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.
