from 3.3 V or 5 V.

- Digital logic core operates from 2.5 V,

3.3 V or 5 V.

• Small 28-pin SSOP package.

- Total footprint 8 mm x 10 mm plus three

bypass capacitors.

1.4 Configuration Interface

• Configuration from microcontroller or stand-

alone boot EEPROM.

- Microcontroller boot permits reconfigura-

tion during operation.

- EEPROM boot sets a fixed operational con-

figuration.

• Configuration commands written through the

serial interface. (See Table 1)

- Standardized microcontroller interface us-

ing SPI™ registers. (See Table 3)

- Commands write digital filter registers and

FIR / IIR filter coefficients.

- Digital filter registers set hardware config-

uration options.
