Features

  • Arm7TDMI-S processor, running at up to 72 MHz.
  • Up to 128 kB on-chip flash program memory with In-System Programming (ISP) and In-Application Programming (IAP) capabilities. Flash program memory is on the Arm local bus for high performance CPU access.
  • 8 kB (LPC2361) or 32 kB (LPC2362) of SRAM on the Arm local bus for high performance CPU access.
  • 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM.
  • 8 kB SRAM for general purpose DMA use also accessible by the USB.
  • Dual Advanced High-performance Bus (AHB) system that provides for simultaneous Ethernet DMA (LPC2362 only), USB DMA, and program execution from on-chip flash with no contention between those functions. A bus bridge allows the Ethernet DMA to access the other AHB subsystem.
  • Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts.
  • General Purpose DMA controller (GPDMA) on AHB that can be used with the SSP serial interfaces, the I²S port, as well as for memory-to-memory transfers.
  • Serial interfaces:
    • Ethernet MAC with associated DMA controller (LPC2362 only). These functions reside on an independent AHB.
    • USB 2.0 device/host/OTG with on-chip PHY and associated DMA controller.
    • Four UARTs with fractional baud rate generation, one with modem control I/O, one with IrDA support, all with FIFO.
    • CAN controller with two channels.
    • SPI controller.
    • Two SSP controllers, with FIFO and multi-protocol capabilities. One is an alternate for the SPI port, sharing its interrupt and pins. These can be used with the GPDMA controller.
    • Three I²C-bus interfaces (one with open-drain and two with standard port pins).
    • I²S (Inter-IC Sound) interface for digital audio input or output. It can be used with the GPDMA.
  • Other peripherals:
    • 70 general purpose I/O pins with configurable pull-up/down resistors.
    • 10-bit ADC with input multiplexing among 6 pins.
    • 10-bit DAC.
    • Four general purpose timers/counters with a total of 8 capture inputs and 10 compare outputs. Each timer block has an external count input.
    • One PWM/timer block with support for three-phase motor control. The PWM has two external count inputs.
    • Real-Time Clock (RTC) with separate power pin, clock source can be the RTC oscillator or the APB clock.
    • 2 kB SRAM powered from the RTC power pin, allowing data to be stored when the rest of the chip is powered off.
    • WatchDog Timer (WDT). The WDT can be clocked from the internal RC oscillator, the RTC oscillator, or the APB clock.
  • Standard Arm test/debug interface for compatibility with existing tools.
  • Emulation trace module supports real-time trace.
  • Single 3.3 V power supply (3.0 V to 3.6 V).
  • Four reduced power modes: idle, sleep, power-down, and deep power-down.
  • Four external interrupt inputs configurable as edge/level sensitive. All pins on PORT0 and PORT2 can be used as edge sensitive interrupt sources.
  • Processor wake-up from Power-down mode via any interrupt able to operate during Power-down mode (includes external interrupts, RTC interrupt, USB activity, Ethernet wake-up interrupt).
  • Two independent power domains allow fine tuning of power consumption based on needed features.
  • Each peripheral has its own clock divider for further power saving.
  • Brownout detect with separate thresholds for interrupt and forced reset.
  • On-chip power-on reset.
  • On-chip crystal oscillator with an operating range of 1 MHz to 25 MHz.
  • 4 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as the system clock. When used as the CPU clock, does not allow CAN and USB to run.
  • On-chip PLL allows CPU operation up to the maximum CPU rate without the need for a high frequency crystal. May be run from the main oscillator, the internal RC oscillator, or the RTC oscillator.
  • Versatile pin function selections allow more possibilities for using on-chip peripheral functions.
