LPC236x microcontroller

• 32-bit ARM7TDMI core running at up to 72MHz clock
• 128 to 512kB In System Programmable Flash memory
• 8/32 kB of SRAM on the ARM local bus for high performance CPU access
• 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM
• 8 kB SRAM for general purpose DMA use also accessible by the USB
• 2 kB SRAM powered from the RTC power pin, allowing data to be stored when the
  rest of the chip is powered off
• In system programming through JTAG or RS232 interface
• Dual Advanced High-performance Bus (AHB) system that provides for simultaneous Ethernet DMA, USB DMA, and program execution from on-chip flash with no contention between those functions
• General Purpose AHB DMA controller (GPDMA) that can be used with the SSP serial interfaces, the I2S port, and the Secure Digital/Multi Media Card (SD/MMC) card port, as well as for memory-to-memory transfers
• Four general purpose timers/counters with total of 8 capture inputs and 10 compare outputs
• One PWM/timer block with support for three-phase motor control
• Ethernet MAC
• USB 2.0 device (full speed)
• CAN controller with two channels
• Four UARTs with fractional baud rate generation, one with modem control I/O, one with IrDA support, all with FIFO
• Three I2C-bus interfaces
• SPI controller
• I2S (Inter-IC Sound) interface for digital audio input or output
• Two SSP controllers, with FIFO and multi-protocol capabilities
• SD/MMC memory card interface (LPC2368 only)
• 10-bit ADC with input multiplexing among 6 pins
• 10-bit DAC
• Up to 70 I/O lines with 5V level support
• Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts
• Four reduced power modes: idle, sleep, power down, and deep power down
• Real-Time Clock (RTC) with separate power pin
• Single 3.3 V power supply (internal 1.8V regulator)
• JTAG interface
   

Ethernet PHY DP83848

• IEEE 802.3u PCS, 100BASE-TX transceivers and filters
• Low power consumption < 270mW typical
• Low power modes
• Optimized for cable length performance far exceeding IEEE specifications 

Block Diagram 

A block diagram of MMlpc236x minimodule is shown on the image below:

All signals of the module are led to two 40-pin terminals with 0.1'' (2.54mm) pitch, which simplifies designing of base boards and allows use of module with prototype boards.
