LPC2880; LPC2888

16/32-bit ARM microcontrollers with external memory interface

• An interrupt to the processor can be generated on DMA completion, when a DMA

channel is halfway to completion, or when a DMA error has occurred.

6.13 UART and IrDA

The LPC2880/LPC2888 contains one UART with baud rate generator and IrDA support.

6.13.1 Features

• 32-B Receive and Transmit FIFOs.

• Register locations conform to the 16C650 industry standard.

• Receiver FIFO trigger points at 1 B, 16 B, 24 B, and 28 B.

• Built-in baud rate generator.

• CGU generates UART clock including fractional divider capability.

• Auto baud capability.

• Optional hardware ﬂow control.

• IrDA mode for infrared communication.

6.14 I2C-bus interface

The LPC2880/LPC2888 I2C-bus interface is byte oriented and has four operating modes:

master Transmit mode, master Receive mode, slave Transmit mode and slave Receive

mode. The interface complies with the entire I2C-bus speciﬁcation, and allows turning

power off to the LPC2880/LPC2888 without causing a problem with other devices on the

same I2C-bus.

6.14.1 Features

• Standard I2C-bus interface, conﬁgurable as Master, Slave, or Master/Slave.

• Arbitration between simultaneously transmitting masters without corruption of serial

data on the bus.

• Programmable clock allows adjustment of I2C-bus transfer rates.

• Bidirectional data transfer between masters and slaves.

• Serial clock synchronization allows devices with different bit rates to communicate via

one serial bus.

• Serial clock synchronization can be used as a handshake mechanism to suspend and

resume serial transfer.

• Supports normal (100 kHz) and fast (400 kHz) operation.

6.15 10-bit A/D converter

The LPC2880/LPC2888 contains a single 10-bit successive approximation analog to

digital converter with ﬁve multiplexed channels.

6.15.1 Features

• 10-bit successive approximation analog to digital converter.

• Input multiplexing among 5 pins.
