Description

The Embest Mini44B0™ processor card is designed especially for user's special integration. The tiny board integrates Samsung's S3C44B0x processor, which is based on a 16/32-bit ARM7TDMI RISC processor. The architectural enhancements of ARM7TDMI include the Thumb decompressor, an on-chip ICE breaker debug support and a 32-bit hardware multiplier. The processor card takes full advantage of the integrated on-chip functions and the peripherals of S3C44B0x. Users can connect the processor card and your carrierboard through DIMM 200-pin. 16-bit data bus, I/O and all other hardware interfaces all expand via DIMM 200-pin. The fully expansion can be used adapted to customer requirements.

The Embest Mini44B0 processor card has no software on itself originally. Customers can develop the software according to their own designs. Embest now also offers professional custom software development and you can leverage our experience to increase your own productivity. The optimal embedded microprocessor solution provides the users with a flexible development environment based on S3C44B0x and a shortened development timeframe.

Layout and Function Block Diagram

JTAG debug interface pin explanation

Embest Mini44B0 processor card uses a standard JTAG debug interface to connect to your development system through debug cable or emulator for debugging. Detailed pin explanation is as following:

Pin	Name	Function explanation
1	TMS	JTAG debug interface mode selecting, a 10k pull-up resistor is needed
2	TDO	JTAG debug interface data output
3	TDI	JTAG debug interface data input
4	TCK	JTAG debug interface clock input
5	nTRST	JTAG reset, pull-up resistor is needed to avoid mistaken triggering
6	nRESET	Reset signal of ARM kernel. For target system reset, reset status checking. Added pull-up resistor on carrierboard is needed to avoid mistaken triggering.
7	GND	GND
8	VDD33	DC3.3V

DIMM 200_pin

Embest Mini44B0 processor card is connected to carrierboard via DIMM 200-pin to plug into a SO-DIMM socket 200-pin which is mounted on your carrierboard for DDR Module.
