Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MSP430F5172IRSBR is an ultra-low-power, 16-bit mixed-signal microcontroller (MCU) in the MSP430F5xx family, available in a 40-pin WQFN package (5 x 5 mm) for applications such as the Internet of Things (IoT), industrial automation, sensor networks, medical devices and consumer electronics.

MSP430F5172IRSBR Product Features

Low-power modes: Multiple low-power modes are available, including LPM3 (standby mode, WDT mode, 1.1 µA at 3 V), LPM4 (shutdown mode, RAM hold, 0.9 µA at 3 V), and LPM4.5 (shutdown mode, 0.25 µA at 3 V). Wake-up time from standby mode is less than 5 µs.

High-performance processor: 16-bit RISC architecture with 40ns instruction cycle time and support for clock frequencies up to 25MHz.

Storage options: 32KB of internal Flash and 2KB of SRAM to meet the storage needs of most embedded applications.

Rich peripheral interfaces: including two 16-bit high-resolution timers (Timer TD0 and Timer TD1, both support high-resolution mode), a 16-bit timer TA0, 3-channel DMA, general-purpose serial communication interfaces (USCI_A0 supports enhanced UART, IrDA encoder and decoder, synchronous SPI; USCI_B0 supports I2C and synchronous SPI), and a 10-bit 200-bit serial interface. SPI; USCI_B0 supports I2C and synchronous SPI) and a 10-bit 200ksps analogue-to-digital converter (ADC) with a built-in reference voltage source and sample-and-hold functionality, supporting up to 8 external channels and 2 internal channels.

Flexible power management system: Integrated programmable voltage regulators support a wide supply voltage range of 1.8V to 3.6V with supply voltage supervision, monitoring and undervoltage reset.

Unified Clock System: Phase-locked loop (FLL) with frequency stabilisation control loop, low-power low-frequency internal clock source (VLO), low-frequency calibrated internal reference source (REFO), 32kHz crystal (XT1), and high-frequency crystals (XT1) supporting up to 25MHz.

Hardware Multiplier: Hardware multiplier supporting 32-bit operation to accelerate mathematical operations.

High-tolerance I/O: Provides up to 12 digital push-pull I/Os with 5V tolerance and maximum drive current of up to 20mA per pin.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
