Microchips And Integrated Circuits LPC1752FBD80 32- bit ARM Cortex
- M3 microcontroller
General description
The LPC1766 is an ARM Cortex-M3 based microcontroller for embedded
applications featuring a high level of integration and low power
consumption. The ARM Cortex-M3 is a next generation core that
offers system enhancements such as enhanced debug features and a
higher level of support block integration.
The LPC1766 operates at CPU frequencies of up to 80 MHz. The ARM
Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard
architecture with separate local instruction and data buses as well
as a third bus for peripherals. The ARM Cortex-M3 CPU also includes
an internal prefetch unit that supports speculative branching.
The peripheral complement of the LPC1766 includes 256 kB of flash
memory, 64 kB of data memory, Ethernet MAC, USB Device/Host/OTG
interface, 8-channel general purpose DMA controller, 4 UARTs, 2 CAN
channels, 2 SSP controllers, SPI interface, 3 I 2C interfaces,
2-input plus 2-output I2S interface, 8 channel 12-bit ADC, 10-bit
DAC, motor control PWM, Quadrature Encoder interface, 4 general
purpose timers, 6-output general purpose PWM, ultra-low power RTC
with separate battery supply, and up to 70 general purpose I/O
pins.
The LPC1766 is pin-compatible to the LPC2366 ARM7-based
microcontroller.
Features

A Memory Protection Unit (MPU) supporting eight regions is
included.

- 256 kB on-chip flash programmimg memory. Enhanced flash memory
accelerator enables high-speed 80 MHz operation with zero wait
states.

- 64 kB on-chip SRAM includes:
- 32 kB of SRAM on the CPU with local code/data bus for
high-performance CPU access.
- Two 16 kB SRAM blocks with separate access paths for higher
throughput. These SRAM blocks may be used for Ethernet, USB, and
DMA memory, as well as for general purpose CPU instruction and data
storage.
- Eight channel General Purpose DMA controller (GPDMA) on the AHB
multilayer matrix that can be used with the SSP, I2S, UART, the
Analog-to-Digital and Digital-to-Analog converter peripherals,
timer match signals, and for memory-to-memory transfers.
- Multilayer AHB matrix interconnect provides a separate bus for each
AHB master. AHB masters include the CPU, General Purpose DMA
controller, Ethernet MAC, 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:
- 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.
- Four UARTs with fractional baud rate generation, internal FIFO, DMA
support, and RS-485 support. One UART has modem control I/O, and
one UART has IrDA support.
- CAN 2.0B controller with two channels.
- SPI controller with synchronous, serial, full duplex communication
and programmable data leCM GROUPh.
- 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
kbits/s with multiple address recognition and monitor mode.
- One I2C-bus interface supporting full I2C-bus specification and fast mode
plus with a data rate of 1 Mbit/s with multiple address recognition
and monitor mode.
- I 2S (Inter-IC Sound) interface for digital audio input or output,
with fractional rate control. The I2S interface can be used with
the GPDMA. The I2S interface supports 3-wire and 4-wire data
transmit and receive as well as master clock input/output.
- Other peripherals:
- 70 General Purpose I/O (GPIO) pins with configurable pull-up/down
resistors and a new, configurable open-drain operating mode.
- 12-bit Analog-to-Digital Converter (ADC) with input multiplexing
among eight pins, conversion rates up to 1 MHz, and multiple result
registers. The 12-bit ADC can be used with the GPDMA controller.
- 10-bit Digital-to-Analog Converter (DAC) with dedicated conversion
timer and DMA support.
- Four general purpose timers/counters, with a total of eight capture
inputs and ten compare outputs. Each timer block has an external
count input and DMA support.
- 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 64 bytes of battery-powered
backup registers.
- Watchdog Timer (WDT) resets the microcontroller within a reasonable
amount of time if it enters an erroneous state.
- System tick timer, including an external clock input option.
- Repetitive interrupt timer provides programmable and repeating
timed interrupts.
- Each peripheral has its own clock divider for further power
savings.
- Standard JTAG test/debug interface for compatibility with existing
tools. Serial Wire Debug and Serial Wire Trace Port options.
- Emulation trace module enables non-intrusive, high-speed real-time
tracing of instruction execution.
- Integrated PMU (Power Management Unit) automatically adjusts
internal regulators to minimize power consumption during Sleep,
Deep sleep, Power-down, and Deep power-down modes.
- Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deep
power-down.
- Single 3.3 V power supply (2.4 V to 3.6 V).
- Four external interrupt inputs configurable as edge/level
sensitive. All pins on PORT0 and PORT2 can be used as edge
sensitive interrupt sources.
- Non-maskable Interrupt (NMI) input.
- Clock output function that can reflect the main oscillator clock,
IRC clock, RTC clock, CPU clock, and the USB clock.
- The Wakeup Interrupt Controller (WIC) allows the CPU to
automatically wake up from any priority interrupt that can occur
while the clocks are stopped in deep sleep, power-down, and deep
power-down modes.
- Processor wake-up from Power-down mode via interrupts from various
peripherals.
- Brownout detect with separate threshold for interrupt and forced
reset.
- Power-On Reset (POR).
- Crystal oscillator with an operating range of 1 MHz to 24 MHz.
