Parallax P2 Edge Module - Datasheet

● Programmable 32-bit clock output, transition output, NCO/duty output

● Triangle/sawtooth/SMPS PWM output, 16-bit frame with 16-bit prescaler

● Quadrature decoding with 32-bit counter, both position and velocity modes

● 16 different 32-bit measurements involving one or two signals

● USB full-speed and low-speed (via odd/even pin pairs)

● Synchronous serial transmit and receive, 1 to 32 bits, up to clock/2 baud rate

● Asynchronous serial transmit and receive, 1 to 32 bits, up to clock/3 baud rate

Six clock modes, all under software control with glitch-free switching between sources:

● Internal 20M Hz+ RC oscillator, nominally 25 MHz, used as initial clock source

● Crystal oscillator with internal loading caps for 7.5 pF/15 pF crystals, can feed PLL

● Clock input, can feed PLL

● Fractional PLL with 1..64 crystal divider --> 1..1024 VCO multiplier --> optional (1..15)*2 VCO post-divider

● Internal ~20 kHz RC oscillator for low-power operation (130 µA)

● Clock can be stopped for lowest power until reset (100 µA, due to leakage)

Power requirements:

● Core: 1.8 VDC, powered via VDD pins

● Smart I/O pins: 3.3 VDC, powered in groups of 4 via VIO pins

Physical characteristics:

● Package type: Exposed-pad TQFP-100

● Dimensions: 14 x 14 mm

● Operating temperature range: AEC-Q100 Level 2 (-40 to +221 °F, -40 to +105 °C)

● Moisture Sensitivity Level (MSL) 3 (168 hours)
