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.
TARGET APPLICATIONS
Building control and automation
Diagnostic equipment
Multi-node/multi-protocol communication hubs
HMI/GUI applications
Data collectors, infotainment/navigation
Telematics/fleet management
OVERVIEW
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 360 KB, 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 LPC54S0xx MCU devices in this family
provide 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 in the OTP or a software
supplied key.
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 µA/MHz. Its flexible communication interfaces make it ideal for HMI and the
connectivity needs of next-generation IoT applications.
