1. General description
The LPC2114/2124 are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation
and embedded trace support, together with 128/256 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 % 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 fast GPIO lines with up to nine 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.
Remark: Throughout the data sheet, the term LPC2114/2124 will apply to devices with
and without the /00 or /01 suffixes. The /00 or the /01 suffix will be used to differentiate
from other devices only when necessary.
2. Features and benefits
2.1 Key features brought by LPC2114/2124/01 devices
Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original device.
They also allow for a port pin to be read at any time regardless of its function.
Dedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are
5 V tolerant when configured for digital I/O function(s).
UART0/1 include fractional baud rate generator, auto-bauding capabilities and
handshake flow-control fully implemented in hardware.
Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.
SPI programmable data length and master mode enhancement.
Diversified Code Read Protection (CRP) enables different security levels to be
implemented. This feature is available in LPC2114/2124/00 devices as well.
General purpose timers can operate as external event counters.
