NXP Semiconductors has released two new digital signal controllers, the LPC408x and LPC407x.  The new MCUs  feature advanced signal processing capabilities and a wide range of connectivity options, including USB 2.0, Ethernet, and CAN 2.0B. Based on an ARM Cortex-M4 processor, the new MCUs offer drop-in compatibility with NXP’s LPC178x and LPC177x series, as well as multiple LPC2000 microcontrollers. The LPC408x and LPC407x are a cost-effective, low-power solution for digital signal control, sitable for displays, scanners, industrial networking, alarm systems, medical diagnostics, and motor-control applications.

Operating at speeds of up to 120 MHz, the LPC408x and LPC407x provide up to 512 KB of flash, 96 KB of SRAM, 4 KB of EEPROM, two analog comparators, and a wide range of connectivity peripherals, including up to five UARTs, three SPI/SSP, and three I2C interfaces. The LPC408x and LPC407x series 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 LPC408x and LPC407x microcontrollers feature an optional 32-bit floating point unit, as well as a graphical LCD controller offering 1024 x 768 pixel display resolution. The new LPC microcontrollers also feature NXP’s unique SPI flash interface (SPIFI), which allows embedded system designers to add a significant amount of low-cost memory.
