AM29F016D-90SC

The AM29F016D-90SC is one member of the AM29F016D series.The following document specifies Spansion memory products that are now offered by both Advanced Micro Devices and Fujitsu.Although the document is marked with the name of the company that originally developed the specification, these products will be offered to customers of both AMD and Fujitsu.The system may also write the autoselect command sequence when the device is in the Erase Suspend mode. The device allows reading autoselect codes even at addresses within erasing sectors, since the codes are not stored in the memory array. When the device exits the autoselect mode, the device reverts to the Erase Suspend mode, and is ready for another valid operation. See "Autoselect Command Sequence"for more information.

Features of the AM29F016D-90SC are:(1)32 uniform sectors of 64 Kbytes each; (2)any combination of sectors can be erased; (3)supports full chip erase; (4)embedded erase algorithm automatically preprograms and erases the entire chip or any combination of designated sectors; (5)embedded Program algorithm automatically writes and verifies bytes at specified addresses; (6)25 mA typical active read current; (7)30 mA typical program/erase current.

The absolute maximum ratings of the AM29F016D-90SC can be summarized as:(1)ambient temperature with power applied:-55 to 125;(2)storage temperature plastic packages:-65 to 125;(3)voltages with respect to ground Vcc:-2.0 to 7.0V;(4)output short circuit current:200mA.The internal state machine is set for reading array data upon device power-up, or after a hardware reset.This ensures that no spurious alteration of the memory content occurs during the power transition. No command is necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses on the device address inputs produce valid data on the device data outputs. The device remains enabled for read access until the command register contents are altered.An erase operation can erase one sector, multiple sectors, or the entire device. The Sector Address Tables indicate the address space that each sector occupies. A "sector address" consists of the address bits required to uniquely select a sector. See the "Command Definitions" section for details on erasing a sector or the entire chip, or suspending/resuming the erase operation.
