With the rapid growth of the automotive electronics industry, car manufacturers are increasingly relying on electronic components. However, the challenge between high-capacity demand and the inefficiency of traditional programming tools has become more apparent. Why is this happening? Today, we’ll explore this issue through the lens of the car’s “smart key.â€
**First, the Problem**
Many smart key manufacturers begin production using the 2-Link emulator provided by chip suppliers. This tool offers a third-party interface for semi-automatic mass programming. While 2-Link is effective for development purposes, it lacks the stability required for large-scale manufacturing. Users often report that when using 2-Link for production, there's a risk of failed programming. In the strict environment of automotive electronics, where near 100% yield is expected, such instability is simply unacceptable.
**Second, the Cause**
One reason for the unstable programming lies in the weak driving capability of the pin. Online programming isn’t just about the programmer itself; it also depends heavily on the wiring. As the length of the wiring increases, the programming signal gradually weakens. The pin’s driving ability determines how much the signal degrades.
Some programmers on the market use the internal control chip’s IO port or the FPGA pin as the signal input/output, which results in poor driving power. When the wiring is longer than 30 cm, signal distortion occurs, leading to unreliable programming. For car key manufacturers aiming to boost efficiency, they often use jigs with extended wiring, which can cause instability in some programming tools.
**Third, the Solution**
To address these production challenges, we developed the P800isp, a mass-produced online programmer tailored for different customers, based on ten years of experience in simulator and programmer development. With multi-channel signal amplification, the P800isp significantly improves the driving capability of the programmer, effectively solving the issue of unstable programming caused by long wiring.
As shown in the figure below, when the programming line is 25 cm long, the P800isp produces a cleaner waveform compared to other programmers.
In addition to wire length, the material and thickness of the wire also affect programming performance. It’s recommended that users choose wires with high conductivity and thicker diameters. If the wiring is over 50 cm due to specific environmental conditions, reducing the communication frequency can improve stability. The P800isp allows users to adjust the frequency, adapting to various production environments.
In conclusion, the original tool is an emulator designed for simulation and debugging, but it struggles to meet the complex demands of mass production. The P800isp delivers a stronger and cleaner signal, making it a versatile solution. It supports popular chips like PCF79XX and NCF29XX used in keyless entry systems, offering a one-time purchase with lifetime usage.
Pushbutton Switches
There are many types of Push-Button Switches, which can be divided into ordinary button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, with indicator light type, illuminated symbol type and key type etc.The push button switch is a main electric appliance with a simple structure and a wide application. In the electrical automatic control circuit, it is used to manually send out control signals to control contactors, relays, electromagnetic starters and so on.
