The LPC2194 is based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation
and embedded trace support, together with 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 its compact 64 pin package, low power consumption, various 32-bit timers,
4-channel 10-bit ADC, 4 advanced CAN channels, PWM channels and 46 GPIO lines
with up to 9 external interrupt pins this microcontroller is particularly suitable for
automotive applications such as a CAN gateway that connects several CAN busses
or a CAN bridge between sub networks at different speeds. Sensors with CAN
interface or debugging via CAN are additional application that need more than 2 CAN
interfaces. It is also an adequate solution for industrial control, medical systems and
fault-tolerant maintenance buses. With a wide range of additional serial
communications interfaces, it is also suited for communication gateways and protocol
converters as well as many other general-purpose applications.
