LPC2377/78

Single-chip 16-bit/32-bit microcontroller

that the recognition of received Identiﬁers, known in CAN terminology as Acceptance

Filtering, has been removed from the CAN controllers and centralized in a global

Acceptance Filter.

7.12.1 Features

• Two CAN controllers and buses.

• Data rates 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 receive identiﬁers for all CAN

buses.

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

Standard Identiﬁers.

• Full CAN messages can generate interrupts.

7.13 10-bit ADC

The LPC2377/78 contains one ADC. It is a single 10-bit successive approximation ADC

with eight channels.

7.13.1 Features

• 10-bit successive approximation ADC

• Input multiplexing among 8 pins

• Power-down mode

• Measurement range 0 V to Vi(VREF)

• 10-bit conversion time

≥ 2.44 µs

• Burst conversion mode for single or multiple inputs

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

• Individual result registers for each ADC channel to reduce interrupt overhead

7.14 10-bit DAC

The DAC allows the LPC2377/78 to generate a variable analog output. The maximum

output value of the DAC is Vi(VREF).

7.14.1 Features

• 10-bit DAC

• Resistor string architecture

• Buffered output

• Power-down mode

• Selectable output drive
