DM7820HR High speed Digital I/O dataModule® February 1, 2015 RTD Embedded TechnologiesInc — No Comments The DM7820 provides 48 bits of high speed digital I/O. It interfaces with the 33MHz PCI bus and uses large FIFOs and DMA transfers to allow for efficient management of digital data. Several peripherals, such as Pulse Width Modulators, Incremental Encoders, Programmable Clocks, 82C54 Timer/Counters and Advanced Interrupt Modules are all on board. All 48 bits have an individually programmed direction and mask. The Advanced Interrupt Modules provide Match, Event, and Strobe interrupts which latch all 48 bits upon firing. Peripherals can be connected internally and a large selection of interrupts can be generated. This wide variety of configuration options allows for the realization of many complex digital I/O scenarios. 48 Diode-protected digital I/O33MHz, 32-bit PCI-bus interfaceTwo 2M-Word FIFO buffers25MHz uni-directional or 12.5MHz bi-directional throughput8 PWM outputs with 16-bit resolutionIndividual period and width clocks for PWM customization4 incremental encoders with 16-bit resolution6 programmable clocks6 82C54 timer/counters2 Advanced Interrupt Modules provide Match, Event, and Strobe interruptsHigh level of customization via a multitude of interrupt and clock sourcesEach bit has a separate direction and maskOptional rugged IDAN® enclosure system About RTD Embedded TechnologiesInc RTD is a founder of the PC/104 Consortium and an ISO 9001 and AS9100 certified company.
