Intel’s 28F008SA 8-Mbit FlashFileTM Memory is the highest density nonvolatile read/write solution for sol-
id-state storage. The 28F008SA’s extended cycling, symmetrically blocked architecture, fast access time,
write automation and low power consumption provide a more reliable, lower power, lighter weight and higher
performance alternative to traditional rotating disk technology. The 28F008SA brings new capabilities to porta-
ble computing. Application and operating system software stored in resident flash memory arrays provide
instant-on, rapid execute-in-place and protection from obsolescence through in-system software updates.
Resident software also extends system battery life and increases reliability by reducing disk drive accesses.
For high density data acquisition applications, the 28F008SA offers a more cost-effective and reliable alterna-
tive to SRAM and battery. Traditional high density embedded applications, such as telecommunications, can
take advantage of the 28F008SA’s nonvolatility, blocking and minimal system code requirements for flexible
firmware and modular software designs.
The 28F008SA is offered in 40-lead TSOP (standard and reverse) and 44-lead PSOP packages. Pin assign-
ments simplify board layout when integrating multiple devices in a flash memory array or subsystem. This
device uses an integrated Command User Interface and state machine for simplified block erasure and byte
write. The 28F008SA memory map consists of 16 separately erasable 64-Kbyte blocks.
Intel’s 28F008SA employs advanced CMOS circuitry for systems requiring low power consumption and noise
immunity. Its 85 ns access time provides superior performance when compared with magnetic storage media.
A deep powerdown mode lowers power consumption to 1 mW typical thru V , crucial in portable computing,
CC
handheld instrumentation and other low-power applications. The RP power control input also provides
absolute data protection during system powerup/down.

Manufactured on Intel’s 0.8 micron ETOX process, the 28F008SA provides the highest levels of quality,
reliability and cost-effectiveness.
