Digital signal controller family offers advanced signal processing capabilities and a wide range of connectivity options

September 19, 2012 // By Paul Buckley
NXP Semiconductors N.V. has announced the availability of its LPC408x and LPC407x microcontrollers, featuring 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 LPC4000 microcontrollers offer drop-in compatibility with NXP’s popular 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, ideal 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.

The LPC407x/8x devices will be available in LQFP packages with 80, 144 or 208 pins and in TFBGA packages with 180 or 208 pins. Product samples will be available from major distribution partners by the end of the month. Development boards are now available from Code Red Technologies and Embedded Artists, with additional boards to be released by IAR later this year.

Featuring the NXP LPC4078 microcontroller, the Code Red RDB4078 Development Board includes a 320 x 240 IPS touchscreen with wide viewing angle, Ethernet, RS232, USB device and host, microSD, as well as advanced audio functionality including high-quality Wolfson stereo codecs and stereophonic digital microphones on board. All I/O functionality is accessible simultaneously, without the need to reconfigure the board. The RDB4078 includes on-board debug
