MPC184VFB

Specialized ICS Overview

The MPC184VFB is a security processor from the S1 family, designed to offload computationally intensive cryptographic functions. It features dedicated execution units for RSA/ECC, DES/3DES, AES, ARC Four, and message digests (SHA-1/256, MD5). The device supports 8xx or PCI bus interfaces operating up to 66 MHz with 32-bit address/data buses. Powered by a 1.5V core and 3.3V I/O, it dissipates approximately 1.0W. Encased in a 252-pin MAPBGA package measuring 21x21 mm, it includes 8KB of internal scratchpad memory for key and context storage.

Specialized ICS Procurement Notes

Verify the specific suffix 'VFB' against official documentation to confirm package type and temperature range. Ensure compatibility with host systems using 8xx or PCI bus protocols. Confirm that the 1.5V core voltage requirement aligns with system power design constraints.

Specialized ICS Selection Notes

Select this component when hardware acceleration for asymmetric and symmetric cryptography is required to reduce host CPU load. Suitable for systems needing support for Elliptic Curve Cryptography alongside standard block ciphers. Consider the 252-MAPBGA footprint and 1.0W power dissipation during thermal management planning.

Specialized ICS Part Context

The MPC184 belongs to the S1 family of security processors developed for commercial networking applications. It derives technology from government-grade security solutions and utilizes fifth-generation execution units proven in related models like the MPC180 and MPC190.

Specialized ICS FAQ

What public key algorithms does the MPC184 support?

The Public Key Execution Unit (PKEU) supports RSA, Diffie-Hellman, and Elliptic Curve Cryptography (ECC) in both F(2)m and F(p) modes.

How does the MPC184 handle data movement?

It acts as a bus master on the 8xx or PCI bus, allowing it to directly read descriptors and write results to system memory, thereby offloading data movement from the host processor.

What is the purpose of the 8KB gpRAM?

The 8KB general-purpose RAM serves as scratchpad memory for storing keys, initialization vectors (IVs), and context to minimize setup time and improve performance for small packets.
