Product data
1. General description
The LPC2114/LPC2124 are based on a 16/32 bit ARM7TDMI-S鈩?CPU with real-time
emulation and embedded trace support, together with 128/256 kilobytes (kB) of
embedded high speed 鏗俛sh 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鈩?Mode reduces code by
more than 30 % with minimal performance penalty.
With their compact 64 pin package, low power consumption, various 32-bit timers,
4-channel 10-bit ADC, PWM channels and 46 GPIO lines with up to 9 external
interrupt pins these microcontrollers are particularly suitable for industrial control,
medical systems, access control and point-of-sale. 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 tiny LQFP64 package.
s
16 kB on-chip Static RAM.
s
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 interface enables breakpoints and watch points. Interrupt
service routines can continue to execute whilst the foreground task is debugged
with the on-chip RealMonitor鈩?software.
s
Embedded Trace Macrocell鈩?enables non-intrusive high speed real-time tracing
of instruction execution.
s
Four channel 10-bit A/D converter with conversion time as low as 2.44
碌s.
