Description

The M50FW016 is a 16 Mbit (2Mb x8) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single low voltage (3.0 to 3.6V) supply. For fast programming and fast erasing, an optional 12V power supply can be used to reduce the programming and the erasing times.

The memory M50FW016 is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. Blocks can be protected individually to prevent accidental Program or Erase commands from modifying the memory. Program and Erase commands are written to the Command Interface of the memory. An on-chip Program/Erase Controller simplifies the process of programming or erasing the memory by taking care of all of the special operations that are required to update the memory contents. The end of a program or erase operation can be detected and any error conditions identified. The command set required to control the memory is consistent with JEDEC standards.

Two different bus interfaces M50FW016 are supported by the memory. The primary interface, the Firmware Hub (or FWH) Interface, uses Intel's proprietary FWH protocol. This has been designed to remove the need for the ISA bus in current PC Chipsets; the M50FW016 acts as the PC BIOS on the Low Pin Count bus for these PC Chipsets.

The secondary interface M50FW016, the Address/Address Multiplexed (or A/A Mux) Interface, is designed to be compatible with current Flash Programmers for production line programming prior to fitting to a PC Motherboard.

The memory M50FW016  is offered in TSOP40 (10 x 20mm) package and it is supplied with all the bits erased (set to '1').
