version of the 5E called the 586-Engine-P (5P) is now available. The
5P integrates a variety of features that makes it a more powerful,
stand-alone product. It has its own onboard RS232 drivers and
voltage regulators, allowing it to be deployed totally independent
of any motherboard support. The 5P also features a new, ultra-high
speed 4 ch. 1 MHz 16-bit ADC.
The FPU provides arithmetic instructions to handle numeric data and
transcendental functions for sine, tangent, logarithms, etc, making
this controller useful for intensive computational applications. It
is estimated to be 10-50 times faster than software-emulate on an
8/16-bit controller without a FPU.
The 586-Engine supports up to 15 external interrupts. There are a
total of seven timers, including one programmable interval timer
(PIT) that provides three 16-bit PIT timers and three 16-bit GP
timers, plus a software timer. These timers can support timing or
counting external events. The software timer provides a very
efficient hardware time base with microsecond resolution. A
real-time clock (RTC) provides time-of-day, 100-year calendar and
114 bytes of battery backed RAM.
Two industrial-standard 16550-compatible UARTs support baud rates up
to 1.152 M baud. One synchronous serial interface (SSI) supports
full-duplex bi-directional communication. One additional optional
UART (SCC2691) can be installed.
The 586-Engine? boots from on-board 256K 16-bit ACTF Flash, and
supports up to 256K 16-bit battery-backed SRAM. SDRAM and DMA are
not supported. Up to 1GB memory expansion can be added with
MemCard-A and PCMCIA ATA Flash cards.
|There are 32 programmable multifunctional
I/O lines (PIO) that can be used as general I/O or other
functions. Two supervisor chips monitor 5V and 3.3V and provide
power failure detection, watchdog and system reset. The 2.5V is
used for the SC520 core and 3.3V for the I/O operation. Signal
lines on headers are 3.3V output, and 5V maximum input. All
components are soldered on board for highest reliability.
The 586-Engine? can be powered with a single regulated 5V
with the on-board 3.3V and 2.5V regulators. It also can be
powered by external regulated 5V, 3.3V, and 2.5V. A total of 19
analog inputs are supported with a serial ADC (TLC2543, 11
inputs, 20KHz sample rate, 12-bit, 0-REF+) and a parallel ADC
(AD7852, 8 inputs, 100KHz sample rate, 12-bit, 0-5V). Two serial
DACs (LTC1446, 2 channels, 0-4.095V) and a parallel 12-bit DAC
(DA7625, 4 channels, 0-2.5V) can be in-stalled to provide a
total of 8 analog outputs.
The 586-Engine shares a similar pin-out and physical
dimensions with the R-Engine, i386-Engine, A-Engine, and a
number of other similar 'Engine' boards.. As compared to these
other engine-based controllers, the 5E offers substantially more
computing power at greater per-unit costs and power
requirements. The 388 pin BGA package of the SC520 CPU makes
repair support for the 586-Engine not available.
