Motorola introduces 68HC05 expanded memory microcontroller ideal for general purpose applications; external address data bus addresses up to 64K of external memeory.AUSTIN, Texas--(BUSINESS WIRE)--Feb. 21, 1995--Motorola's Customer Specified Integrated Circuits (CSIC (Customer Specific Integrated Circuit) Pronounced "c-sick." Another term for ASIC, which was coined by Motorola. Some feel this is a more accurate description of an ASIC chip. See ASIC. ) Microcontroller Division Tuesday announced a new version of its popular 68HC05 family of microcontroller units (MCUs). The new device, the 68HC05C0, is an "expandable" microcontroller that can address up to 64K bytes of external memory. This flexible general purpose device features a wide array of memory options capable of handling complex programs in automotive, telecommunications, consumer, industrial and computer applications which require an external address and data bus. In fact, it can be used in virtually any application requiring external memory. The 68HC05C0 is a low-cost solution enabling development of low-cost systems. The device has up to three chip selects which differentiates it from others in the field. It provides direct interface to existing memory with no glue logic (non-multiplex mode & chip selects). Scott Anderson, vice president and general manager for Motorola's CSIC Microcontroller Division, noted, "Since it addresses external ROM, the 68HC05C0 is available as an off-the-shelf product which can speed application development and product time-to-market." Based on Motorola's industry-standard 68HC05 core, the 68HC05C0 provides a mode select for either a multiplexed or non-multiplexed bus, and a clock-stretching capability for slower peripherals. The device contains an on-chip oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air , 4 MHz CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. bus rate for non-multiplexed mode and 2 MHz CPU bus rate fro multiplexed mode, 512 bytes of on-chip RAM, serial and parallel I/O, a multifunction timer, a 16-bit timer, and a low-voltage reset. The device is available in 40-pin DIP, 42-pin SDIP See Shrink DIP and Skinny DIP. and 44-pin 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. packages. On-chip Serial Communications Interface Serial Communications Interface - UART (SCI (Scalable Coherent Interface) An IEEE standard for a high-speed bus that uses wire or fiber-optic cable. It can transfer data up to 1GBytes/sec. (hardware) SCI - 1. Scalable Coherent Interface. 2. UART. ) provides asynchronous communications, with selectable baud rates from 75 Hz to 131 kHz. A SCLK Noun 1. SCLK - the clock time given by a clock carried on board a spacecraft spacecraft clock time clock time, time - a reading of a point in time as given by a clock; "do you know what time it is?"; "the time is 10 o'clock" signal provides synchronous communication when needed. All 68HC05 C Series devices include a 16-bit free-running programmable counter in conjunction with input capture and output compare functions for simultaneous input waveform measurement and output for waveform generation. In addition, the 68HC05C0 includes a multifunction timer with real-time intercept (RTI RTI - Return from interrupt ) and COP (watchdog) capability which guards against runaway software in noisy environments. Price and Availability Motorola's 68HC05C0 is available in the second quarter of 1995. The product is priced at $2.20 in High Volume OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and quantities. Production of development systems will also be in the second quarter of 1995. The CSIC Division is a business unit within Motorola's Microcontroller Technologies Group, with headquarters in Austin. Having 1994 worldwide sales of $6.9 billion, Motorola's Semiconductor Products Sector is the largest U.S.-based broad line supplier of semiconductors, with a balanced portfolio of more than 50,000 devices. Motorola is one of the world's leading providers of wireless communication, semiconductors and advanced electronic systems and services. Major equipment businesses include cellular telephone, two-way radio, paging and data communications, personal communications, automotive, defense and space electronics and computers. Communication devices, computers and millions of consumer products are powered by Motorola semiconductors. Motorola's 1994 sales were $22.2 billion. -0- Response Material: HC05C0GRS/D 68HC05C0 Features --HC05 Core --40-Pin PDIP (Plastic DIP) See DIP. , 42-pin SDIP, and 4-pin PLCC Packages --Mode Select for lower byte address/data muxed or non-muxed --4 MHz CPU bus rate for non-muxed mode, 2 Mhz for muxed mode --4 bus cycle clock stretching for slow peripherals --512 bytes of on-chip RAM --16-bit timer with input capture and output compare --Up to 18 bi-directional I/O (Input/Output) The transfer of data between the CPU and a peripheral device.
