The LPC2880/2888 contains a single 10-bit successive approximation ADC with five
multiplexed channels.
The analog I/O system includes an I
dual ADC, and a dual DAC. Each channel includes a separate 4-sample FIFO.
Each of the two ADC inputs is connected to a Programmable Gain Amplifier (PGA).
Each DAC has two output pins.
The USB is a 4-wire bus that supports communication between a host and a number (127
maximum) of peripherals. The host controller allocates the USB bandwidth to attached
devices through a token based protocol. The bus supports hot plugging, un-plugging and
dynamic configuration of the devices. All transactions are initiated by the host controller.
The host schedules transactions in 1 ms frames. Each frame contains an SOF marker and
transactions that transfer data to/from device endpoints. There are four types of transfers
defined for the endpoints. Control transfers are used to configure the device. Interrupt
transfers are used for periodic data transfer. Bulk transfers are used when rate of transfer
is not critical. Isochronous transfers have guaranteed delivery time but no error correction.

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.
10-bit successive approximation ADC.
Input multiplexing among 5 pins.
Power-down mode.
Measurement range 0 V to 3.3 V.
