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

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.

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.
