Key features of LPC84x MCU family (LPC844 / LPC845):

  • MCU Core – ARM Cortex-M0+ core @ 30 MHz with advanced power optimization
  • RAM – 16 kB RAM (Logic for Bit banding across all of SRAM)
  • Storage – 64 kB Flash, small 64-byte page size suitable for EEPROM emulation
  • Peripherals
    • Timers – 32-bit CTimer, WWDT, 4-channel multi-rate, SCTimer/PWM
    • Serial Interfaces – Up to 4x I2C, 2x SPI, up to 5x UART
    • Analog Interfaces – 12 ch, 12-bit ADC up to 1.2 Msps; 2x 10-bit DAC; comparator with external Vreg; 9-channel capacitive touch interface working in sleep and deep sleep modes
    • Up to 54 GPIOs
    • 25-ch DMA offloads core
  • Power Control
    • Five power modes
    • Power profile APIs for simple runtime power optimization
    • Fast Access Initialization Memory (FAIM) for low power boot @ 1.5 MHz
  • Clock Generation Unit with Free Running Oscillator
  • Packages – LQFP64, LQFP48, HVQFN48 and HVQFN33

The LPC84x MCUs target applications typically making use of 8- or 16-bit MCUs such as sensor gateways, gaming controllers, motor control, fire & security, climate control, lighting, etc.. The company has already provided code samples that can be used in MCUXpresso, Keil, and IAR IDEs, as well as a datasheet, and a user guide for the microcontrollers on the product page.

NXP also unveiled LPCXPresso845-MAX development board (OM13097) to help quickly evaluating the new MCUs. The board comes with the following key features:

  • LPC845 MCU
  • On-board CMSIS-DAP (debug probe) with VCOM port, based on LPC11U35 MCU
  • Debug connector to allow debug of target MCU using an external probe
  • Red, green and blue user LEDs;  Target ISP and user/wake buttons; Target reset button
  • LPCXpresso expansion connector
  • DAC output via speaker driver and speaker
  • Arduino connectors compatible with the “Arduino UNO” platform
  • Pmod compatible expansion header
  • Prototyping area

NXP did not disclose pricing for LPC84x MCUs, but it should be priced competitively against 8-bit micro-controllers. LPCXpresso845-MAX development board (OM13097) can be purchased for $19 directly on NXP website.
