The LPC2292/2294 each contain two/four CAN controllers. The CAN is a serial
communications protocol which efficiently supports distributed real-time control with a
very high level of security. Its domain of application ranges from high-speed networks to
low cost multiplex wiring.
The LPC2292/2294 each contain two UARTs. In addition to standard transmit and receive
data lines, the UART1 also provides a full modem control handshake interface.
Compared to previous LPC2000 microcontrollers, UARTs in LPC2292/2294/01 introduce
a fractional baud rate generator for both UARTs, enabling these microcontrollers to
achieve standard baud rates such as 115200 Bd with any crystal frequency above 2 MHz.
In addition, auto-CTS/RTS flow-control functions are fully implemented in hardware.

can operate as either a receiver-only device (e.g., an LCD driver or a transmitter with the
capability to both receive and send information (such as memory). Transmitters and/or

C-bus serial I/O controller
Data rates up to 1 Mbit/s on each bus.
32-bit register and RAM access.
Compatible with CAN specification 2.0B, ISO 11898-1.
Global Acceptance Filter recognizes 11-bit and 29-bit RX identifiers for all CAN buses.
Acceptance Filter can provide FullCAN-style automatic reception for selected
Standard identifiers.
16 B Receive and Transmit FIFOs.
Register locations conform to 16C550 industry standard.
Receiver FIFO trigger points at 1 B, 4 B, 8 B, and 14 B
Built-in fractional baud rate generator covering wide range of baud rates without a
need for external crystals of particular values.
Transmission FIFO control enables implementation of software (XON/XOFF) flow
control on both UARTs.
UART1 is equipped with standard modem interface signals. This module also
provides full support for hardware flow control (auto-CTS/RTS).
Fractional baud rate generator enables standard baud rates such as 115200 Bd to be
achieved with any crystal frequency above 2 MHz.
Auto-bauding.
Auto-CTS/RTS flow-control fully implemented in hardware.
