NXP expands LPC4000 digital signal controller family
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

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.
