DESCRIPTION
The DS2251T 128k soft microcontroller module is an 8051-compatible microcontroller module based on
nonvolatile RAM technology. It is designed for systems that need large quantities of nonvolatile memory.
Like other members of the secure microcontroller family, it provides full compatibility with the 8051
instruction set, timers, serial port, and parallel I/O ports. By using NV RAM instead of ROM, the user can
program, then reprogram the microcontroller while in-system. The application software can even change
its own operation. This allows frequent software upgrades, adaptive programs, customized systems, etc.
In addition, by using NV RAM, the DS2251T is ideal for data logging applications. The powerful real-
time clock includes interrupts for time stamp and date. It keeps time to one-hundredth of seconds using its
on-board 32kHz crystal.
