MB91403's Support for IPv6 and Security Features Enables Ubiquitous Computing
EMBEDDED SYSTEMS CONFERENCE, SAN FRANCISCO, March 7 /PRNewswire/ --
Fujitsu Microelectronics America, Inc. (FMA) today introduced a new family of
microcontrollers developed for network-enabled household appliances, including
the industry's first 32-bit MCUs that incorporate a full range of networking
security features, on-board ROM and RAM, and support for IPv6, the next-
generation Internet protocol.
The MB9140x series from Fujitsu features the MB91403, which supports IPv6
and includes encryption circuitry supporting the Advanced Data Encryption
Standard (AES), Data Encryption Standard (DES), 3DES, and other established
cryptographic systems. The encryption circuits in the MB91403 are 150 to 200
times faster than software-based encryption, and are complemented by
authentication circuitry. The series also supports the MD5 and SHAR1
authentication standards, key exchange methods DH 1/DH 2, and the Internet Key
Exchange (IKE) protocol with hardware engine.
The series also includes the MB91401, a 32-bit network system MCU that
supports IPv6, and the MB91402, which is available for customers whose designs
do not require security features. All the new MCUs can operate as standalone
systems or as companion chips for existing designs.
Each of the new system-on-chip MCUs is designed to simplify development of
IPv6-capable products for ubiquitous-computing environments. On-board, high-
capacity ROM and RAM reduce the need to add external memory, enabling lower
overall system costs with fast, up-to-date, security-support features for
embedded applications. Each device incorporates all the basic functions needed
to serve as a controller for an appliance, including a 32-bit RISC CPU, an FR
core, timer, interrupt controller and UART.
"This impressive 32-bit MCU family delivers the processing power,
performance and security features required for Internet age appliances, and
for important emerging applications that must include the best available
encryption capability," said Akio Nezu, senior marketing manager for the
Embedded Products group at Fujitsu Microelectronics America. "As we move into
the era of ubiquitous computing, users will be able to connect portable and
handheld devices to the Internet with full confidence in reliability, privacy
and security, because of the performance of this new generation of
microcontroller technology."
High-capacity Embedded RAM and ROM
The MB9140x family incorporates 8 KB of high-speed data RAM, 4 KB
instruction cache, along with 256 KB ROM and 64 KB RAM, which reduce the need
for external memory chips, resulting in lower costs and more compact circuit
boards. If more RAM is needed, SDRAMs can be added externally in applications
where the device can serve as a buffer for a high-data-traffic application, or
to cache data that is transmitted over the network.
MB91403's Support for IPv6 and Security
The MB91403 supports IPv6 over Ethernet running at either 10 Mbps or 100
Mbps, enabling Internet-capable appliances to connect to the network using
individual IP addresses. The chip's hardware-based layer-filtering
functionality will admit only the appropriate packets, so the communication
process runs effectively via an appliance's CPU. The MB91403 also supports
IPv4.
The full range of security technology incorporated in the MB91403 ensures
that Internet-enabled appliances are fully secured. The encryption circuitry
is complemented by authentication circuitry. Customers can easily develop
their own applications with industry-standard authentication support.
Pricing and Availability
The MB91401, MB91402 and MB91403 are manufactured using Fujitsu's 0.18-
micron CMOS process, and packaged in 144-pin LQFPs. Pricing for the MB91401
begins at $15.78, for the MB91402 at $9.92, and for the MB91403 at $12.86 each
in 1,000-unit quantities.
