Products with an 8051 core processor.
RTC31/52
The RTC31/52 is our all-time best price-performer. The RTC31 is a 3.5" x 3.5" real-time controller that uses an 8031 processor and is intended for OEM assembly-language applications. The RTC52 uses the same PC board but has a Micromint 80C52-BASIC processor instead of an 8031. With BASIC, the RTC52 is software compatible with our BCC52 series, as well as allowing for onboard program development using a common RS-232 terminal. The 80C52-BASIC processor can also be jumper-selected to function as an 80C31/80C32 processor.
The RTC31/52 was designed to provide a minimal configuration for cost-conscious applications. It can be greatly expanded to perform more extensive control and data-acquisition tasks while maintaining the same small 3.5" x 3.5" footprint by using a stacked-board expansion system. Additional analog and digital I/O boards are piggybacked on top of the processor board and secured with stand-offs.
RTC-320/52Plus
One of Micromint's hottest-selling products for the past five years has been the RTC31/52 stackable controller. It has been a leading price/performance choice among our customers. With our new RTC320 and RTC52-Plus boards, we have expanded the value of that relationship even more.
Occupying the same small 3.5" x 3.5" RTC footprint and 5-V-only power, the RTC320 uses the new Dallas Semiconductor 80C320, which is 8031 code-compatible and 35 times faster. At 33 MHz, the RTC320 is an 8-MIPS controller! Along with the new powerful processor, the RTC320 board accommodates up to 192 KB of memory, 2 serial ports (RS-232 and RS-485), 24 bits of TTL parallel I/O, and a 2-channel 12-bit ADC. The RTC320 puts some real firepower under the abundant variety of RTC I/O expansion boards. Plugging in your favorite ICE or EPROM emulator is the easiest way to develop code. For the diehards who like to twiddle the bits directly, we have a ROM monitor specifically designed for the Dallas '320.
Domino
The mighty Domino packs an 80C52 processor with a full floating-point BASIC, 32-KB SRAM, 32-KB EEPROM, 12 parallel I/O bits, and a 2-channel 12-bit ADC in a 0.8-cubic-inch encapsulated package that consumes only 75 mW.
Domino is fully RS-232A, RS-422, and RS-485 compatible without extra components. Besides the two interrupts and three timers provided in the hardware, Domino is further enhanced by firmware which delivers an I2C bus, two PWM outputs, and direct period and frequency measurement.

BCC52
The BCC52 computer/controller is one of our hottest selling stand-alone single-board microcomputers. Its cost-effective architecture needs only a power supply and terminal to become a complete development or end-use system. Programmable in BASIC or machine language, the BCC52 uses Micromint’s 80C52-BASIC CMOS microprocessor, which contains a ROM-resident, 8-KB, floating-point, BASIC-52 interpreter.
The BCC52 contains sockets for up to 48 KB of RAM/EPROM, an "intelligent" 2764/128 EPROM programmer, three parallel ports, a serial terminal port with auto baud rate selection, a serial printer port, and is bus compatible with the full line of BCC-bus expansion boards. The BCC52 bridges the gap between expensive programmable controllers and hard-to-justify, price-sensitive control applications. BASIC-52’s full floating-point BASIC is fast and efficient enough for the most complicated tasks, while its cost-effective design allows it to be considered for many new areas of implementation. It can be used both for development and end-use applications.
BCC52CX
Our all-CMOS eXpanded BASIC-52 computer/controller is a stand-alone single-board microcomputer that measures 4.5" x 6.5" and takes the best features of our original BCC52 and adds attributes like RS-485 communication, more memory, and total CMOS operation in the same-size package. Like the BCC52, the BCC52CX uses Micromint’s 80C52-BASIC 8-bit CMOS microprocessor. It needs only a power supply and terminal to become a complete system a power supply and terminal to become a complete system programmable in BASIC or machine language.
Allowing use of 32K x 8-bit memory chips, the BCC52CX has sockets for 64 KB of RAM and 64 KB of EPROM. An onboard "intelligent" 27C256 programmer uses standard and fast programming algorithms. Console serial support can be directed to RS-232 or RS-485 drivers. An auxiliary RS-232 serial output port supports serial printer output, and three 8-bit TTL bidirectional parallel ports are available through an on-board PPI. The BCC52CX is Micromint BCC-bus-compatible, allowing all of the BCC-bus peripheral boards to be used with BCC52CX.
