CompactPCI Boards CompactPCI Boards NEW! AcPC464 Digital I/O and Counter/Timers The AcPC464 module provides 64 digital input/ output channels and four 16-bit multifunction counter/timers. All 64 I/O channels, when set as inputs, support config- uration for interrupts on either a change-of-state or on This module saves money and CompactPCI slots by combining digital I/O and counter/timer functions on a single card. a high-to-low or low-to-high transition. A debounce timer is selectable to help filter out false transitions. Counter clock frequencies: Selectable for 20MHz, Specifications 10MHz, 5MHz, 2.5MHz, 1.25MHz or external up to Four 16-bit multifunction counters/timers are config- Digital I/O 8MHz. urable for pulse width modulated output, watchdog I/O channel configuration: Minimum I/P event: 100nS (debounce disabled). timer, event counter, frequency measurement, pulse 64 bidirectional TTL transceivers. Minimum pulse measurement: 100nS (debounce disabled). width measurement, period measurement, or one shot Channels 0-47: Direction controlled on a port basis. Minimum period measurement: 200nS (debounce disabled). Channels 48-63: Direction controlled independently pulse output. The four 16-bit counters can also be (shared as counter/timer control signals). Minimum gate/trigger pulse: 100nS (debounce disabled). configured into two 32-bit counter/timers. Reset/power-up condition: All channels default to input. CompactPCI bus Compliance Digital Input Features Meets PCI spec. V2.2 and PICMG 2.0, R3.0. Input voltage range: 0 to 5V DC. Data transfer bus: Slave with 32-bit, 16-bit, and 8-bit data Digital I/O Input signal threshold (channels 0-47): transfer operation. ■ 64 digital input/output channels: Low to high: 2.0V typical. Interrupts (INTA#): Interrupts requested on Interrupt A. - 16 individually programmable channels High to low: 0.8V typical. Plug-and-Play: The system maps the base address into the - 48 channels configured on an 8-bit port basis Input signal threshold (channels 48-63): PCI bus 32-bit memory space. Low to high: 3.5V typical. ■ Programmable change of state/level interrupts High to low: 1.5V typical. Environmental ■ Input signal filtering debounce logic Operating temperature: 0 to 70°C (AcPC464) or Interrupts: 64 channels of interrupts for high-to-low, -40 to 85°C (AcPC464E) low-to-high, or any change-of-state event types. Counter/Timer Storage temperature: -55 to 125°C. Debounce: Selectable for each channel. User-selectable ■ Four 16-bit or two 32-bit counter/timer channels (5.6µS, 50.4µS, 408.8µS, or 3.276mS). Relative humidity: 5 to 95% non-condensing. (control lines shared with 16 TTL I/O channels) Digital Output MTBF: Consult factory. Output voltage range: 0 to 5V DC. Power: 160mA at +5V, typical. ■ Six operating modes: Output ON current range (channels 0-47): -15 to 64mA. - Pulse width modulation Ordering Information Output ON current range (channels 48-63): - Watchdog timer -32 to 32mA. - Event counter CompactPCI Boards Output pullups: 4.7K ohm socketed resistors. - Frequency measurement AcPC464: Digital I/O and counter/timer module - Pulse width or period measurement AcPC464E: Same as AcPC464 plus extended temp.range Counter/Timers - One-shot and repetitive one-shot Counter/timer configuration: Four 16-bit counters can be Software (see Page 81) configured into two 32-bit counters. ® ■ TTL-compatible thresholds PMCSW-API-VXW: VxWorks software support package Functions: Pulse width modulation, watchdog timer, event ® PCISW-API-QNX: QNX software support package ■ Power-up and system reset is failsafe counting, frequency measurement, period measurement, ® pulse width measurement, and one-shot/repetitive.
