    2/Tính năng:

    Trên board là Chip ARM7 LPC2148 của NXP, có các tính năng nổi trội sau:
    - 16-bit/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.
    - 8 kB to 40 kB of on-chip static RAM and 32 kB to 512 kB of on-chip flash memory.
    128-bit wide interface/accelerator enables high-speed 60 MHz operation.
    - In-System Programming/In-Application Programming (ISP/IAP) via on-chip boot
    loader software. Single flash sector or full chip erase in 400 ms and programming of
    256 bytes in 1 ms.
    - EmbeddedICE RT and Embedded Trace interfaces offer real-time debugging with the
    on-chip RealMonitor software and high-speed tracing of instruction execution.
    - USB 2.0 Full-speed compliant device controller with 2 kB of endpoint RAM.
    In addition, the LPC2146/48 provides 8 kB of on-chip RAM accessible to USB by DMA.
    - One or two (LPC2141/42 vs. LPC2144/46/48) 10-bit ADCs provide a total of 6/14
    analog inputs, with conversion times as low as 2.44 ms per channel.
    - Single 10-bit DAC provides variable analog output (LPC2142/44/46/48 only).
    - Two 32-bit timers/external event counters (with four capture and four compare
    channels each), PWM unit (six outputs) and watchdog.
    - Low power Real-Time Clock (RTC) with independent power and 32 kHz clock input.
    Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s),
    SPI and SSP with buffering and variable data length capabilities.
    - Vectored Interrupt Controller (VIC) with configurable priorities and vector addresses.
    - Up to 45 of 5 V tolerant fast general purpose I/O pins in a tiny LQFP64 package.
    - Up to 21 external interrupt pins available.
    - 60 MHz maximum CPU clock available from programmable on-chip PLL with settling
    time of 100 ms.
    - On-chip integrated oscillator operates with an external crystal from 1 MHz to 25 MHz.
    - Power saving modes include Idle and Power-down.
    - Individual enable/disable of peripheral functions as well as peripheral clock scaling for
    additional power optimization.
    - Processor wake-up from Power-down mode via external interrupt or BOD.
    - Single power supply chip with POR and BOD circuits:
    - CPU operating voltage range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5 V tolerant I/O
    pads.
