Semiconductor industry is always evolving at an unprecedented speed. You may feel this trend when changing your smart phone from an older generation to the latest offering from Apple or Samsung, and found that the screen and performance of the device is better than you ever could imagine, just like the time when you change your personla computer several years ago.

 

However, not only the power of a high-end processor is enhancing continuously, the benefit of technology upgrade also lies in MCUs. Intruduced in 2019, NXP's LPC5500 general purpose microcontroller series has brought more computing power into our daily life while maintain low power comsumption. Now, within a year's time, the third family in LPC5500 series——the LPC551x/S1x microcontroller family is in mass production.

 

LPC5500

You may already heard of the LPC5500 MCU series from NXP. Leveraging the Arm® Cortex®-M33 technology, LPC5500 combines significant product architecture enhancements and greater integration over previous generationsof NXP's microcontrollers, offering dramatic power consumption improvements and enhanced security features including SRAM PUF based root of trust and provisioning, real-time execution from encrypted images , and asset protection with Arm TrustZone®-M Technology.

 

LPC551x/S1x

The LPC551x/S1x MCU family expands LPC5500 into a new price point, offering significant advantages for developers, including pin-, software- and peripheral-compatibility for ease of use and to help accelerate time to market, while still leveraging the cost-effective 40-nm NVM process technology.

The LPC551x/S1x is the entry-level family within the LPC5500 MCU series, providing new levels of cost and performance efficiency in addition to security and system integration for industrial, IoT and general embedded applications.

 

Key Strength and differenciators

  • Ultra-efficient 40-nm flash technology
    • Over 600 CoreMarks and as low as 32uA/MHz
  • System Integration for Industrial and IoT Markets
    • High-Precision ADCs
    • CAN-FD for industrial control
    • HS USB with On-Chip PH
  • Enhanced safety and security with Arm TrustZone-M technology
  • Comprehensive enablement with MCUXpresso Ecosystem

 

Applications

LPC551x/S1x is suitable for a wide range of applications such as industrial and building automation, consumer products and smart home applications.

Leveraging the integration of a high-speed/high resolution ADC module, the CAN-FD interface, the LPC551x/S1x is suitable for remote IO, sensor nodes, elevator control panel, smart lighting and other industrial and building automation applications.

Due to its rich interface offering such as CAN-FD, HS USB, up to 8 FlexComm interfaces along with its great power efficiency and low-price, this microcontroller is ideal to be deployed in consumer products such as gaming peripherals, tracking systems and power tools.

Its advanced security features make the LPC551x/S1x MCU family the right fit in security systems and in smart home related applications

 

Enablement

Like other NXP MCUs, LPC551x/S1x is fully supported by NXP's MCUXpresso ecosystem, which includes a free downloadable IDE, dedicated SDK package where you could find lots of example codes, and pin configuration tool.

NXP also designed LPCXpresso55S16 development board as the ideal platform for evaluation and development. The board features an on-board LPC-Link2 debug probe based on the LPC4322 MCU for a performance debug experience over high speed USB, with easy firmware update options to support CMSIS-DSP or a special version of J-link LITE from SEGGER.
