Digital I/O:

• 48 Diode protected I/O lines

• 24 mA source and sink current

• Compatible with DMR and DOP expansion boards

• Deep FIFOs with DMA

• Two 2M-Word FIFOs

• Each FIFO is attached to a separate DMA channel

• 25 MHz bursted throughput

• 12.5 MHZ continuous throughput

• FIFO can be looped

Pulse Width Modulators:

• Eight PWM outputs

• Single-ended or Differential Outputs

• 16-bit resolution

• Separate period and width clocks provide full resolution at low duty cycles

• Optional Interrupt generations

Incremental Encoders:

• Four Incremental Encoder channels

• Single-ended or Pseudo-differential Inputs

• Variable frequency input filtering

• Max input speed of 40ns per transition

• 16-bit resolution

• Two channels can be combined for 32-bit resolution

• Connect to FIFO for position sampling

Advanced Interrupts:

• Two Advanced Interrupt Modules

• Interrupt on Match, Change, or Strobe

• All 48 bits are captured when the interrupt is generated

• Any combination of the 48 bits can be monitored

Programmable Clocks:

• Four programmable clocks

• Maximum frequency of 25 MHz

• Can be started and stopped by an interrupt or another clock

• Continuous or One-Shot Operation

• Can be cascaded

82C54 Timer/Counters:

• Six Timer/Counter Channels

• Fully programmable

• Input clock and gate driven from internal or external source

• 10 MHz maximum input
