16 Mbit SPI Serial Flash Memory Chip IC Microchip SST25VF016B with
Flexible Erase Capability
GENERAL DESCRIPTIONS
The 25 series Serial Flash family features a four-wire,
SPI-compatible interface that allows for a low pin-count package
which occupies less board space and ultimately lowers total system
costs. The SST25VF016B devices are enhanced with improved operating
frequency and even lower power consumption than the original
SST25VFxxxA devices.
SST25VF016B SPI serial flash memories are manufactured with
proprietary, high-performance CMOS SuperFlash technology. The
split-gate cell design and thick-oxide tunneling injector attain
better reliability and manufacturability compared with alternate
approaches. SST25VF016B devices significantly improve performance
and reliability, while lowering power consumption.
The devices write (Program or Erase) with a single power supply of
2.7-3.6V for SST25VF016B. The total energy consumed is a function
of the applied voltage, current, and time of application. Since for
any given voltage range, the SuperFlash technology uses less
current to program and has a shorter erase time, the total energy
consumed during any Erase or Program operation is less than
alternative flash memory technologies.
