LPC2214

Features:

· 16/32-bit ARM7TDMI-S microcontroller in a LQFP144 package.
· 16 kB on-chip Static RAM and 128/256 kB on-chip Flash Program Memory. 128-bit wide interface/accelerator enables high speed 60 MHz operation.
· In-System Programming (ISP) and In-Application Programming (IAP) via on-chip boot-loader software. Flash programming takes 1 ms per 512 byte line. Single sector or full chip erase takes 400 ms.
· 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 ms.
· Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs), Real Time Clock and Watchdog.
· Multiple serial interfaces including two UARTs (16C550), Fast I2C (400 kbits/s) and two SPIs.
· Vectored Interrupt Controller 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 112 general purpose I/O pins (5 V tolerant). Up to 9 edge or level sensitive external interrupt pins available.

Description

·The LPC2212/LPC2214 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation and embedded trace support, together with 128/256 kilobytes (kB) of embedded high speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size applications, the alternative 16-bit Thumb® Mode reduces code by more than 30 % 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 9 external interrupt pins these microcontrollers are particularly suitable for industrial control, medical systems, access control and point-of-sale. Number of available GPIOs ranges from 76 (with external memory) through 112 pins (single-chip). With a wide range of serial communications interfaces, they are also very well suited for communication gateways, protocol converters and embedded soft modems as well as many other general-purpose applications.
