The Embest Mini44B0 processor card incorporates Samsung's S3C44B0x processor, which is based on a 16/32-bit ARM7TDMI RISC core. The architectural enhancements of ARM7TDMI include the Thumb decompressor, 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 the S3C44B0x. The card can be connected to your carrierboard via a 200-pin DIMM socket (not included). The 16-bit data bus, I/O and all other hardware interfaces are extended to the DIMM. The processor card has no software on itself originally. You can develop the software according to your own designs. S3C44B0x Processor Card Features - Dimensions: 67.6 x 49 mm
- Temperature Range: 0 to +70 Celsius
- Samsung S3C44B0x microcontroller based on a 2.5V Static ARM7TDMI CPU core with 8 KB cache

- On-chip PLL generates the 8 MHz OSC to operate the MCU at up to 66 MHz
- 32.768 kHz Real-Time clock
- JTAG interface
- 16-bit data bus, I/O and all other hardware interface expansions via DIMM 200-pin
- Little/Big endian mode selection support through CPU jumper setting
- Single 3.3V power supply
JTAG Connector The Mini44B0 processor card uses an 8-pin JTAG debug interface to connect to your development system through debug cable or emulator. With 1.0mm pin spacing, the connector measures 11mm long by 4.5mm deep by 3mm high. The pinout is as follows: Pin | Name | Function | 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 accidental 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 accidental triggering. | 7 | GND | GND | 8 | VDD33 | DC3.3V | Download Mini44B0 Card Schematic (PDF file; 42KB) Ships from: China Leadtime: 3 days
