Description
This article provides information about the electronic component model LW046A. It belongs to the product category of IC chips and is a 4-Mbit non-volatile memory that can be read, erased, and reprogrammed with a single low voltage supply.
Specifications and features
- Compatible with LPC interface or FWH interface (Intel Spec rev1.1) used in PC BIOS applications
- 5 signal communication interfaces supporting read and write operations
- 5 additional general-purpose inputs for platform design flexibility
- Synchronized with 33MHz PCI clock
- 8 blocks of 64Kbytes each - 5 blocks of 64KBytes each + 3 blocks subdivided into 16 uniform sectors of 4KBytes each
- Two interfaces - auto-detection of firmware hub (FWH) or low pin count (LPC) memory cycles for embedded operation with PC chipsets and Address/Address Multiplexed (A/A Mux) interface for programming equipment compatibility.
- Programming time: 10 µs typical
- Manufacturer Code: 20h, Device Code (M50FLW040A): 08h, Device Code (M50FLW040B): 28h
- ECOPACK® (RoHS compliant)
Application Scenarios
The LW046A electronic component model can be used in computer BIOS applications for reading, erasing, and reprogramming memory. It is also suitable for embedded operations with PC chipsets and programming equipment compatibility.
Comparison
Advantages- The LW046A is compatible with both LPC and FWH interfaces used in PC BIOS applications and has five signal communication interfaces supporting read and write operations.
- The memory is divided into 8 uniform blocks and 16 uniform sectors, making it possible to preserve valid data while old data is erased.
- The device has enhanced security features such as hardware write protect pins for block protection and register-based read and write protection.
- The Programming time is fast at 10 µs typical
- ECOPACK® environmentally friendly packaging (RoHS compliant)
Disadvantages- The device requires a 12V power supply for fast programming and erasing in production lines (optional).
- The application of the device is limited to computer BIOS applications and embedded operations with PC chipsets.
- The component model might not be optimal for other applications.
