2.0 The TMS320VC5509 EVM Operation
This chapter describes the VC5509 evaluation module, key components, and how
they operate. It also provides information on the EVM’s various interfaces.The VC5509
EVM consists of five major blocks of logic.
• C5509 external memory
• Analog Interface
• On board Serial I/O interface
• Expansion interface
• JTAG Interface
2.1 The TMS320VC5509 EVM Board
The VC5509 EVM is a 7.0 x 3.45 inch multi-layer board which is powered by an
external +5 volt only power supply. Figure 2-1 shows the top and bottom layout of the
VC5509 EVM.

2.1.1 Power Connector
The VC5509 is powered by a +5 volt only power supply which is available with the
module. The board requires 1 amp. The power is supplied via 2 millimeter jack JP9. If
expansion boards are connected to the module a higher amperage power supply may
be necessary. The board also has a +3.3 and +2.5 volt regulator to provide power to
the lower voltage components.
2.2 TMS320VC5509 Memory Interface

2.2.1 SDRAM Interface
The VC5509 directly interfaces to SDRAM. On the EVM the SDRAM is mapped into the
VC5509’s CE0 space allowing 4 megabytes of on board DRAM. The DRAM is
controlled by on chip control registers. For proper configuration of these registers refer
to the VC5509 demonstration code included with the EVM.
2.2.2 Interface CPLD
The VC5509 uses a CPLD to interface to the Flash ROM, host port, and SPI for the
display. The CPLD is mapped into the CEn address space and contains on 8-bit
extended address register for the Flash Memory, an 8-bit shift register for the SPI
control to the display, and an Address Decoder for the Host Port Interface.
The addresses are defined below for 16 bit access (i.e. (volatile unsigned short *));
2.2.3 Flash ROM
The Flash ROM typically resides in the CE1 space. Since the VC5509 144 pin PGE
package only supplies 12 address lines directly the upper 8 address bits for the Flash
ROM are supplied by the CPLD, U9. At reset these extended address lines are set to 0.
The extended address latch format is shown below.

2.2.4 LCD Interface
The Liquid Crystal Display (LCD) is a write only interface. It is interfaced via an 8-bit
shift register.
Two locations are used to interface the LCD address bit to be directly programmed.
Writing to these locations starts the output to be serialized in an 8 bit sequence to the
display. The shift clock frequency is 3 megahertz.
The address location 0x401800 LCD A0 should = 0. Address location 0x401800 can be
addressed when LCD A0 = 1.
The table below shows the relationship of the DSP data bits to the LCD data bits.
The figure below shows the LCD data transfer timing.
The status of the shift register is put out on GPIO4. When high, the LCD shift register is
busy. When GPIO4 is low the shift register is ready.
2.3 Oscillator Selection
The TMS320VC5509 EVM is equipped with a 24 megahertz oscillator. This oscillator
runs the on board parallel port JTAG controller. This clock is divided by resulting in a
12 megahertz clock which is used to drive the VC5509. This frequency is used to be
compatible with USB timing requirements.
