The DS5230 is a highly secure, four clocks-per-
machine cycle, 100% 8051-instruction-set-compatible
microprocessor in the secure microcontroller family
from Maxim Integrated Products. It is a feature-reduced
and cost-reduced version of the popular DS5250 high-
speed secure microcontroller. Its proven architecture
protects embedded application software and data
against reverse engineering or cloning. A key feature of
the device is that it encrypts its program memory with a
hardware-based single- or triple-DES (data encryption
standard) algorithm and provides optional data memory
encryption, making it almost impossible to extract infor-
mation. It also implements block cipher encoding that
uses block addresses to modify the encrypted data,
further strengthening security. This makes the device
ideal for storage and transmission of passwords, per-
sonal identification numbers, encryption keys, and
other highly confidential information.
+ Denotes a lead-free/RoHS-compliant package.
