SN8F5940 Starter-Kit

1 Overview of Starter Kit
SN8F5949 Starter-Kit provides easy-development platform. It includes SN8F5940 family real chip and I/O connectors to input signal or drive device of user's application. It is a simple platform to develop application as target board not ready. The Starter-Kit can be replaced by target board, because SN8F5940 family integrates embedded ICE in-circuit debugger circuitry.

1.1 Development Environment
SN8F5949 debug tool cooperate with Keil C51 which includes integrated development environment (IDE, Keil Vision), C51/A51 compliers and BL51 linker. See detailed documentation of SN8F5000 Debug Tool Manual (download on www.sonix.com.tw).

1.2 Development Environment
These configurations must be setup completely before starting Starter-Kit developing.
1. Confirm to the circuit board whether elements are complete.
2. The power source of Starter-Kit circuit is chosen from 5.0V, 3.3V or external power via jumper.
3. The power source comes from 5.0V or 3.3V which must be connect to DC 7.5V power adapter.
4. If the power source is chosen from external power, then external power source connects to EXT pin.
5. The "XIN" pin and the "XOUT" pin need to connect crystal/resonator oscillator components when timer clock is setting X'tal or T0 Timer setting RTC mode.
6. The Debug port can connect SN-LINK adapter for emulation or download code.
7. The MCU LED will light up and SN8F5940 family chip will be connected to power when power (VDD) is switched on.
