Flexible Input Deterministic Output (fido ® )
32-Bit Real-Time Communications Controller
The UIC is a very flexible hardware solution designed to support numerous interface
requirements. When working in concert with the on-board Peripheral Management Unit (PMU)
and on-board data buffers, the operation of the interfaces requires little core processor
intervention. This allows the processor to use its bus bandwidth for more important functions
than managing data traffic. The UIC design can support complex protocols such as Ethernet or
GPIO functions.
2.6
The fido1100 incorporates the following set of internal peripherals:
2.6.1 Timer Counter Units (TCU)
Four software-configurable UICs
Each supports 10/100 Ethernet, CAN, UART, SPI, I
Software libraries are provided for various interface protocols and formats
User-programmable integrated 256-location MAC address filter
Dedicated PMU offloads main CPU bus traffic
Large 1K
At a minimum, each UIC can support 1 Ethernet port (MII), 2 UARTs, or 18 GPIO
CPU DMA—Two independent channels of DMA for data transfer
Internal Peripherals
Two Timer Counter Units (TCU)—The fido1100 is equipped with two Timer Counter
Units.
– Four channels per timer; any channel can be either input capture or output compare.
– Input captures can be either rising or falling edge.
– External signal clocking can be rising edge, falling edge, or both edges of input
– Output compare can be assert high, assert low, or toggle mode.
– Underflow, overflow, input-capture, or output-compare conditions can trigger an
– Timers can be programmed for auto-stop or auto-reload.
– Timer can generate an internal interrupt to wake up the processor from sleep mode.
– Timer periods in excess of 50 seconds are achievable.
