M50FW080 is an 8 Mbit (1M x8, Uniform Block) 3V Supply Firmware Hub Flash Memory, and its main features are VCC = 3V to 3.6V for Program, Erase and Read Operations, VPP = 12V for Fast Program and Fast Erase, as well as 5 Signal Communication Interface supporting Read and Write Operations, Hardware Write Protect Pins for Block Protection, Register Based Read and Write Protection.
The M50FW080 is an 8 Mbit (1 M × 8) non‑volatile flash memory that can be read, erased and re‑programmed using a single low voltage (3.0 to 3.6 V) supply. An optional 12 V supply can be applied for fast programming and fast erasing in production lines.
Two bus interfaces are supported: the primary Firmware Hub (FWH) interface, which uses Intel’s proprietary protocol and replaces the ISA bus in PC chipsets, and a secondary Address/Address‑Multiplexed (A/A Mux) interface compatible with standard flash programmers.
| Supply voltage (Vcc) | 3.0 V to 3.6 V |
|---|---|
| Optional fast‑program voltage (Vpp) | 12 V |
| Typical programming time | 10 µs |
The M50FW080 operates from a single low voltage of 3.0 V to 3.6 V.
Yes, a 12 V optional supply (Vpp) can be used to reduce programming and erasing times.
Typical programming time is about 10 µs.
