LPC2377/78
Single-chip 16-bit/32-bit microcontrollers
 General Purpose DMA controller (GPDMA) on AHB that can be used with the SSP
serial interfaces, the I
2
S port, and the Secure Digital/MultiMediaCard (SD/MMC) card
port, as well as for memory-to-memory transfers.
 Serial Interfaces:
 Ethernet MAC with associated DMA controller. These functions reside on an
independent AHB.
 USB 2.0 full-speed device with on-chip PHY and associated DMA controller
(LPC2378 only).
 Four UARTs with fractional baud rate generation, one with modem control I/O, one
with IrDA support, all with FIFO.
 CAN controller with two channels (LPC2378 only).
 SPI controller.
 Two SSP controllers with FIFO and multi-protocol capabilities. One is an alternate
for the SPI port, sharing its interrupt and pins. These controllers can be used with
the GPDMA controller.
 Three I
2
C-bus interfaces (one with open-drain and two with standard port pins).
 I
2
S (Inter-IC Sound) interface for digital audio input or output. It can be used with
the GPDMA.
 Other peripherals:
 SD/MMC memory card interface.
 104 General purpose I/O pins with configurable pull-up/down resistors.
 10-bit ADC with input multiplexing among 8 pins.
 10-bit DAC.
 Four general purpose timers/counters with 8 capture inputs and 10 compare
outputs. Each timer block has an external count input.
 One PWM/timer block with support for three-phase motor control. The PWM has
two external count inputs.
 Real-Time Clock (RTC) with separate power pin, clock source can be the RTC
oscillator or the APB clock.
 2 kB SRAM powered from the RTC power pin, allowing data to be stored when the
rest of the chip is powered off.
 WatchDog Timer (WDT). The WDT can be clocked from the internal RC oscillator,
the RTC oscillator, or the APB clock.
 Standard ARM test/debug interface for compatibility with existing tools.
 Emulation trace module supports real-time trace.
 Single 3.3 V power supply (3.0 V to 3.6 V).
 Four reduced power modes: idle, sleep, power-down, and deep power-down.
 Four external interrupt inputs configurable as edge/level sensitive. All pins on Port 0
and Port 2 can be used as edge sensitive interrupt sources.
 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).
 Two independent power domains allow fine-tuning of power consumption based on
needed features.
 Each peripheral has its own clock divider for further power saving.
 Brownout detect with separate thresholds for interrupt and forced reset.
 On-chip power-on reset.
