LPC2212/LPC2214
16/32-bit ARM microcontrollers; 128/256 kB ISP/IAP Flash
with 10-bit ADC and external memory interface
Rev. 02 — 23 December 2004
Product data
1. General 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.
2. Features
2.1 Key features
s
16/32-bit ARM7TDMI-S microcontroller in a LQFP144 package.
s
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.
s
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.
s
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.
s
