2. Introduction The Crystalfontz CFA10098 is a breakout and audio amplification board intended for development use with Crystalfontz FT8xx EVE accelerated TFT displays.

This board provides easy to use 0.1-in header pins ideal for testing, prototyping and one-off use with microcontroller based boards and other host interfaces.

Example source-code for the attached EVE accelerated TFT display product is provided on our website.

3. Key Features

• Easy to use 0.1 inch header pins

• 30 position connector for flat-cable connection to the Crystalfontz EVE accelerated displays

• Jumper configurable power and audio options

• EVE compatible PWM audio filter and 2W Class D speaker amplifier

6. Jumper Locations and Functions

6.1. Power Steering Jumpers

By default, backlight and audio amplifier power is sourced from pin-1 on the JHOST header (typically 3.3V).

If a separate power supply is required for the display backlight, open the BL=3v3 jumper link, then use the BL_PWR header pins to supply power (see note 1).

If a separate power supply is required for the speaker audio amplifier, open the AUD=3v3 jumper link, then use the AUD_PWR header pins to supply power (see note 1).

Note: 1. 0.1 inch headers may need to be soldered on the board to access these power connections

power steering jumper locations

6.2. Audio Amplifier Configuration

By default, the audio amplifier is supplied 3.3V from the logic power supply:

• SWBYP = closed

• SWEN = open

• SWTOAUD = open

There is an experimental 3.3v to 5v 500mA boost supply on the 10098. This circuit may be useful for higher impedance loads, or to isolate the audio supply from a noisy 3.3v main supply. To enable the experimental 3.3v to 5v 500mA boost supply:

• SWBYP = open

• SWEN = closed

• SWTOAUD = closed

This section can be enabled to allow the 3.3v main supply

to be switched up to 5.25v for the audio amplifier. The

current is limited to 500mA. This might be useful for:

1) larger output swing for higher impedance loads

2) isolation of the audio supply from a noisy 3.3v supply
