LPC2290

16/32-bit ARM microcontroller with external memory interface

• All I/O default to inputs after reset.

6.7.2 Fast I/O features available in LPC2290/01 only

• Fast I/O registers are located on the ARM local bus for the fastest possible I/O timing.

• All GPIO registers are byte addressable.

• Entire port value can be written in one instruction.

• Mask registers allow single instruction to set or clear any number of bits in one port.

6.8 10-bit ADC

The LPC2290 each contain a single 10-bit successive approximation ADC with eight

multiplexed channels.

6.8.1 Features

• Measurement range of 0 V to 3.3 V.

• Capable of performing more than 400000 10-bit samples per second.

• Burst conversion mode for single or multiple inputs.

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

6.8.2 ADC features available in LPC2290/01 only

• Every analog input has a dedicated result register to reduce interrupt overhead.

• Every analog input can generate an interrupt once the conversion is completed.

6.9 CAN controllers and acceptance ﬁlter

The LPC2290 contains two 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.

6.9.1 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-bit and 29-bit RX identiﬁers for all CAN buses.

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

Standard identiﬁers.

• Full CAN messages can generate interrupts.

6.10 UARTs

The LPC2290 contains two UARTs. In addition to standard transmit and receive data

lines, UART1 also provides a full modem control handshake interface.

6.10.1 Features

• 16 B Receive and Transmit FIFOs.
