Atmel Introduces a New Flash C51 Microcontroller With CAN Controller for Cost-Effective Industrial and Automotive Applications.Business Editors/High-Tech Writers NANTES, France--(BUSINESS WIRE)--May 16, 2001 Atmel(R) Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) announced today the expansion of its CAN-based microcontroller family (CANary(TM)) by introducing the T89C51CC02. Retaining most of the existing T89C51CC01 features, the T89C51CC02 is a low pin count version with 16-Kbyte on-chip Flash program memory and 4 message objects CAN controller. This new device is ideally suited for cost-effective and high-volume applications in the industrial and automotive markets and is fully compatible with the ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. specifications 11898 (2.0A & 2.0B) for high speed and 11519-2 for low speed serial data bus transmission. The T89C51CC02 offers an advanced In-system Programming (ISP (1) See in-system programmable. (2) (Internet Service Provider) An organization that provides access to the Internet. Connection to the user is provided via dial-up, ISDN, cable, DSL and T1/T3 lines. ) capability, via CAN bus or 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 , to designers needing to develop applications where product flexibility, programming security, short time-to-market and low costs are required. In addition the T89C51CC02 has a unique Flash architecture which ensures a high security level during the ISP operations. Because the 2-Kbyte Flash boot memory and the program memory are physically separate, the programmer can modify the Flash boot memory in parallel mode only, avoiding any mishandling of its content during ISP operations. The T89C51CC02 supports existing CAN networks with 2.0A and 2.0B nodes, as each of the 4 message objects may be used in one of these two modes. Each message object is programmable for reception, transmission or receive buffer (maximum 32 Bytes) and has its own masking and filtering registers, which drastically reduces the host processor load. Philippe Malecha, marketing director for Customer and Application Specific Products at Atmel Wireless and Microcontrollers Division, said, "we are now extending our CANary(TM) family with a new device that provides cost-effective solutions for CAN protocol control with flexible Flash memory. With In-system Programming capability, the T89C51CC02 is an ideal solution as it allows application upgrade at any stage of the product lifetime. This is a definitive step forward for further innovative CAN multiplexing networks and answers customers' needs to reduce time-to-market." An important feature in the T89C51CC02 is its internal clock doubler. This allows it to achieve the maximum CAN bus data rate of 1Mbit per sec, using only an 8MHz (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. crystal, thus drastically reducing emitted electromagnetic interference signals that could disturb other nearby subsystems. A dual data pointer, 2-Kbyte user data EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. , an 8 channel 10-bit ADC (1) See A/D converter. (2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. and a 512-byte RAM complete the C51 enhanced architecture of the T89C51CC02. A full set of support tools is also available. It includes hardware emulator and software compiler/simulator, starter kit, Boot Loader, all the required Application Protocol Interfaces (API) and an Atmel proprietary Flash loader Software called "FLIP." The T89C51CC02 is available in SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. 24, SOIC28, TSSOP TSSOP Thin Shrink Small Outline Package TSSOP Thin Scale Small Outline Package 28 or PLCC (Plastic Leaded Chip Carrier) A plastic, square, surface mount chip package that contains leads on all four sides. The leads (pins) extend down and back under and into tiny indentations in the housing. See chip package. 28 and in industrial temperature range (automotive temperature range is under qualification). Samples are available now. Price is $5.20 each for 10K pieces in industrial temperature range and SOIC28 package.
