The R-51SP is
small (1.2" x 2.25") two-layer board designed for embedded
applications using an 8051 in the single-chip mode.
built and tested
The R-51SP is
low cost and flexible, making it ideal as an embedded controller. The
R-51SP has 32 I/O lines and one or two serial
ports, (two when used with the DS87C520/DS89C420.) The board can be used with a wide variety of
preprogrammed 8x5x processors in the 44 pin PLCC package. These include chips
by Intel, Philips, Infineon, Atmel, SST, and ISSI. (For
40 pin dip chips see our R-51SD.)
This board use preprogrammed processors. You can not program the chips
on this board. For a programmer see our board the R-51PB.
Our Reads51 software has been completely updated to
support this board.
Reads51 is an integrated applications software development system, which runs
on an IBM PC or compatible host. Reads51 allows writing, compiling,
assembling, debugging, downloading, and running applications software in the
MCS-51 language. Reads51 contains a C compiler, relative assembler,
linker/locator, editor, chip simulator, assembly language debugger, and
host-to-board communications in a user-friendly, menu-driven environment.
