Block diagram: LPC2290FBD144


Enhancements introduced with LPC2290/01 device
  • CPU clock up to 72 MHz and 64 kB of on-chip static RAM.
  • Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original LPC2290. A port pin can be read at any time regardless of its function.
  • Dedicated result registers for ADC reduce interrupt overhead.
  • UART0/1 include fractional baud rate generator, auto-bauding capabilities and handshake flow-control fully implemented in hardware.
  • SSP serial controller supporting SPI, 4-wire SSI, and Microwire buses.

Key features common for LPC2290 and LPC2290/01

  • 16/32-bit Arm7TDMI-S microcontroller in a LQFP144 package.
  • 16/64 kB on-chip static RAM.
  • Serial bootloader using UART0 provides in-system download and programming capabilities.
  • EmbeddedICE-RT and Embedded Trace interfaces offer real-time debugging with the on-chip RealMonitor software as well as high-speed real-time tracing of instruction execution.
  • Two interconnected CAN interfaces with advanced acceptance filters. Additional serial interfaces include two UARTs (16C550), Fast I²C-bus (400 kbit/s) and two SPIs.
  • Eight channel 10-bit ADC with conversion time as low as 2.44 us.
  • Two 32-bit timers (with four capture and four compare channels), PWM unit (six outputs), Real-Time Clock (RTC) and watchdog.
  • Vectored Interrupt Controller (VIC) with configurable priorities and vector addresses.
  • Configurable external memory interface with up to four banks, each up to 16 MB and 8/16/32-bit data width.
  • Up to 76 general purpose I/O pins (5 V tolerant). Up to nine edge/level sensitive external interrupt pins available.
  • 60/72 MHz maximum CPU clock available from programmable on-chip PLL with settling time of 100 us.
  • On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz.
  • Power saving modes include Idle and Power-down.
  • Processor wake-up from Power-down mode via external interrupt.
  • Individual enable/disable of peripheral functions for power optimization.
  • Dual power supply:
    • CPU operating voltage range of 1.65 V to 1.95 V (1.8 V +- 0.15 V).
    • I/O power supply range of 3.0 V to 3.6 V (3.3 V +- 10 pct) with 5 V tolerant I/O pads.
