SC95F8523/8522/8521 (hereinafter referred to as the SC95F852X) is a series of enhanced 1T 8051 core industry- standard Flash Microcontroller unit (MCU) with integrated TouchKey function, the instruction set is compatible with the standard 80C51 series.

The SC95F852X has a Super-high-speed 1T 8051 CPU core with an operating frequency of up to 32MHz. The SC95F852X integrates a hardware multiplier and divider and dual DPTR data pointers to accelerate data operations and movement speed. The hardware multiplier and divider does not occupy CPU cycles, and the operation is implemented by hardware, and the speed is dozens of times faster than the multiplication and division speed realized by software; dual DPTR data pointers can be used to accelerate data storage and movement.

• The L298 is an integrated monolithic circuit in a 15- lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.
