 Welcome to this presentation on our ACIP technology. ACIP originally stands for application-specific integrated passives. The acronym has now been extended to application-specific integrated products, and we will show you how those products are perfect companionships for our microcontroller units. Let's start with a quick introduction on the product lineup of interest. ST sells an entire range of protection devices and integrated products. Among that product family, we will focus in this presentation on ACIPs. Not to be confused with A6, application-specific integrated circuits. ACIPs include a variety of products mainly focusing on filtering functions. What is an ACIP? The ACIP technology allows for the integration of passive and active devices into a single product. In other words, a lot of the small discrete devices that you can usually find around an ACIP can be integrated into an ACIP. The main benefits one will get are an overall size reduction, a bomb reduction, a design simplification, an optimization of the overall performance of the circuit, and a higher reliability thanks to the monolithic structure of the device. Let's have a look at the typical cross-section of an ACIP. Typically, the ACIP technology allows for the integration of capacitors, metal insulator metal type, resistors, inductors, and system-level ESD protections compliant with the highest level of the IEC 61000-4-2 standard. Depending on the technology and process variant that is used, the maximum value of the components that can be integrated varies as well as the corresponding tolerance. Sub-picofarad capacitors, all the way to 100 plus nanofarad capacitors can be integrated. Resistors from one ohm to hundreds of kilovolms can be used and inductors usually range all the way up to about 114 nano-handry. The process consists in a thin-film deposition of different metal and dielectric layers on a silicon stop straight in which active components can be diffused. Either plastic or CSB type of packages like Flipchip can be considered. What are the benefits of ACIPs? First, these products can be customized, and the time needed to get samples from the moment the custom design is fixed is relatively short, usually in the range of eight weeks. ACIPs allow one to enhance the performance of a circuit compared to the equivalent discrete solution thanks to lower parasitics and better matching of the different components. ACIPs provide designers with a relatively flexible solution, flexibility that can be increased even more through the use of MPW options, multi-product wafers, during the development phase. MPW allows for the design of different flavors of the same product on a single wafer. The total resulting circuit is usually smaller than the equivalent discrete solution. We have seen size reductions of up to 70%. In a world where miniaturization is becoming a common language for all markets, that is a significant benefit. ACIPs can help reduce the cost of a system, and the process to bring a product to full maturity is usually straightforward and well-defined. If a more intelligent function needs to be developed, ST also has a technology so-called smart ACIP. It consists in using the same bricks as a standard ACIP with the possibility to add more active components, such as LDOs, transistors, multiplexers, or logic control, for example. When discrete solutions become too complex, too big, too expensive, or simply not performant enough, the smart ACIP can be the go-to technology. And as we mentioned earlier on, the whole point of using ACIPs is that they're perfect companion chips to our microcontrollers. In this section, we will show typical examples of ACIPs that can be used around the MCU for different applications. Through their programmable core, MCUs allow designers to work on a variety of applications. Some functions can, however, not be handled by the MCU and have to be implemented separately on the PCB. Those functions vary from filtering to signal conditioning or power management. The MCU usually also needs to be protected against system-level electrostatic discharges. On this chart, we're showing a non-exhaustive list of applications for which ACIPs can bring a lot of benefits. Let's go through them one by one. The first typical type of ACIP, as he offers, are integrated common-mode filters with ESD protections. They come in two to six-line devices and are typically needed for high-speed transmission lines, such as USB or HDMI. The goal here is to offer the functionality of a common-mode filter, meaning to suppress the common-mode noise while being transparent to the differential signals and provide full IEC 61000-4-2 system-level ESD protection at the same time. A whole family of ECMF devices, with different mechanical or electrical characteristics, were developed to address all potential applications needing such kind of function. The example given here is that of a MEP type of connection. The ACIP technology also allows ST to design tiny integrated baseband filters that can be housed in packages as small as a three-lead 0201. In the case of this CRC low-pass filter plus ESD, the benefit in terms of size reduction is pretty significant compared to the equivalent discrete solution. Another application that can be handled by an ACIP consists in audio filtering. The EMIFO2-SPK02F2 consists in a tiny integrated EMI filter for audio applications, rejecting the typical GSM, Bluetooth, and Wi-Fi frequencies to avoid any unwanted noise in the sound. Once again, in addition to that, the device also provides full system-level ESD protection. Similar to the previous application, other multi-line integrated EMI filters plus ESD protections were developed for a variety of applications, such as memory cards and SIM card signal conditioning. The goal is always the same, meaning trying to gain space, produce the cost of the function, and simplify the design. Using the more complex smart ACIP technology, the HDMI2C series of products was developed to provide level-shifting signal conditioning and boosting under control links of the HDMI port while protecting it against system-level ESD protection. This device would be essential to anyone willing to easily comply with the latest HDMI specification. It is a plug-and-play device that can be adapted to any kind of HDMI transceiver and replaces a whole lot of discrete devices normally necessary to perform that function. Another product family that is currently being deployed by SD, using our smart ACIP technology is the TCPP series. TCPP stands for Type-C port protection and refers to the latest USB type of port. The latest reversible USB Type-C port features a well-known weakness in the sense that during plugging or unplugging of the connector, a short circuit can happen between the configuration channel lines and the VBUS line, potentially destroying the USB transceiver through an overvoltage event. The TCPP products were developed as companionships to the USB PD-enabled STM32MCUs from SD, the G0, G4, L5, and U5 series. They provide a whole lot of complex functionalities such as overvoltage protection against short to VBUS on the CC lines, overvoltage protection on the VBUS itself, and over-temperature protection as well as an integrated driver for the VBUS load switch. Everything comes once again, accompanied with standard system-level ESD protection to satisfy any designer willing to take advantage of all the functionalities that our 32-bit MCUs provide while designing a robust USB power delivery function. All of that comes in a small 3x3 12-pin QFN package. The last subfamily of ACIPs we can talk about are the IPD devices. The acronym IPD stands for Integrated Passive Devices. Those products are more dedicated to all types of RF filtering functions. If you wish to know more about those products, I strongly recommend you watch our video dedicated to RF IPDs for the 5G environment that can also be seen on ST's virtual IoT world booth. Now, what is the conclusion of all this? The ACIP technology can cover a wide variety of applications, and those products are the ideal companion ships to any kind of MCU. ACIPs provide our customers with design simplification as well as space and most of the time cost savings. For further information, please visit our website at www.st.com.
