16/32-bit Arm® microcontrollers; flashless, with 10-bit ADC and external memory interface

Overview

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 pct with minimal performance penalty.

With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, PWM channels, and up to nine external interrupt pins these microcontrollers are particularly suitable for industrial control, medical systems, access control and point-of-sale. The LPC2210/2220 can provide up to 76 GPIOs depending on bus configuration. With a wide range of serial communications interfaces, it is also very well suited for communication gateways, protocol converters and embedded soft modems as well as many other general-purpose applications.

Remark:Throughout the data sheet, the term LPC2210/2220 will apply to devices with and without the /01 suffix. The /01 suffix will be used to differentiate LPC2210 devices only when necessary.

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 us.
- 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 us.
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 pct) with 5 V tolerant I/O pads. 16/32-bit ARM7TDMI-S^™ processor.
