    SC52

    8052-single board target and development system

    The SC52 is based around Intel's advanced 8052 microprocessor with on-chip BASIC. It can be programmed in BASIC or assembly language and programs can be stored in EPROM to create systems which autostart from powerup. The 8052 has many exciting features which include full floating-point on-chip BASIC interpreter, 3 counter-timers, full duplex UART, 256 bytes on-chip RAM, 96K addressing range and 6 interrupts.

    The on-chip 8052AH BASIC is designed for process control. It is easy to use - entering a program into RAM, debugging, testing and programming it into EPROM need only take a few minutes. The BASIC has a number of features which make controlling hardware simple, including interrupt handlers in BASIC, on-chip real time clock, BCD floating point, hexadecimal arithmetic, logic operators, auto start on power-up, EPROM programming routines, memory and register settings and multiple program files in memory.

    One feature especially useful in control systems is that interrupts can be handled in BASIC. This includes interrupts from external sources and from the internal real-time clock.

    Developing programs on the SC52 is very easy. You can enter and edit BASIC programs using the on-board RAM. When the programs are fully tested and debugged, on-board EPROM programming hardware and software transfers then to EPROM, to create a standalone autostart system, all on one board!
