NXP LPC18Sxx

LPC18Sxx MCUs with integrated security and up to 180 MHz

NXP’s high-performance LPC18Sxx microcontrollers offer CPU speeds up to 180 MHz with added security features to enable designers to protect application IP and prevent unauthorized access to data messages.

With hardware accelerated AES encryption and decryption, two 12-bit non volatile OTP memories for encrypted, hardware randomized key storage, and a true random number generator for unique key creation, the LPC18Sxx family enables applications to implement secure boot, secure messaging, and more. Peripherals for high speed Internet connectivity include a 10/100 Ethernet controller with hardware enabled TCP/IP checksum calculation and SDIO for interfacing to Wi-Fi modules. Other peripherals include Hi-Speed USB with integrated PHY or ULPI, and CAN 2.0. An optimized graphic LCD display controller supports vivid color and monochrome LCD panels with resolutions up to 1024 x 768 pixels. The expandable memory architecture gives developers powerful options for scaling memory to the ideal requirements. In addition, Flash less options with SPIFI lower cost and maximize internal RAM.

LPC18Sxx microcontrollers are supported by a wide range of software solutions available from ecosystem partners that include secure firmware updates, secure IoT connectivity, and secure networking stacks (SSL, TLS).
