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 eight 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 12.0 V VPP 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 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 VCC + 1 V.
With Intel's ETOX process technology base, the 28F010 builds on years of EPROM experience to yield the highest levels of quality, reliability, and cost-effectiveness.
