Maxim Integrated Products, INC announced the launch of MAX32666 microcontroller (MCU) supporting wireless connection to help designers reduce the cost of BOM (IoT) product BOM, the power supply of buttons, and greatly saving space and extending battery life.This ultra-low-power dual-core ARM® Cortex®-M4 MCU has floating-point computing units (FPU) and low-power Bluetooth 5.2 (BLE 5.2). Safety functions, communication, power management and processing functions, thereby effectively extend the battery life of the equipment.

With the development of IoT applications towards high -end, more MCUs are usually integrated into the system.These systems usually include special processors responsible for supporting the processing application, a processor as a sensor data concentrator, and a BLE microcontroller responsible for wireless connection. EssenceAs the complexity of IoT applications is getting higher and higher, the product size is getting smaller and smaller and the battery life is getting longer and longer. Traditional multi -chip solutions are difficult to meet subsequent design needs.

MAX32666 MCU is the latest member of the Maxim Integrated's rich -featured Darwin family MCU, which provides high -performance design.Compared with the traditional architecture, the appearance size and occupying area of ​​the MCU have been greatly reduced, allowing IoT product designers to integrate the three chips in the current device and greatly reduce the cost of BOM.This dual-core Cortex-M4F MCU supports the efficient calculation of complex functions. The operating frequency is as high as 96MHz, which is increased by 50%compared to the closest competitive scheme data processing speed.In order to replace a separate PMIC solution, MAX32666 integrates a single inductance multi -output (SIMO) voltage regulator to effectively extend the working hours of small -sized battery power supply products.MCU has BLE 5.2, supports up to 2Mbps data throughput and long-distance transmission (125kbps and 500kbps). The transmitter's output power is as high as+4.5DBM, and it can be programmed to a minimum of -95DBM.The device also uses the trust protection unit (TPU) and the powerful mathematical accelerator to support the ellipse curve digital signature algorithm (ECDSA), thereby protecting the terminal application from the threat of network security.IC's hardware accelerator provides AES-128, 192 and 256 encryption, TRNG seed generator and SHA-2 accelerator to enhance system security.The device also protects the IP firmware through security guidance loading programs.MAX32666's powerful plate storage capacity is very attractive, including up to 1MB flash memory and 560kb SRAM, which can meet the needs of most high -reliability applications (ECC) needs, as well as a variety of high -speed peripheral needs.Device can manage more data through efficient operations and support more powerful applications without exhausting code space -all this has the best power management technology in the industry.

Main advantage

· Reliability: By integrated ECC in Flash, SRAM, and cache, an additional layer of protection is added to prevent the error bits from flipping.

· Low cost: Integrate two microcontrollers in a single -chip IC, and use a proprietary stack nuclear Bluetooth wireless communication, power management, and safe large -capacity memory.By using the dual-core 96MHz Cortex-M4 FPU microcontroller, the boarding 1MB flash memory and 560kb SRAM, the BOM cost is greatly reduced.

· Save the area of ​​circuit board: integrate multiple functions to a single -piece IC encapsulated by small size, 3.8mm x 4.2mm, WLP packaging.

· Low power consumption: lower effective working current, greatly extend the battery life of the butt battery power supply equipment; provide dynamic voltage adjustment to maximize the operating power consumption of the processor core; 3.3V; A variety of cut -off modes effectively extend the working life of the battery, and consume only 1.2UA @ 3.3V in the lowest power consumption mode.

· "From 2015 to 2030, the installation base of IoT devices is expected to increase at a compound annual growth rate of 12%per year, and the number will exceed 80 billion." Julian Watson, chief IoT analyst of OMDIA, said: "Maintain high growth in high growth The key factor of rate is to continue to increase new functions to these devices and improve efficiency, so that end users can recognize their value and convenience. Obviously, Maxim Integrated is promoting the popularity of IoT with its new DARWIN microcontroller. "

· "Any IoT application can continuously increase the function of the microcontroller expansion system, but frequently changing the battery will affect the experience and convenience of the end user." Kris Ardis, executive director of the Maxim Integrated microprocessor and the safety product division, said: " Our new processor family can help designers reduce battery replacement, greatly improve computing performance, and apply the energy -saving advantages of wearable technology to a wider range of IoT products.
