The LPC2194 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 % with minimal performance penalty.
With its compact 64-pin package, low power consumption, various 32-bit timers,
4-channel 10-bit ADC, four advanced CAN channels, PWM channels and 46 fast GPIO
lines with up to nine 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 applications that need more than two 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.
Remark: Throughout the data sheet, the term LPC2194 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.
