General description
The LPC2210/2220 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.
   
Features   
Key features
■ 16/32-bit ARM7TDMI-S microcontroller in a LQFP144 and TFBGA144 package.
■ 16/64 kB on-chip static RAM (LPC2210/2220).
■ 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.
■ Eight channel 10-bit ADC with conversion time as low as 2.44 µs.
    ◆ LPC2210/01 and LPC2220 only: Dedicated result registers for ADC(s) reduce
        interrupt overhead. The ADC pads are 5 V tolerant when configured for digital I/O
        function(s).
■ Two 32-bit timers (LPC2220 and LPC2210/01 also external event counters) with four
    capture and four compare channels, PWM unit (six outputs), Real-Time Clock (RTC),
    and watchdog.
■ Multiple serial interfaces including two UARTs (16C550), Fast I2C-bus (400 kbit/s) and
    two SPIs.
    ◆ LPC2210/01 and LPC2220 only: A Synchronous Serial Port (SSP) with data
        buffers and variable length transfers can be selected to replace one SPI.
    ◆ LPC2210/01 and LPC2220 only: UART0/1 include fractional baud rate generator,
        auto-bauding capabilities, and handshake flow-control fully implemented in
        hardware.
■ 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 pins (5 V tolerant) capable. Up to nine edge/level sensitive
    external interrupt pins available.
    ◆ LPC2210/01 and LPC2220 only: Fast GPIO ports enable port pin toggling up to 3.5
        times faster than the original device. They also allow for a port pin to be read at any
        time regardless of its function.
■ 60 MHz (LPC2210) and 75 MHz (LPC2210/01 and LPC2220) maximum CPU clock
    available from programmable on-chip Phase-Locked Loop (PLL) with settling time of
    100 µs.
■ On-chip integrated oscillator operates with external crystal in range of 1 MHz to
    25 MHz and with external oscillator up to 25 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 %) with 5 V tolerant I/O pads.
