LPC1759/58/56/54/52/51
32-bit ARM Cortex-M3 microcontroller
„ Multilayer AHB matrix interconnect provides a separate bus for each AHB master.
AHB masters include the CPU, General Purpose DMA controller, Ethernet MAC
(LPC1758 only), and the USB interface. This interconnect provides communication
with no arbitration delays.
„ Split APB bus allows high throughput with few stalls between the CPU and DMA.
„ Serial interfaces:
‹ On the LPC1758 only, Ethernet MAC with RMII interface and dedicated DMA
controller.
‹ USB 2.0 full-speed device/Host/OTG controller with dedicated DMA controller and
on-chip PHY for device, Host, and OTG functions. The LPC1752/51 include a USB
device controller only.
‹ Four UARTs with fractional baud rate generation, internal FIFO, and DMA support.
One UART has modem control I/O and RS-485/EIA-485 support, and one UART
has IrDA support.
‹ CAN 2.0B controller with two (LPC1759/58/56) or one (LPC1754/52/51) channels.
‹ SPI controller with synchronous, serial, full duplex communication and
programmable data length.
‹ Two SSP controllers with FIFO and multi-protocol capabilities. The SSP interfaces
can be used with the GPDMA controller.
‹ Two I²C-bus interfaces supporting fast mode with a data rate of 400 kbit/s with
multiple address recognition and monitor mode.
‹ On the LPC1759/58/56 only, I²S (Inter-IC Sound) interface for digital audio input or
output, with fractional rate control. The I²S-bus interface can be used with the
GPDMA. The I²S-bus interface supports 3-wire and 4-wire data transmit and
receive as well as master clock input/output.
„ Other peripherals:
‹ 52 General Purpose I/O (GPIO) pins with configurable pull-up/down resistors. All
GPIOs support a new, configurable open-drain operating mode. The GPIO block is
accessed through the AHB multilayer bus for fast access and located in memory
such that it supports Cortex-M3 bit banding and use by the General Purpose DMA
Controller.
‹ 12-bit Analog-to-Digital Converter (ADC) with input multiplexing among six pins,
conversion rates up to 200 kHz, and multiple result registers. The 12-bit ADC can
be used with the GPDMA controller.
‹ On the LPC1759/58/56/54 only, 10-bit Digital-to-Analog Converter (DAC) with
dedicated conversion timer and DMA support.
‹ Four general purpose timers/counters, with a total of three capture inputs and ten
compare outputs. Each timer block has an external count input. Specific timer
events can be selected to generate DMA requests.
‹ One motor control PWM with support for three-phase motor control.
‹ Quadrature encoder interface that can monitor one external quadrature encoder.
‹ One standard PWM/timer block with external count input.
‹ Real-Time Clock (RTC) with a separate power domain and dedicated RTC
oscillator. The RTC block includes 20 bytes of battery-powered backup registers.
‹ Watchdog Timer (WDT). The WDT can be clocked from the internal RC oscillator,
the RTC oscillator, or the APB clock.
‹ ARM Cortex-M3 system tick timer, including an external clock input option.
