program in a tiny package.
Micromint offers a variety of 8052-BASIC boards and other products. Both the BCC52 and
RTC52 are single-board systems that can also serve as the base of an expanded system. The
BCC52 uses edge connectors and a backplane, while the RTC52 is a stackable design. A
variety of expansion boards are available, including interfaces to displays, keypads, relays,
infrared control, and A/D converters. The BRUTE-52 is a single board with many expansion
options on-board.
Micromint’s Domino is a complete Basic-52 system in a 20-pin encapsulated package that’s
about the size and shape of a domino. It has a surface-mount 80C52-BASIC chip, 32
kilobytes each of RAM and EEPROM, and twelve I/O pins, two of which may be analog
inputs. The Domino’s BASIC-52 interpreter adds functions for measuring frequency and
period and for reading the analog inputs.
Prologic Designs offers an inexpensive bare pc board (Figure 15-2) and detailed manual for
8052-BASIC systems, for those who prefer building their own.
Blue Earth Research’s Micro-440e is a complete system on a tiny pc board, just 1.9" x 2.25"
(Figure 15-3). The system uses a surface-mount 83C51FB chip with both Blue Earth’s
version of BASIC-52 and a monitor program in ROM. A case and expansion boards are also
available. The Micro-485 adds an analog-to-digital converter, clock and calendar, and an
RS-485 interface for networking.
