MC33FS6502LAE is a battery-backed, 32-bit Flash memory solution designed to provide non-volatile storage for automotive and industrial applications. This non-volatile device utilizes a single 2.6 to 5.5V supply and is designed to be used as an off-line system monitoring, anti-theft and revision control storage device. It has a 5-pin SOT23-2 package and is designed to fit smaller applications. Its 8-pin SSOP package utilizes its extended memory capacity. This device has the following features:

Application Field

MC33FS6502LAE is ideal for battery-backed, non-volatile surveillance and monitoring systems, automotive theft control systems and revision control applications. This device can also be used in applications where real-time data is to be kept secure such as vehicle tracking and race timekeeping applications where track positioning and elapsed time can be stored for post-race analysis. It can be used in major industrial, military and medical applications that require data revision control, off-line surveillance monitoring, battery-backed protection and industrial control.

Working Principle

The MC33FS6502LAE is a flash memory system designed to provide non-volatile storage of up to 32-bits of data in a single, low-power SOT23-2 package. It is designed to be used as a self-contained memory subsystem, allowing the device to store and retrieve data without the need for external memory devices and controllers. The system is designed as a single chip solution and is managed through a single CS pin that controls all read/write operations. This device utilizes a built-in Flash EPROM array for non-volatile storage, allowing it to maintain its memory state over power loss and other environmental conditions.

An internal array of gates controls logic functions such as clock generation and read/write control. When the CS pin is pulled low, the device is activated and allows data to be written, and read, to/from the memory array. At the same time, the device allows a small block of data to be backed up to remain in memory even in the event of a power loss. A separate control line is used to write to the backup block, but the data stored is still affected by a power loss, such as during a battery change.

MC33FS6502LAE is designed to operate from a single 2.6 to 5.5V power supply and features an active read current of 20mA (maximum) or 1µA (during sleep mode) and a write current of 33mA (maximum). The device features continuous data protection and is resistant to various environmental conditions making it ideal for automotive and industrial applications. This device also offers enhanced security features such as write protect register, write disable mask and unique 16-bit signature.

Conclusion

MC33FS6502LAE is a non-volatile flash memory solution designed to offer automotive and industrial users a complete data storage and retrieval solution in a single, low power package. The device is designed to provide continuous data protection and is resistant to various environmental conditions, making it an ideal choice for battery-backed off-line monitoring and anti-theft systems. It also offers enhanced security features such as write protect register, write disable mask and a unique 16-bit signature.
