Measuring 4.8 by 3.4 inches, the TinyDrive is a C/C++ programmable industrial controller with a 16-bit CPU (NEC V25), up to 512 KB ROM/Flash, 512 KB battery-backed SRAM, a 512-byte EEPROM, a real-time clock (RTC72421), three serial ports, 16-bit timers, 42 I/O lines, power failure reset, watchdog, and 20 solenoid drivers.

At 24x2 screw terminals, the TinyDrive provides 22 resistor-protected inputs, including eight comparator inputs, 11 12-bit ADC, three interrupt inputs, as well as 20 solenoid driver outputs. Six solenoid outputs can be configured as inputs. These outputs are capable of sinking 350mA at 50V each channel and they can directly drive solenoids, relays, or lights.

The 12-bit ADC has a serial interface, successive-approximation, and sample-and-hold. The ADC features differential high-impedance reference inputs that facilitate ratiometric conversion, scaling, and isolation of analog circuitry from logic and supply noise, with low-error (*1LSB) over the full operating temperature range at 2500 Hz sample rate. It also features high-impedance reference inputs. The ADC input voltage range is 0V to 2.5V or 0V to 5V depending on reference voltage.

The eight comparator ADC inputs can be used to measure either digital or 0 to 5V analog inputs in 16 levels. The buffered digital inputs take +24V, +5V, or ground inputs. The optional 11 12-bit ADC features reference inputs (2.5V or 5V), a sample rate of up to 2.5 kHz, and a 0-5V input voltage range. A PAL (TDP100) can provide eight digital inputs, replacing the ADC.

Two RS-232 serial ports from the V25 supports up to 115,200 baud. The RS-485 port for the optional UART (SCC2691) supports normal 8-bit and 9-bit networking.  Three 16-bit timers provide precise timing. Two standby modes, HALT and STOP, can reduce power consumption.

An optional LCD interface can be installed, replacing the third optional UART SCC2691.

The optional 12-bit ADC has sample-and-hold, a high-impedance reference input, 11 single-ended 0-5V (or 0 to REF) inputs, and a 2.5 kHz sample rate.

The TinyDrive has a 5V linear regulator installed on-board (accepting input voltage of 9-12V)., and can be easily interfaced with most TERN controllers.
