NXP Semiconductors LPC4078 & LPC4088 32-Bit Microcontrollers

NXP Semiconductors LPC4078 and LPC4088 32-Bit Microcontrollers are Arm® Cortex®-M4 based digital signal controllers for embedded applications requiring a high level of integration and low power dissipation. The Arm Cortex-M4 is a next generation core that offers system enhancements such as low power consumption, enhanced debug features, and a high level of support block integration. The Arm Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals, and includes an internal prefetch unit that supports speculative branching. The Arm Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A hardware floating-point processor is integrated in the core for several versions of the part.

The LPC4078 and LPC4088 MCUs add a specialized flash memory accelerator to accomplish optimal performance when executing code from flash. The LPC4078 and LPC4088 devices are targeted to operate at up to 120MHz CPU frequency.

The peripheral complement of the LPC4078 and LPC4088 includes up to 512 kB of flash program memory, up to 96kB of SRAM data memory, up to 4032bytes of EEPROM data memory, External Memory controller (EMC), LCD, Ethernet, USB Device/Host/OTG, an SPI Flash Interface (SPIFI), a General Purpose DMA controller, five UARTs, three SSP controllers, three I²C-bus interfaces, a Quadrature Encoder Interface, four general purpose timers, two general purpose PWMs with six outputs each and one motor control PWM, an ultra-low power RTC with separate battery supply and event recorder, a windowed watchdog timer, a CRC calculation engine, and up to 165 general purpose I/O pins.

The analog peripherals include one eight-channel 12-bit ADC, two analog comparators, and a DAC.

The NXP Semiconductors LPC4078 and LPC4088 MCUs are available is LQFP208, TFBGA208, TFBGA180, LQFP144, TFBGA80, and LQFP80 packages. The devices are intended to allow pin function compatibility with the LPC24xx/23xx as well as the LPC178x/7x families.
