Intel’s 28F020 CMOS flash memory offers the most cost-effective and reliable alternative for read/write

random access nonvolatile memory. The 28F020 adds electrical chip-erasure and reprogramming to familiar

EPROM technology. Memory contents can be rewritten: in a test socket; in a PROM-programmer socket; on-

board during subassembly test; in-system during final test; and in-system after sale. The 28F020 increases

memory flexibility, while contributing to time and cost savings.

The 28F020 is a 2048-kilobit nonvolatile memory organized as 262,144 bytes of eight bits. Intel’s 28F020 is

offered in 32-pin plastic DIP, 32-lead PLCC, and 32-lead TSOP packages. Pin assignments conform to

JEDEC standards for byte-wide EPROMs.

Extended erase and program cycling capability is designed into Intel’s ETOX™ (EPROM Tunnel Oxide)

process technology. Advanced oxide processing, an optimized tunneling structure, and lower electric field

combine to extend reliable cycling beyond that of traditional EEPROMs. With the 12.0 V V

supply, the

28F020 performs 100,000 erase and program cycles—well within the time limits of the quick-pulse

programming and quick-erase algorithms.

Intel’s 28F020 employs advanced CMOS circuitry for systems requiring high-performance access speeds,

low power consumption, and immunity to noise. Its 90 ns access time provides zero wait-state performance

for a wide range of microprocessors and microcontrollers. Maximum standby current of 100 µA translates

into power savings when the device is deselected. Finally, the highest degree of latch-up protection is

achieved through Intel’s unique EPI processing. Prevention of latch-up is provided for stresses up to 100 mA

on address and data pins, from –1 V to V

+ 1 V.

With Intel’s ETOX process technology base, the 28F020 builds on years of EPROM experience to yield the

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