Microprocessor available in 110-MHz speed grade. The MicroSPARC-II is available in a 110-MHz version, which improves on previously available 70- and 85-MHz versions. The processor provides 76SPECint and 65SPECfp performance. The 110-MHz version costs $649 (1000). Sun Microsystems Inc, Mountain View, CA. (800) 821-4643.
16-bit microcontrollers available in 3.3V and industrial-temperature versions. The Am186EMLV and AM188EMLV are software- and peripheral-set-compatible with the 80C186, but operate from 3.3V. The devices start at $8.86 (10,000). The extended temperature versions of the AM186EM-I and AM188EM-I operate from –40 to +85°C and start at $9.67. Advanced Micro Devices Inc, Sunnyvale, CA. (408) 749-5703.
16-bit µC has controller-area-network interface. The SABC167CR has an on-chip controller-area-network (CAN) interface with a separate CAN-module controller. The controller contains 15 message objects that perform error checking and send/receive messages, relieving the µC from performing these tasks. The µC also has a 10-bit ADC with 16 analog input channels, 4 kbytes of on-chip RAM, 111 I/O lines, an address range of up to 16 Mbytes, four independent channels of 78-kHz PWM, 32 independent capture-and-compare channels, an extended interrupt system, and a PLL oscillator with an internal multiplier for 20-MHz operation from a 5-MHz clock. The µC costs $35 (1000). The SABC167SR without the CAN interface costs $31 (1000). Siemens Components Inc, Integrated Circuits Division, Cupertino, CA. (408) 777-4500.
8-bit microcontroller offers high speed and large program memory. The PIC17C44 one-time-programmable microcontroller is available with cycle times as low as 160 nsec for the 25-MHz version. The device performs an 88 unsigned hardware-multiply instruction in a single cycle. The chip has an 8k 16-bit program memory and 454 bytes of user RAM. An on-chip PWM operates at 97.7 kHz with 8-bit resolution and 24.4 kHz with 10-bit resolution. A serial communications interface (USART) which you can configure as a full- or half-duplex synchronous system, can communicate with other microcontrollers or peripheral devices at speeds up to 6.25 Mbps. A 16-MHz version costs $11.13 (1000). Microchip Technology Inc, Chandler, AZ. (602) 786-7200.
