Microchip Passive Keyless Entry (PKE) Reference Design

The manual describes a passive keyless entry (PKE) system upgrade for existing remote keyless entry (RKE) applications. The key design includes a PIC16F639 microcontroller with an integrated three-axis analog front-end (AFE). A PIC18F2680 microcontroller is used to implement the low-frequency transmitter.

Mornsun Electric Vehicle Power Supply Design Reference

The difference between electric vehicles and traditional fuel vehicles lies in the power part, which is also the core part of electric vehicles. Pure electric vehicle systems usually include three systems, namely the electric drive subsystem, the main energy subsystem and the auxiliary control subsystem. Among them, the electric drive subsystem consists of an electronic controller, a power converter, an electric motor, a mechanical transmission device and drive wheels; the main energy subsystem consists of a main power supply, an energy management system and a charging system; the auxiliary control subsystem has functions such as power steering, temperature control and auxiliary power supply.

High-quality Bluetooth speaker design reference

Although the common Bluetooth speakers on the market are relatively cheap, their sound quality is far from satisfactory and cannot meet people's pursuit of high-quality sound. The fundamental reason is that the Bluetooth speaker box is too small and the speaker is too small, resulting in a serious lack of bass; the resonance of the plastic box causes muddy sound; the speaker is too close and the near-field sound is too narrow, etc. This design reference integrates the MaxxAudio sound enhancement chip NPCA110P, which greatly improves the problems of muddy sound, insufficient bass, and narrow near-field sound.
