Ferroelectric memory GX85RS2MC replaces FM25V20A/MB85RS2MT for use in navigation devices

The precise positioning, route planning, and data recording functions of smart navigation devices all rely on high-performance data storage support. For example, in high-precision positioning devices such as in-vehicle navigation systems and drone flight control systems, the storage device must simultaneously meet the following requirements:  

Real-time data writing (recording position/attitude data dozens of times per second)  

Extreme environment tolerance (-40°C to 85°C wide temperature range operation)  

Zero-delay data retention upon power loss (preventing sudden power loss from causing trajectory data loss)

Traditional FLASH and EEPROM are increasingly inadequate, while the GXSC ferroelectric memory GX85RS2MC emerges as an ideal alternative solution with three breakthrough advantages. This ferroelectric memory can be seamlessly pin-to-pin compatible with Cypress FM25V20A and Fujitsu MB85RS2MT.

Seamless replacement and significant advantages of GX85RS2MC:

1. The 2M-capacity ferroelectric memory GX85RS2MC supports 1E11 read/write operations, supports 40MHz high-speed read commands, and offers data retention of 10 years at 85°C (200 years at 25°C). Its operating temperature range is -40°C to 85°C, making it suitable for industrial-grade applications. These performance improvements significantly enhance the user‘s navigation experience.

2. The GX85RS2MC is fully compatible with the FM25V20A and MB85RS2MT in terms of pin definition and packaging format. This allows navigation device manufacturers to replace the existing memory with the GX85RS2MC without requiring major circuit board redesign, simply by swapping out the chip to complete the hardware upgrade. This pin-compatible design significantly reduces the cost and technical complexity of product upgrades while shortening the R&D cycle.

3. 100% Chinese supply chain with stable delivery times. The GXSC ferroelectric memory offers good compatibility and supports SPI and I²C interfaces, making it easy to integrate with other hardware devices in the system. This allows system developers to conveniently embed the ferroelectric memory into the system, reducing the complexity and time costs of system development.

Summary: Through this solution, the GX85RS2MC maintains hardware compatibility while meeting users‘ higher requirements for navigation accuracy, reliability, and convenience, significantly enhancing system reliability and reducing power consumption. It is an excellent choice for replacing the FM25V20A/MB85RS2MT in navigation devices.
