Description

technical field [0001] The invention relates to a SOC (System On Chip, system on chip) chip of a fuel dispenser control system, which belongs to the fuel dispenser control technology. Background technique [0002] With the advent of the automobile era, the demand for fuel dispensers in the market is increasing, and the performance requirements for fuel dispensers are getting higher and higher. However, the control system of the fuel dispenser currently on the market is generally composed of traditional discrete devices. There are many discrete devices, and the anti-interference performance is poor. The system is susceptible to electromagnetic interference and cannot work normally. Unauthorized modification of the control circuit of the fuel dispenser affects the accurate reading of the fuel volume by the tax control chip, thereby evading taxes and bringing great losses to the state's fiscal revenue. Moreover, the traditional fuel dispenser control system concentrates too ma...

Problems solved by technology

However, due to the high cost of CPLD or FPGA, high power consumption and low utilization of internal resources, the fuel dispenser control system based on CPLD or FPGA is only suitable for the design of small batch fuel dispenser control systems, while the fuel dispenser However, the demand for fuel dispensers is increasing day by day. There is an urgent need for a low-cost, low-power, high-performance fuel dispenser control system that can be mass-produced. Unfortunately, the current fuel dispenser control system cannot meet this demand in the market.
