MAXQ1050
DeepCover Secure Microcontroller
with USB and Hardware Cryptography
General Description
Features
DeepCover™ embedded security solutions cloak sensi-
tive data under multiple layers of advanced physical
security to provide the most secure key storage possible.
The DeepCover Secure Microcontroller (MAXQ1050)
was designed for USB secure token and smart card
reader applications that require certificate-based or
other public key cryptographic schemes. The device
also incorporates a sophisticated security mechanism
to protect secret key data; two self-destruct inputs and
environmental monitors (temperature and voltage sen-
sors) erase secret key data when an attack condition is
detected. The device has an integrated full-speed USB
device interface (including transceiver), hardware SPI
controller, and an ISO 7816 UART (universal asynchro-
nous receiver-transmitter) for smart card communication.
The device supports high-speed encryption with hard-
ware accelerators for AES, RSA, DSA, ECDSA, SHA-1,
SHA-224, SHA-256, DES, and 3DES. A true hardware
random-number generator is included for key generation
and challenge generation.
The device uses the 32-bit, pipelined, highly efficient
MAXQ30 microcontroller core. It integrates 128KB flash
memory, 12KB of volatile SRAM, 4KB of battery-backed
erasable NV SRAM, and 256B of battery-backed, secure
zeroization NV SRAM. An additional 1.5KB of volatile cryp-
tographic memory can also be used as general-purpose
data memory. The 256B of battery-backed NV SRAM can
be used for key storage and other critical data. The 256B
memory can be erased in less than 1Fs using a single
pulse (“rapid zeroization”), even in battery-backed mode.
The device is powered either from the USB bus or by a
separate 3.3V voltage supply. A battery connection is
provided for applications that want to maintain secret key
data for years without draining the battery from application
use. In battery-backed mode, the NV SRAM and security
sensors consume less than 240nA (typ). Battery backup is
optional; applications can choose to store critical data in
the flash memory when the cost of the battery outweighs
the benefits of constant monitoring for tamper conditions.
