Small Controller Includes BASIC

A small, low-power controller with analog, digital, and serial I/O is available from Remote Processing. The RPC-210 uses Analog Devicesý new ADUC-812 CPU operating at 11.06 MHz to provide a fully integrated 12-bit data acquisition system. The controller includes a BASIC language for on-board programming and is useful in remote or mobile data logging and light control situations. The RPC-210 board measures 2.80” ý 6.20”.

A significant number of analog I/O, digital I/O, and counter lines are available. Analog I/O consists of an 8-channel, 12-bit A/D converter and a two-channel analog output. Two 12-bit D/A converters provide 0.1- to 5-V or 0.1- to 2.5-V outputs. Twenty-four digital I/O lines drive optomodules and reed switches. Two RS-232 serial ports are available, one is convertible to RS-232/485. Pulse counting, quadrature encoder inputs, pulse width or frequency measurements are possible using the 20 MHz hardware counter. SPI lines and an expansion port are also included. An LCD display and keypad port provide an operator interface.

A real-time clock wakes up the card from low power mode and provides power to external devices at a programmed time. A battery backs up the clock and 512-KB RAM in power off or stand-by mode.

A 512-KB flash EPROM stores programs and data. Remote communication is possible using modems or laptop PCs. Power inputs are 5 V or 5.4 to 16 V. Regulated 5 V is available for external circuits. Power requirements are only 20 ýA in standby mode.

The board is usually programmed in RPBASIC-52, a set of Intel BASIC-52, but is programmable in C and assembly. Program development uses a PC with a serial port connected to the RPC-210, and program changes can be made on the board. An event driven, multitasking BASIC is included, and all hardware is supported through the BASIC. Development systems are available.

The RPC-210 sells for $275.
