GXSC Ferroelectric Memory GX85RS2MC can be used in vending machines and is compatible with MB85RS2MT.

In the process control of vending machine, the subsystem is mainly composed of vending price system, detection system, accumulation and self-testing function system, and accumulation and saleable index. The same kind of goods sold by the vending machine can be divided into a number of varieties, and their pre-sale set prices must be stored in the control system in advance.

The price setting system of the vending machine is composed of keys and memory, the type and price of the goods to be priced are selected by the keys and the price is written into the memory, which needs to have a power-down protection function to avoid accidental power failure and data loss and need to be rewritten.

In summary, non-volatile, high-speed writing speed, low-power ferroelectric memory can meet the storage needs of the vending machine, this paper recommends the use of GXSC ferroelectric memory GX85RS2MC used in the program, the model has been widely used in the field of smart IC cards, power meters, industrial fields, medical equipment, automotive field, involving more than 200 kinds of applications.

The current ferroelectric memory has three main advantages: high read/write endurance, high-speed writing and low power consumption, which is incomparable to the vast majority of the same type of memory. For example, ferroelectric memories have a write life of up to 1 million times, compared to 100,000 times for EEPROMs, giving them a huge advantage in vending machines and other battery-powered applications.

The GX85RS2MC has a capacity of 2M bit and performance compatible with the MB85RS2MT, using a memory cell that can be used for 1E6 read/write operations*1 and data retention: 10 years @ 85°C (200 years @ 25°C); it operates in an ambient temperature range of -40°C to 85°C, which is in line with application scenarios for industrial-grade products.
