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.

16/32-bit ARM7TDMI-S processor.
