6.10.1

Features

• Direction control of individual bits.

• Separate control of output set and clear.

• All I/O default to inputs after reset.

6.11 10-bit A/D converter

The LPC2290 contains single 10-bit successive approximation analog to digital

converter with eight multiplexed channels.

6.11.1

Features

• Measurement range of 0 V to 3 V.

• Capable of performing more than 400,000 10-bit samples per second.

• Burst conversion mode for single or multiple inputs.

• Optional conversion on transition on input pin or Timer Match signal.

6.12 CAN controllers and acceptance ﬁlter

The LPC2290 contains two CAN controllers. The Controller Area network (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.

6.12.1

Features

• 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 and 29-bit Rx identiﬁers for all CAN buses.

• Acceptance Filter can provide FullCAN-style automatic reception for selected

Standard identiﬁers.

6.13 UARTs

The LPC2290 contains two UARTs. One UART provides a full modem control

handshake interface, the other provides only transmit and receive data lines.

6.13.1

Features

• 16 byte Receive and Transmit FIFOs.

• Register locations conform to ‘550 industry standard.

• Receiver FIFO trigger points at 1, 4, 8, and 14 bytes

• Built-in baud rate generator.

• Standard modem interface signals included on UART1.
