General description
The LPC1850/30/20/10 are ARM Cortex-M3 based microcontrollers for embedded applications. The ARM Cortex-M3 is a next generation core that offers system enhancements such as low power consumption, enhanced debug features, and a high level of support block integration.
The LPC1850/30/20/10 operate at CPU frequencies of up to 180 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 LPC1850/30/20/10 include up to 200 kB of on-chip SRAM, a quad SPI Flash Interface (SPIFI), a State Configurable Timer (SCT) subsystem, two High-speed USB controllers, Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals.

FEATUREs and benefits
■ Processor core
   ◆ ARM Cortex-M3 processor, running at frequencies of up to 180 MHz.
   ◆ ARM Cortex-M3 built-in Memory Protection Unit (MPU) supporting eight regions.
   ◆ ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).
   ◆ Non-maskable Interrupt (NMI) input.
   ◆ JTAG and Serial Wire Debug, serial trace, eight breakpoints, and four watch points.
   ◆ Enhanced Trace Module (ETM) and Enhanced Trace Buffer (ETB) support.
   ◆ System tick timer.
■ On-chip memory
   ◆ 200 kB SRAM for code and data use.
   ◆ Multiple SRAM blocks with separate bus access.
   ◆ 64 kB ROM containing boot code and on-chip software drivers.
   ◆ 32-bit One-Time Programmable (OTP) memory for general-purpose use.
■ Clock generation unit
   ◆ Crystal oscillator with an operating range of 1 MHz to 25 MHz.
   ◆ 12 MHz internal RC oscillator trimmed to 1 % accuracy over temperature and
      voltage.
   ◆ Ultra-low power RTC crystal oscillator.
   ◆ Three PLLs allow CPU operation up to the maximum CPU rate without the need for
      a high-frequency crystal. The second PLL is dedicated to the High-speed USB, the
      third PLL can be used as audio PLL.
   ◆ Clock output.
■ Configurable digital peripherals:
   ◆ State Configurable Timer (SCT) subsystem on AHB.
   ◆ Global Input Multiplexer Array (GIMA) allows to cross-connect multiple inputs and
      outputs to event driven peripherals like timers, SCT, and ADC0/1.
■ Serial interfaces:
   ◆ Quad SPI Flash Interface (SPIFI) with 1-, 2-, or 4-bit data at rates of up to
      52 MB per second.
   ◆ 10/100T Ethernet MAC with RMII and MII interfaces and DMA support for high
      throughput at low CPU load. Support for IEEE 1588 time stamping/advanced time
      stamping (IEEE 1588-2008 v2).
   ◆ One High-speed USB 2.0 Host/Device/OTG interface with DMA support and
      on-chip high-speed PHY (USB0).
   ◆ One High-speed USB 2.0 Host/Device interface with DMA support, on-chip
      full-speed PHY and ULPI interface to an external high-speed PHY (USB1).
   ◆ USB interface electrical test software included in ROM USB stack.
   ◆ Four 550 UARTs with DMA support: one UART with full modem interface; one
      UART with IrDA interface; three USARTs support UART synchronous mode and a
      smart card interface conforming to ISO7816 specification.
   ◆ Up to two C_CAN 2.0B controllers with one channel each. Use of C_CAN controller
      excludes operation of all other peripherals connected to the same bus bridge See
      Figure 1 and Ref. 1.
   ◆ Two SSP controllers with FIFO and multi-protocol support. Both SSPs with DMA
      support.
   ◆ One Fast-mode Plus I2C-bus interface with monitor mode and with open-drain I/O
      pins conforming to the full I2C-bus specification. Supports data rates of up to
      1 Mbit/s.
   ◆ One standard I2C-bus interface with monitor mode and standard I/O pins.
   ◆ Two I2S interfaces with DMA support, each with one input and one output. (Continue ...)
