Technical Summary
The DSP56F801EVM is designed as a versatile Digital Signal Processor, (DSP),
development card for developing real-time software and hardware products to support a
new generation of applications in digital and wireless messaging, servo and motor control,
digital answering machines, feature phones, modems, and digital cameras. The power of
the 16-bit DSP56F801 DSP, combined with the Hall-Effect/Quadrature Encoder interface,
motor zero crossing logic, motor bus over-current logic, motor bus over-voltage logic and
parallel JTAG interface, makes the DSP56F801EVM ideal for developing and
implementing many motor controlling algorithms, as well as for learning the architecture
and instruction set of the DSP56F801 processor.
The main features of the DSP56F801EVM, with board and schematic reference
designators include:
• DSP56F801 16-bit +3.3V Digital Signal Processor operating at 80MHz [U1]
• 8.00MHz crystal oscillator for DSP frequency generation [Y1]
• Optional external oscillator frequency input connector [JG7 and JG8]
• Joint Test Action Group (JTAG) port interface connector for an external debug
Host Target Interface [J8]
• On-board Parallel JTAG Host Target Interface, with a connector for a PC printer
port cable [P2]
• RS-232 interface for easy connection to a host processor [U2 and P4]
• Connector to allow the user to connect their own SCI / MPIO compatible peripheral
[J6]
• Connector to allow the user to connect their own SPI / MPIO compatible peripheral
[J3]
• Connector to allow the user to connect their own PWM or MPIO compatible
peripheral [J1]
• Connector to allow the user to connect their own Timer D/ MPIO compatible
peripheral [J5]
