The R-Engine86^(TM) (RE86) is a high performance, low cost, C/C++ programmable controller, and the first TERN controller based on the Am186ER CPU (40 MHz, 16-bit CPU, AMD). It is intended for industrial process control and high-speed data acquisition, and especially ideal for OEM applications.

The RE86 has 32KB internal RAM, which fulfills many embedded OEM product SRAM requirement. No external SRAM would be required for an OEM version of the RE86. This increase system reliability, decrease power consumption and cost.

The RE86 features fast execution times through 16-bit ACTF Flash (256 KW) and battery-backed SRAM (256 KW); it also includes 3 timers, PWMs, 32 PIOs, 24 PPIs, 512-byte serial EEPROM, an internal UART, a sync serial port, 3 timer/counters, and a watchdog timer. The three 16-bit timers can be used to count or time external events, up to 10 MHz, or to generate non-repetitive or variable-duty-cycle waveforms as PWM outputs. The 32 PIO pins from the Am186ER are multifunctional and user programmable.

A serial real timer clock (DS1337, Dallas) is a low power clock/calendar with two time-of-day alarms and a programmable square-wave output. A Dual UART (SCC2692 or SC26C92). provide two channels of full-duplex asynchronous receivers and transmitters; this combines with a single port available from the processor for a total of three RS-232 serial ports. (This differs from most other core Engine controllers, offering 2 ports through the processor.) The receivers are quadruple buffered to minimize the potential of receiver overrun or to reduce interrupt overhead. The UARTs incorporate 9-bit mode for multi-processor communications. Each UART also offer 7 TTL inputs and 8 TTL outputs. The PPI (82C55) provides an additional 24 user programmable bi-directional I/Os.

The 12-bit ADC (TLC2543) has 11 channels of analog inputs with single ended 0-5V input range, supporting a sample rate of up to 10 KH. The DAC (DAC7612) supports two channels of 12-bit, 0-4.095V analog voltage outputs capable of sinking or sourcing 5 mA. A high speed parallel ADC (AD7852, 300KHz, 8 ch., 12-bit, 0-5V), and a parallel DAC (DA7625, 5 ms, 4 ch, 12-bit, 0-2.5V) can be installed.

All chips are surface mounted for highest reliability.
