Maxim DS5002FP Secure Microprocessor
The DS5002FP is a secure version of the DS5001FP 128 kB soft microprocessor, adding advanced security mechanisms that resist observation, analysis, and physical attacks. It supports 32 kB, 64 kB or 128 kB of non‑volatile SRAM, in‑system programming, encrypted memory, a true‑random key generator, and optional self‑destruct input.
Key specifications include a wide operating temperature range, multiple voltage options, low‑power modes, and built‑in power‑fail monitoring that switches to a lithium backup cell. The document provides detailed electrical characteristics, timing diagrams, pin‑out information, and ordering data for various package options.
| Operating Temperature Range | -40 °C to +85 °C |
|---|
The device operates from –40 °C up to +85 °C.
It monitors VCC and provides a power‑fail reset, an early‑warning interrupt, and automatically switches to a lithium backup cell when VCC falls below the VLI threshold.
