TERN i386-Drive 32 bit CPU [intel i386EX][x86 compatible] 33MHZ C/C++ Programmable Controller, one 16bit ADC, one 24bit ADC, 22 ch. 12bit ADC, two 12bit DAC,Real Time Clock+Battery, 50+ I/O
The ID supports up to 512 KB 8-bit SRAM, 512 KB 8-bit Flash, 1 MB 16-bit SRAM, and 1 MB 16-bit Flash. A 512-byte serial EEPROM, which does not require a battery backup, can be used as an additional memory device to store important data. An optional real-time clock (RTC) provides information on the year, month, date, hour, minute, second, 1/64 second. A lithium coin battery can be installed to back up both the SRAM and RTC.
Two asynchronous serial ports from the i386EX support reliable DMA-driven serial communication at up to 115,200 baud with RS-232 drivers. The i386EX also offers one synchronous serial port. An optional UART SCC2691 and a dual UART SCC2692 can be added for an additional three asynchronous serial ports with RS-232 or RS-485 drivers.
Three PC-compatible 16-bit programmable timers/counters can generate interrupts or count external events, at a rate of up to 8 MHz, or can generate pulse outputs. Three 8-bit, multifunctional, user-programmable I/O ports are included in the i386EX. Four external interrupts are buffered by Schmitt-trigger inverters and provide active low inputs. A supervisor chip (LTC691) with a watchdog timer is on-board.
Two PPI chips (82C55) provide 48 user-programmable I/O lines totally free for application use. The optional SCC2692 UART provides 15 additional I/O lines.
The ID supports several optional ADC and DACs. Up to 22 channels of 12-bit ADC (LTC2543, 0-5V, 10 KHz), one 16-bit ADC (LTC1605, ±10V, 100 KHz), and one 24-bit ADC (LTC2400, 0-5V, 5 Hz) can be installed. Two 12-bit DACs (LTC1446, 0-4.095V, 10 KHz), one 100 KHz 12-bit DAC (LTC1450, 0-4.095V), and one 16-bit DAC (LTC1655, 0-4.095V, 10 KHz) are available.
Two quadrature decoders (HP2020) can interface to optical encoders for motion control. Schmitt-trigger inverters are provided. On-board expansion headers provide data lines, address lines, control signals, and pre-decoded chip select lines.
By default, a 5V switching regulator (up to 35V DC input) is installed to reduce power consumption and heat. The switching regulator introduces more noise than a linear regulator: a linear regulator can be installed upon request.
In "power-off" mode, the ID consumes very low (uA) power. Users can turn off the switching regulator via software, and use the RTC or an external signal to turn it on.
A MemCard can be installed on the ID to provide an additional 33 12-bit ADC, 6 24-bit ADC, 420 MB PCMCIA memory, and an Ethernet interface.Ordering Information (Qty 1/100/1K/5K+)
