MAX36025
DeepCover Security Manager for Tamper-Reactive
Cryptographic-Node Control with AES Encryption
General Description
Features
DeepCover™ embedded security solutions cloak sensitive
data under multiple layers of advanced physical security
to provide the most secure key storage possible.
S Cryptographic
Triple Mode Encryption: AES-ECB, AES-CTR, AES-CBC
Dual Encryption Cores to Allow Dual Key Cipher
Translation and Routing
On-Chip Secure Key Storage
Pipelined Dual Asynchronous Bidirectional SPI
Data Ports
The DeepCover Security Manager (MAX36025) is a
highly integrated device intended to address the security
requirements of high-end cryptographic systems and
data-at-rest storage applications. The device employs
a tamper-reactive dual AES cryptographic engine archi-
tecture that facilitates the cost effective implementation
of multiple cipher channels across compartmentalized
system nodes and storage elements.
S Storage
1K x 8 On-Chip Nonimprinting Memory with
High-Speed Tamper-Reactive Erase
External Serial Flash Interface
Tamper-Reactive NV SRAM Controller
Two SPI interfaces and one generic Serial Flash interface
are provided for secure, flexible communication to exter-
nal system nodes. The MAX36025 can be programmed
to route any of these interface inputs through one, both,
or neither of the dual AES engines, and also to any of
these interface outputs.

through an I C-compatible interface. The I C interface
can be secured using an integrated authentication proto-

decisions. Additionally, the MAX36025 can encrypt I C
communications using a configurable AES key.
The MAX36025 includes on-chip nonimprinting memory
that incorporates a high-speed, direct-wired clearing
function. The memory is constantly complemented in the
background to prevent memory imprinting of data. The
MAX36025 architecture allows the user to clear selec-
tive banks of the memory based upon specified tamper
events. In the event of a qualified tamper, the desired
bank(s) of memory are rapidly cleared and a negative
bias can be applied to erase external memory.

Crystal Oscillator Tamper Monitoring
S Differential Power Analysis and TEMPEST
Countermeasures
On-Chip Spread-Spectrum Clock Source for the
AES Cores and the External Memory Interface
Power Controller Ensures Constant Current
During Cryptographic Operations
The MAX36025 includes a seconds counter, watchdog
timer, CPU supervisor, nonvolatile (NV) SRAM control-
ler, and on-chip temperature sensor. In the event of a
primary power failure, an external battery source is auto-
matically switched in to keep the memory, time, and tam-
per-detection circuitry active. The MAX36025 provides
low-leakage, tamper-detection inputs for interfacing to
external sensors, interlocks, and antitamper meshes.
The MAX36025 also invokes a tamper event on absolute
temperature, if the temperature exceeds programmed
limits, or if the crystal oscillator frequency falls outside
of a specified window. The tamper event is latched and
time-stamped for fault recovery purposes.
