Intel’s 28F010 CMOS flash memory offers the most cost-effective and reliable alternative for read/write
random access nonvolatile memory. The 28F010 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 28F010 increases
memory flexibility, while contributing to time and cost savings.
The 28F010 is a 1024 kilobit nonvolatile memory organized as 131,072 bytes of 8 bits. Intel’s 28F010 is
offered in 32-pin plastic dip or 32-lead PLCC and 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 12.0V V
PP
supply, the 28F010 performs
100,000 erase and program cycles well within the time limits of the Quick Pulse Programming and Quick Erase
algorithms.
Intel’s 28F010 employs advanced CMOS circuitry for systems requiring high-performance access speeds, low
power consumption, and immunity to noise. Its 65 nanosecond access time provides no-WAIT-state perform-
ance for a wide range of microprocessors and microcontrollers. Maximum standby current of 100
m
A trans-
lates 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

With Intel’s ETOX process base, the 28F010 builds on years of EPROM experience to yield the highest levels
of quality, reliability, and cost-effectiveness.
