LPC2917/2919

ARM968E-S processor in little-endian byte order.



LPC2917/2919

NXP LPC29xx microcontrollers are based on 80-MHz ARM968E-S MCUs with two CAN controllers and up to two LIN controllers

LPC2917 ARM9 microcontroller with 512KB flash, 48KB SRAM, 2 CAN channels, 2 LIN masters
LPC2919 ARM9 microcontroller with 768KB flash, 48KB SRAM, 2 CAN channels, 2 LIN masters

< Key Features >

  • ARM968E-S processor at 80 MHz maximum
  • Multi-layer AHB system bus at 80 MHz with three separate layers
  • On-chip memory:
  • Two Tightly Coupled Memories (TCM), 16 kB Instruction (ITCM), 16 kB Data TCM
    (DTCM)
  • Two separate internal Static RAM (SRAM) instances; 32 kB SRAM and 16 kB
    SRAM
  • Up to 768 kB flash-program memory
  • Two-channel CAN controller supporting Full-CAN and extensive message filtering
  • Two LIN master controllers with full hardware support for LIN communication
  • Two 550 UARTs with 16-byte Tx and Rx FIFO depths
  • Three full-duplex Q-SPIs with four slave-select lines; 16 bits wide; 8 locations deep; Tx
    FIFO and Rx FIFO
  • Four 32-bit timers each containing four capture-and-compare registers linked to I/Os
  • 32-bit watchdog with timer change protection, running on safe clock.
  • Up to 108 general-purpose I/O pins with programmable pull-up, pull-down or bus
    keeper
  • Vectored Interrupt Controller (VIC) with 16 priority levels
  • Two 8-channel 10-bit ADCs provide a total of up to 16 analog inputs, with conversion
    times as low as 2.44 μs per channel. Each channel provides a compare function to
    minimize interrupts
  • Up to 24 level-sensitive external interrupt pins, including CAN and LIN wake- up
    features
  • External Static Memory Controller (SMC) with eight memory banks; up to 32-bit data
    bus; up to 24-bit address bus
  • Processor wake-up from power-down via external interrupt pins; CAN or LIN activity
  • Flexible Reset Generator Unit (RGU) able to control resets of individual modules
  • Flexible Clock-Generation Unit (CGU) able to control clock frequency of individual
    modules
  • On-chip very low-power ring oscillator; fixed frequency of 0.4 MHz; always on to
    provide a Safe_Clock source for system monitoring
  • On-chip crystal oscillator with operating range from 10 MHz to 50 MHz - max. PLL
    input 15 MHz
  • On-chip PLL allows CPU operation up to a maximum CPU rate of 80 MHz
  • Generation of up to 10 base clocks
  • Seven fractional dividers
