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

 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 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
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.
