secure code which will bring up the system minimally and download code to the other

locations of the 28F001BX. Intel’s 28F001BX employs advanced CMOS circuitry for systems requiring high-

performance access speeds, low power consumption, and immunity to noise. Its access time provides

no-WAIT-state performance for a wide range of microprocessors and microcontrollers. A deep-powerdown

mode lowers power consumption to 0.25 mW typical through V , crucial in laptop computer, handheld instru-

mentation and other low-power applications. The RP power control input also provides absolute data protec-

tion during system powerup or power loss.

Manufactured on Intel’s ETOX process base, the 28F001BX builds on years of EPROM experience to yield the

highest levels of quality, reliability, and cost-effectiveness.

NOTE: The 28F001BN is equivalent to the 28F001BX.
