China's population aging process is continuing to accelerate: According to the United Nations 2010 population outlook, the percentage of China's population over 60 years old in 2010 was 12.3%, and it is expected to increase to 24.4% by 2030 and even 33.9% by 2050. . At the same time, as people's living standards improve, life expectancy is getting longer and longer, and more attention will be paid to medical care and health care. Outpatient/home health care will become more and more common. Moreover, the aging of the population may lead to higher rates of heart disease, diabetes, asthma, and the Chinese government plans to achieve universal health insurance, etc., China's medical equipment industry will continue to develop.
At present, China's medical equipment market is scattered, and only a few large medical equipment companies such as Mindray, Jin Kewei, Omron and so on, the market potential is huge, many small companies are also targeting this market, vying to develop innovative medical solutions. Therefore, the development trend of medical equipment includes the addition of "smart" and data storage characteristics, portability, wireless/connected solutions, human body area networks, and the like. Medical semiconductors undoubtedly play a leading role in the innovation of medical devices/solutions, towards higher integration, miniaturization, and energy efficiency, while shifting consumer medical devices to standard components and embedding wireless capabilities.

Implant
Implant applications primarily include defibrillators and cardiac pacemakers, neurostimulators, injectable monitors, and respirable electrons. ON Semiconductor provides ASICs, memory, discrete components, modules and foundry services for such applications.
Using an implantable neurostimulation platform, ON Semiconductor offers a single-chip solution with integrated controller, memory, digital, analog, and high-voltage, using a multi-channel surge suppressor (TSS) to further significantly reduce the number of discrete components (usually IC Reduce the number of dies from 3-4 to 1-2), help reduce board space, simplify equipment manufacturing and logistics, reduce cost and power consumption, reduce system/board reliance, and improve quality Speed ​​up time to market and reduce development risks.

To achieve lower cost and higher energy efficiency, ON Semiconductor also offers serial SRAM memory instead of EEPROM, FRAM and standard SRAM. Parallel SRAM typically requires three control inputs, 15 address inputs, and eight data I/Os for a total of 26 lines, for low-power applications only. The serial SRAM only needs a total of 4 lines, and the footprint is smaller, the pins are smaller, the power consumption is lower, the average backup data can be saved for 10 years, and the system cost is lower, which is very suitable for cardiac monitoring equipment, etc. Small size application.
In particular, to meet specific requirements of the FDA III, ON Semiconductor offers medical-grade standard components for implant or life-critical applications, and provides MIL-STD-750 compliance with MIL-PRF-1950 certification. A high-reliability process that supports JAN/JANHC quality levels and military-standard protocol models such as production line manufacturing approved by the Defense Logistics Agency (DLA).
Hearing aid
Hearing aids are mainly classified into Behind-The-Ear (BTE) and In-The-Ear (ITE) depending on the wearing position. The former includes traditional BTE, micro BTE and Receiver-In-Canal (RIC), the latter including full, 3/4, half-ear cavity ITE, ear canal (ITC), deep ear canal (Completely- In-Canal, CIC) and Invisible-In-Canal (IIC).
Figure 2: Overview of the main types of hearing aids
Micro and "invisible" are a major trend for hearing aids: smaller RICs and new IIC types are more popular, requiring semiconductor manufacturers to move to 65 nm or smaller nodes and miniaturized packaging technology; hearing aids The second trend is to add wireless communication and connectivity: current 2.4 GHz, 900 MHz and Near Field Magnetic Induction (NFMI) technology with Bluetooth relay devices require interoperability and advanced packaging technology; third, hearing aids will evolve To be more "smart" and fully automated: such as volume control and signal processing automatically adapt to the sound environment, making the user more comfortable, which requires increased processing power and algorithm complexity. The development of hearing aids creates design challenges in terms of power consumption, size, and mixed-signal processing, such as requiring less than 1 mA of current consumption at 1 V operating voltage, multi-chip and chip area less than 10 mm2, digital and analog functions, and more.

Custom medical ASIC
Medical device designers generally face the following design challenges:
* Low energy consumption: Battery-powered medical devices require high battery life, while standard discrete components can consume too much current to provide satisfactory product life; *Small size: usually required to be small to provide dispersion and comfort Degree, while using standard discrete components will make the form factor too large; * High voltage: the sensor may require high voltage bias and generate a very low level signal. When using discrete components to handle high voltage and low voltage, the sensor interface circuit is usually too Complex; *Low noise: The signal captured by the dedicated human sensor is very weak, leakage current or other unwanted current will overwhelm the signal generated by the sensor; *Long product life cycle: possibly more than 10 years, and many standard components in medical equipment It has been eliminated before the end of production; * Low BOM cost: The number of system components designed with discrete components is large, and the cost cannot be reduced.
A custom ASIC solution delivers power efficiency, high size integration, high voltage and low voltage circuitry, high signal path isolation and low noise, long product lifecycles, and integrated solutions to reduce system cost. Help designers solve their unique design challenges.
