NXP Semiconductors NV unveils the LPC408x and LPC407x MCUs as cost-effective, low-power solutions for digital signal control, in displays, scanners, industrial networking, alarm systems, medical diagnostics, and motor-control applications.

The MCUs are based on ARM Cortex-M4 processors, and offer advanced signal processing capabilities and a wide range of connectivity options, including USB 2.0, Ethernet and CAN 2.0B. They are drop-in compatible with NXP's popular LPC178x and LPC177x series, as well as multiple LPC2000 MCUs, with 512KB of flash, 96KB of SRAM, 4KB of EEPROM, two analogue comparators, and a wide range of connectivity peripherals, including up to five UARTs, three SPI/SSP, and three I2C interfaces.

Operating at speeds of up to 120MHz, the MCUs feature a multi-layer AHB bus that allows high-bandwidth peripherals such as Ethernet and full-speed USB to run simultaneously, without affecting performance. Other serial peripherals include two CAN controllers, SD/MMC and an I2S interface.

Like the dual-core LPC4300 family, the MCUs feature an optional 32bit floating point unit, as well as a graphical LCD controller offering 1,024 x 768 pixel display resolution. The LPC MCUs also feature NXP's unique SPI flash interface (SPIFI), which allows embedded system designers to add a significant amount of low-cost memory.

Development boards for the MCUs are available from Code Red Technologies and Embedded Artists, with additional boards to be released by IAR later this year.

Samples of the LPC408x and LPC407x MCUs will be available by the end of September 2012 in 80-, 144- or 208-pin LQFP packages and in 180- or 208-pin TFBGA packages.
