Description
The DS5001FP 128k soft microprocessor chip is an 8051-compatible microprocessor based on NV RAM technology and designed for systems that need large quantities of nonvolatile memory.
It provides full compatibility with the 8051 instruction set, timers, serial port, and parallel I/O ports.
Features
- 8051-Compatible Microprocessor Adapts to Its Task - Accesses up to 128kB of nonvolatile SRAM - In-system programming through on-chip serial port - Can modify its own program or data memory - Accesses memory on a separate byte-wide bus - Performs CRC-16 check of NV RAM memory - Decodes memory and peripheral chip enables.
- High-Reliability Operation.
- Maintains all nonvolatile resources for over 10 years.
- Power-fail reset.
- Early warning power-fail interrupt.
