LPC2214 概述

The LPC2214 is based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 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 pct with minimal performance penalty.

With its 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, PWM channels and up to nine external interrupt pins the LPC2214 is particularly suitable for industrial control, medical systems, access control and point-of-sale. Number of available fast GPIOs ranges from up to 76 pins (with external memory) through up to 112 pins (single-chip). With a wide range of serial communications interfaces, the LPC2214 is also very well suited for communication gateways, protocol converters and embedded soft modems as well as many other general-purpose applications.
