General description

The LPC2210/2220 microcontrollers are based on a 32/16 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 boot-loader 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 A/D converter with conversion time as low as 2.44 μs.

■ Two 32-bit timers (LPC2220 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. On the LPC2220 a Synchronous Serial Port (SSP) with data buffers and variable length transfers can be selected to replace one SPI.

■ 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 I/O pins (5 V tolerant). Up to nine edge or level sensitive external interrupt pins available.

■ 60/75 MHz (LPC2210/2220) 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 30 MHz and with external oscillator up to 50 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.
