FT28C010 datasheet(17/30 Pages) FORCE

17 / 30 page

The FT28C010 is accessed like a Static RAM for the read

or write cycle without the need for external components.

The device contains a 128-byte page register to allow writ-

ing of up to 128-bytes simultaneously. During a write cycle,

the address and 1 to 128-bytes of data are internally

latched, freeing the address and data bus for other opera-

tions. Following the initiation of a write cycle, the device will

automatically write the latched data using an inter nal con-

trol timer. The end of a write cycle can be detected by

DATA POLLING of I/O7. Once the end of a write cycle has

been detected a new access for a read or write can begin.

Force's 28C010 has additional features to ensure high

quality and manufacturability. The device utilises internal

error correction for extended endurance and improved data

retention characteristics. An optional software data protec-

tion mechanism is available to guard against inadvertent

writes. The device also includes an extra 128-bytes of

EEPROM for device identification or tracking.
