The MAXQ1050 is a low-power secure microcontroller
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 sensors) 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 asynchronous receiver-transmitter) for
smart card communication. The device supports high-
speed encryption with hardware 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.
