LPC2378
Fast communication chip
I
Serial Interfaces:
N
Ethernet MAC with associated DMA controller. These functions reside on an
independent AHB bus.
N
USB 2.0 full-speed device with on-chip PHY and associated DMA controller.
N
Four UARTs with fractional baud rate generation, one with modem control I/O, one
with IrDA support, all with FIFO.
N
CAN controller with two channels.
N
SPI controller.
N
Two SSP controllers, with FIFO and multi-protocol capabilities. One is an alternate
for the SPI port, sharing its interrupt and pins. These can be used with the GPDMA
controller.
N
Three I
2
C-bus interfaces (one with open-drain and two with standard port pins).
N
I
2
S (Inter-IC Sound) interface for digital audio input or output. It can be used with
the GPDMA.
I
Other peripherals:
N
SD/MMC memory card interface.
N
104 General purpose I/O pins with configurable pull-up/down resistors.
N
10-bit ADC with input multiplexing among 8 pins.
N
10-bit DAC.
N
Four general purpose timers/counters with 8 capture inputs and 10 compare
outputs. Each timer block has an external count input.
N
One PWM/timer block with support for three-phase motor control. The PWM has
two external count inputs.
N
Real-Time Clock (RTC) with separate power pin, clock source can be the RTC
oscillator or the APB clock.
N
2 kB SRAM powered from the RTC power pin, allowing data to be stored when the
rest of the chip is powered off.
N
WatchDog Timer (WDT). The WDT can be clocked from the internal RC oscillator,
the RTC oscillator, or the APB clock.
I
Standard ARM test/debug interface for compatibility with existing tools.
I
Emulation trace module supports real-time trace.
I
Single 3.3 V power supply (3.0 V to 3.6 V).
I
Four reduced power modes: idle, sleep, power down, and deep power down.
I
Four external interrupt inputs configurable as edge/level sensitive. All pins on PORT0
and PORT2 can be used as edge sensitive interrupt sources.
I
Processor wake-up from Power-down mode via any interrupt able to operate during
Power-down mode (includes external interrupts, RTC interrupt, USB activity, Ethernet
wake-up interrupt).
I
Two independent power domains allow fine tuning of power consumption based on
needed features.
I
Each peripheral has its own clock divider for further power saving.
I
Brownout detect with separate thresholds for interrupt and forced reset.
I
On-chip power-on reset.
I
On-chip crystal oscillator with an operating range of 1 MHz to 24 MHz.
I
4 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as
the system clock. When used as the CPU clock, does not allow CAN and USB to run.
