The LPC4350-DB1 evaluation board allows you to quickly prototype the embedded applications. This development board is based on the LPC4350FET256 dual core ARM Cortex-M4 & Cortex-M0 MCU.
The LPC4350FET256 microcontroller comes without an internal flash memory. You can use an external 16MBit flash to store your firmware. The external flash is assembled on all LPC4350-DB1 board modifications. If you need a microcontroller with internal flash, take a look at our LPC4357-DB1 evaluation board.
The LPC4350-DB1 development board is available in several modifications. Some of the modifications contain external 64 Mbit SDRAM and/or assembled side connectors.
There are many optional extension boards, that can be attached to the LPC4350-DB1 side connectors.
In addition to all the LPC4350-DB1 demoboard components LPC4350-DB1-A evaluation board contains assembled connectors and plastic legs. You can use the side connectors to connect wide range of compatible extension boards (see below).
The LPC4350-DB1-A modification of development board suites for software engineers, who need to evaluate the extended functionality of LPC4350-FET256 dual-core (Cortex-M4 + Cortex-M0) micro-controller, but don't want to bother with soldering.
LPC4350-DB1 Development Board Components
The LPC4350-DB1 development board contains most of the extensively used components. Its peripheral support can be easily extended by the LPC4350-DB1 PCB soldering options and wide range of extension boards.
The LPC4350-DB1 evaluation board hardware components are:
- LPC4350FET256 - dual-core ARM Cortex-M4 DSP controller with Cortex-M0 coprocessor.
- USB 2.0 High-speed interface - with mini USB type-B connector.
- 10/100MBit Ethernet interface - LPC4350-DB1 evaluation board contains assembled external PHY and connector.
- ARM Standard JTAG/SWD connector - 20-pin 2.54mm (0.1 inch)
- External NOR flash - 16MB Spansion S29AL016J70TFI01
- 4 user push-buttons + reset button
- 5 user controlled LEDs - 4 green LEDs + 1 red LED
- Boot select jumpers
LPC4350-DB1 PCB Soldering Options
LPC4350-DB1 evaluation board can be extended by soldering the following components:
- External SDRAM - we have tested the board with Micron MT48LC4M32B2-7 Synchronous DRAM.
- Real-Time Clock (RTC) - there are placeholder for RTC crystal and connection points for external power supply.
- Cortex Debug Connector - the small and low cost 10-pin 1.27mm (0.05 inch) connector can be assembled to access SWD, SWV, and JTAG signals available on Cortex-M4 and Cortex-M0 processors.
- Cortex Debug + ETM Connector - this small 20-pin 1.27mm (0.05 inch) connector can be assembled to access SWD, SWV, JTAG, and ETM (4-bit) signals available on Cortex-M4 and Cortex-M0 processors.
The LPC4350 Demoboard has JTAG connector. This connector can be used for debugging process. On the Demoboard J-TAG connector is pointed as the J1.
Also additional debug J-TAG/SWD and Cortex Debug+ETM connectors can be soldered:
Serial Wire Debug (SWD) provides a debug port for severely pin limited packages, often the case for small package microcontrollers but also complex ASICs where limiting pin-count is critical and can be the controlling factor in device costs.
SWD replaces the 5-pin JTAG port with a clock + single bi-directional data pin, providing all the normal JTAG debug and test functionality plus real-time access to system memory without halting the processor or requiring any target resident code. SWD uses an ARM standard bi-directional wire protocol, defined in the ARM Debug Interface v5, to pass data to and from the debugger and the target system in a highly efficient and standard way. As a standard interface for ARM processor-based devices, the software developer can count on a wide choice of interoperable tools.
The Cortex Debug+ETM connector interface can access the Embedded Trace Macrocell (ETM) TRACECLK and TRACEDATA signals. The four TRACEDATA signals provide a high-speed data path for capturing instructions.
