The R-51SD 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 boards (top and bottom)
The R-51SD is
and flexible, making it ideal as an embedded controller. The R-51SD 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 40 pin dip package. These include chips
by Intel, Philips, Infineon, Atmel, SST, and ISSI. (For
44 pin PLCC chips see our R-51SP.)
The R-51SD is populated with parts on both the top and bottom of board
allowing for it's extremely small footprint.
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
