11

— 4 × 12-bit ADC resolution

— Programmable resolution for increased conversion speed (12-bit, 10-bit, 8-bit)

– 12-bit conversion time as low as1 µS (as fast as 1 M sample/sec)

– 10-bit conversion time as low as 867 nS (as fast as 1.2 M sample/sec)

– 8-bit conversion time as low as 733 nS (as fast as 1.4 M sample/sec)

— Accuracy as high as 10-bit accuracy at 500 K sample/sec and 8-bit accuracy at 1 M sample/sec

— Differential conversions

— Single-ended signal range from 0 to 5 V

— Variable gain amplifiers on differential inputs (×1, ×2, ×4)

— Sample times of 2 (default), 8, 64, or 128 ADC clock cycles

— Provides time stamp information when requested

— Supports both right-justified unsigned and signed formats for conversion results

•

64 input channels, including 16 channels which can each be converted simultaneously by each

eQADC

•

Eight additional internal channels for measuring control and monitoring voltages inside the device

— Including core voltage, I/O voltage, and low-voltage interrupt (LVI) voltages

•

As many as eight inputs can be configured as four pairs of differential analog input channels

— Programmable pull-up/pull-down resistors on each differential input

•

Silicon die temperature sensor

— Provides temperature of silicon as an analog value

— Read using an internal ADC analog channel

•

Four decimation filters

— Programmable decimation factor (2 to 16)

— Selectable IIR or FIR filter

— Fully programmable 4th order IIR or 8th order FIR

— Saturated or non-saturated modes

— Programmable rounding (convergent; two’s complement; truncated)

— Pre-fill mode to pre-condition the filter before the sample window opens

•

Full duplex synchronous serial interface to an external device

— Free-running clock for use by an external device

— Supports a 26-bit message length

•

Six priority-based queues per ADC

•

Trigger sources include software, timer channels and input pins

•

eTPU result interface

— Allows any ADC result to be exported to eTPU for use with reaction channels

•

Support for an additional 64–8=56 channels via external multiplexing
