Product short description:
- 64 TTL bi-directional I/O
- Four 16-bit counter/timer channels with six operating modes
- Change of state and level interrupts
Consult factory for long-term availability.
The PMC464 module provides 64 digital input/ output channels and four 16-bit multifunction counter/timers.
Sixteen digital I/O channels can be programmed as an input or an output on an individual channel basis. The other 48 digital input/output channels are programmed as inputs or outputs on an 8-bit port basis. All inputs support change of state and high/low level transition interrupts.
Four 16-bit multifunction counters/timers can be configured for pulse width modulated output, watchdog timer, event counter, frequency measurement, pulse width measurement, period measurement, or one shot pulse output. The four 16-bit counters can also be configured into two 32-bit counter/timers. A conduction-cooled version is also available.
Specifications
Digital I/O
I/O channel configuration: 64 bidirectional TTL transceivers.
Channels 0-47: Direction controlled on a port basis.
Channels 48-63: Direction controlled independently (shared as counter/timer control signals). (48-62 for 464R)
Reset/power-up condition: All channels default to input.
Digital Input
Input voltage range: 0 to 5V DC.
Input signal threshold (channels 0-47): Low to high: 2.0V typical. High to low: 0.8V typical.
Input signal threshold (channels 48-63): Low to high: 3.5V typical. High to low: 1.5V typical.
Input response time: 10 nanoseconds, typical.
Interrupts: 64 channels of interrupts for high-to-low, low-to-high, or any change-of-state event types.
Debounce: Selectable for each channel. User-selectable (5.6μS, 50.4μS, 408.8μS, or 3.276mS).
Digital Output
Output voltage range: 0 to 5V DC.
Output ON current range (channels 0-47): -15 to 64mA.
Output ON current range (channels 48-63): -32 to 32mA.

Turn on time: 10nS.
Turn off time: 10nS.
Counter/Timers
Counter/timer configuration: Four 16-bit counters can be configured into two 32-bit counters.
Functions: Pulse width modulation, watchdog timer, event counting, frequency measurement, period measurement, pulse width measurement, and one-shot/repetitive.
Counter input: Each counter has an INA, INB, and INC input port. These TTL input signals control start/stop, reload, event input, external clock, trigger, and up/down operations.
Counter output: Each counter has one output signal. The TTL output is used for waveform output, watchdog active indicator, or 1.6μS pulse upon counter function completion. Programmable as active high or low.
Clock frequencies: Selectable for 20MHz, 10MHz, 5MHz, 2.5MHz, 1.25MHz or external up to 8MHz.
Minimum I/P event: 100nS (debounce disabled).
Minimum pulse measurement: 100nS (debounce disabled).
Minimum period measurement: 200nS (debounce disabled).
Minimum gate/trigger pulse: 100nS (debounce disabled).
Board crystal oscillator: 20MHz.
PMC Compliance
Conforms to PCI Local Bus Specification, Revision 2.2 and CMC/PMC Specification, P1386.1.
4K Memory Space Required: One Base Address Register.
Signaling: 5V Compliant, 3.3V Tolerant.
Environmental
Operating temperature: 0 to 70°C (PMC464 / R) or -40 to 85°C (PMC464E / CC)
Storage temperature: -55 to 105°C.
Relative humidity: 5 to 95% non-condensing.
MTBF: 1,750,590 hrs. at 25°C, MIL-HDBK-217F, notice 2.
Power: 160mA at +5V, typical.
