Atmel Releases the First Secure Microcontroller With 256-Kbyte Flash Dedicated to the Smart Card Market.Business Editors/High-Tech Writers NANTES, France--(BUSINESS WIRE)--Oct. 3, 2000 Atmel Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ), released today the high performance secure microcontroller with the largest reprogrammable non-volatile memory Refers to memory chips that hold their content without power being applied. It may refer to chips that are not changeable, such as ROMs and PROMs, or to chips that can be rewritten many times such as flash memory. . The T89SC256C is an 8/16-bit secure microcontroller based on 80C251 enhanced architecture, software compatible with any existing 80C51-based application. Its outstanding on-chip compact Flash memory of 256 KBytes, together with its embedded fast Arithmetic Crypto Processor, and its efficient security features, give this product all the advantages needed to develop any application where security, fast computation, short time-to-market and low cost are required. Due to its small size (less than 25 mm(2)), and its very low power consumption (10 mA @5V-5mA @3V), the T89SC256C is naturally dedicated to embedded smart card applications. Its communication interfaces (UART (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice and SPI (1) (Stateful Packet Inspection) See stateful inspection. (2) (Service Provider Interface) The programming interface for developing Windows drivers under WOSA. ) also enable the cryptocontroller to support larger secure systems such as smart card readers and Set-Top-Boxes. The T89SC256C offers an original "Full Flash" architecture: a unique Flash memory space is provided to store data and programs. Thanks to the high integration 0.35 um CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. technology used to design the product, it has been possible to integrate by far the highest non-volatile memory size of the market: 256 Kbytes to date the largest embedded flash in secure microcontrollers has been 64 Kbytes. The Flash memory also offers real advantages of flexibility (fast prototyping and reduction of time-to-market), and security (versus other memory technologies like ROM). The large embedded working memory (RAM: 4.5 Kbytes) supports the use of modern programming languages. The 80C251 core is clocked by a high frequency tunable internal clock (up to 24 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. ), and offers software compatibility with any existing application developed on a standard 80C51 core, providing performance up to 15 times better at the same clock frequency. The T89SC256C has been designed to support a high security level. It includes several dedicated security features, such as a True Random Number Generator A program routine that produces a random number. Random numbers are created easily in a computer, since there are many random events that take place such as the duration between keystrokes. , a Secure Memory Management Unit, a memory error detection and correction (algorithm, storage) error detection and correction - (EDAC, or "error checking and correction", ECC) A collection of methods to detect errors in transmitted or stored data and to correct them. This is done in many ways, all of them involving some form of coding. automatic mechanism, and physical sensors. A watchdog timer A clock circuit that keeps counting from a set number down to zero. If the event it is monitoring occurs before it reaches zero, it resets to the starting number and starts counting down again. has also been included in this product to control the correct execution of the embedded application software. For high-speed cryptography computation capacity, a separate Arithmetic Crypto Co-Processor is provided on the chip. It supports up to 2048-bit RSA (1) (Rural Service Area) See MSA. (2) (Rivest-Shamir-Adleman) A highly secure cryptography method by RSA Security, Inc., Bedford, MA (www.rsa.com), a division of EMC Corporation since 2006. It uses a two-part key. computation. A 1024-bit RSA computation with Chinese Remainder Theorem (CRT (1) (C RunTime) See runtime library. (2) (Cathode Ray Tube) A vacuum tube used as a display screen in a computer monitor or TV. The viewing end of the tube is coated with phosphors, which emit light when struck by electrons. ) is achieved in 90 ms. Frederic Chevreton, vice-president and general manager of Atmel's Microcontrollers & Digital Products Business Center, said, "We are very proud to offer this highly secure microcontroller. This is the first one on the market to combine the very large embedded Flash memory size, with high security features. Our customers can now benefit from all advantages linked to this technology, such as flexibility of use, full set of security features, short time-to-market, giving them a definitive step forward to develop further innovative applications." Many smart card and secure system applications will take advantage of this outstanding product. Atmel expects strong demand in high-end mobile phone applications, multi-application smart cards, secured data storage (e-book...), and secured card readers. Therefore a wide range of different delivery packages are available. Samples are available now. Typical price is $7 for 100K pieces.
