Offering flashless design and security integration, the LPC540xx MCU family provides up to 180 MHz performance while retaining outstanding power efficiency as low as 100 uA / MHz. Its flexible communication interfaces make it ideal for HMI and connectivity needs of next-generation IoT applications.
The LPC540xx MCU family builds on the industry-leading power efficiency introduced with the LPC54000 series. This new family enables continued growth in the connected smart world through new feature integration and advanced security capabilities.
The LPC540xx MCU family, powered by the Arm Cortex-M4 core, offers a larger SRAM with up to 360KB, a quad SPI Flash interface, Ethernet support, a TFT LCD controller and two CAN FD modules, while striking the right balance between feature integration and power efficiency with the Cortex-M4 achieving an active mode current of 100 µA/MHz.
For added security, the new LPC54S0xx MCU devices in this family provide Physical Unclonable Function (PUF) root key using dedicated SRAM for silicon fingerprint making it possible to generate, store, and reconstruct keys. In addition, the LPC54S0xx devices feature an on-chip hardware AES engine to protect the image content and accelerate processing for data integrity and proof of origin. Data can be encrypted or decrypted by the AES engine using the encrypted key stored in the OTP, SRAM PUF-based or a software supplied key.
ENABLING NEXT-GENERATION CONNECTED DEVICES
The LPC540xx MCU family is architected to be power efficient for applications that require data aggregation from several different inputs. This MCU family provides a variety of wake-up sources including the FlexComm peripherals. Once the MCU becomes active, application use cases are endless with 11 FlexComm interfaces for sensors and HMI, options for cloud connectivity, and a graphics display to interact with the information.
