TERN MiniDrive 16bit CPU(NEC V25)[x86 compatible] 8MHZ C/C++ Programmable Controller, 24 I/O w/ multiplexed functions, 8 comparator/4bit ADC, 3 interrupt inputs, 2 RS232, 7 solenoid drivers, LCD interface
As of 2003, this product is being discontinued as NEC has ended production on the NEC-V25. Limited inventories for prior customers available..
Two high speed, full-duplex RS-232 serial ports support 115,200 baud or higher. Five LCD headers on-board support 16x2, 20x4, 40x4 character type LCDs, and 128x128, 240x64, 240x128 dot graphic LCDs. A beeper and a keypad can be installed.
The MiniDrive can be directly solder-attached on the back of an LCD module. An optional switching regulator (MAX766) can be installed to provide -15V for graphic LCDs. The MD provides all these signals on five headers with various pin out configurations in order to match various LCD modules as shown below.
Eight comparator inputs can be used as digital inputs or measuring analog inputs in 16 levels. Three external interrupt inputs can trigger the immediate execution of user programmable interrupt service routines.
The MiniDrive is C/C++ programmable with a 16-bit CPU (V25, 8MHz). It supports up to 512KB EPROM/Flash in a 32 pin ROM socket and up to 512KB battery-backed SRAM in a 32 pin RAM socket. The 24 I/O from the CPU lines are multiplexed with control and I/O functions.
It also features three 16-bit timers and two high speed counters (up to 500 kHz). It is also equipped with power failure detection, watchdog timer, LED, +5V, -12V/-15V power supplies. Two standby modes, HALT and STOP, can reduce the system total power consumption.
The MiniDrive88, despite its name, is significantly different from this MiniDrive. It is intended for use as a control unit with on-board microprocessor, and has up-to 35 solenoid drivers.
