Microchip: Standalone CAN Peripheral; New PICmicro with CAN

The new MCP2515 standalone CAN peripheral chip gives designers a CAN solution that provides faster data throughput, efficient data-byte filtering, generates start of frame (SOF) output and uses an SPI™ interface, which enables an easy connection to virtually any microcontroller.

The MCP2515 has a 40MHz maximum clock-input speed and a 10MHz high-speed SPI interface. This faster throughput enables CAN messages to be processed and transferred to the host microcontroller much faster than the original device. Additionally, Microchip’s new Interface CAN device has the ability to filter messages based on the first two data-bytes and the 11-identifier bits. This feature reduces the microcontroller overhead requirements when supporting high-layer protocols, like DeviceNet ™ support, that utilize data-bytes in addition to identifier bits for determining whether CAN messages should be received and processed by certain notes.

Pricing for the MCP2515 in 1,000-unit quantities is $1.72 USD each

Microchip also announced the PIC18F8680/6680 and PIC18F8585/6585 devices. The devices feature the new ECAN™ module, a CAN 2.0B interface. The ECAN module features configurable transmit and receive (TX/RX) buffers that can be used for standard CAN operation or as FIFO registers.

With an operating range of 2.0-5.5 volts, the devices feature either 48K bytes or 64K bytes of Flash memory, 3K bytes of RAM memory and 1024 bytes of high-endurance EEPROM data memory. The feature-rich peripheral set includes an analog-to-digital converter (ADC) with up to 16 channels x 10-bit resolution, one capture/compare/PWM module and one enhanced capture/compare/PWM module capable of full H-bridge motor control functionality, one 8-bit timer, three 16-bit timers and one watch-dog timer (WDT) with extended time control mode of 10 minutes, dual analog comparators and a parallel slave port (PSP). Additional features include a programmable brown-out detection/reset (PBOR), programmable 16-level Low Voltage Detection module (PLVD), 32 kHz secondary oscillator clock input and a software-selectable 4x phase lock loop (PLL) for 10 MIPS performance at 10 MHz. Serial I/O features include CAN 2.0B, SPI™, I2C™, and an addressable USART module supporting RS485, RS232 and LIN interfaces.

Motorola: New HC08 Hybrids with Integrated MOS Motor Drivers and LIN Physical Layer

Motorola's new MM908E624 and MM908E625 devices combine high-performance flash microcontrollers (MCUs) with SMARTMOS™ analog integrated circuits (ICs) in a single package. Both include the LIN physical layer coupled with a flash MCU that integrates an enhanced serial communications Interface for simple yet flexible management of the LIN protocol. In addition, a special internal oscillator module in the MCU, called an internal clock generator, eliminates the need for an external quartz oscillator. Additional MCU features include dual timer channels, a 10-bit analog-to-digital converter and serial peripheral interface

The analog ICs on the MM908E624 and the MM908E625 are manufactured using Motorola's proprietary SMARTMOS process. This enables the combination of high-density/high-speed logic with precision analog and high-voltage/high-current power circuitry.

The MM908E624 includes the drivers and inputs necessary for high-current DC motor control using low-cost relays. Its analog IC features include three high-side outputs that allow direct control of automotive relays with a minimal number of external components.

With an analog IC that features four half-bridges and one high-side output, the MM908E625 allows for direct control of the motors used in door locks and other small motor control applications. In addition to running DC motors, the MM908E625 can be configured to run bipolar stepper motors in current control mode up to 500mA in size.

The analog ICs on both Intelligent Distributed Control devices also incorporate a watchdog timer and an advanced voltage regulator with the capability to enter a battery-saving low-power mode with system wake up via LIN or external inputs.

Sample quantities of both of the new Intelligent Distributed Control devices for LIN are currently available, with production quantities expected to be available in first quarter of 2004. The suggested list prices (USD) for 10,000-piece quantities are $3.95 for the MM908E624 and $4.95 for the MM908E625.

No LIN bus synchronization code is needed in the QL4 software and no trimming of the internal oscillator is required to communicate.

The QL4's LIN interface design helps to reduce system interrupts by more than 80% over UART solutions. It also has the smallest driver code required to process LIN messages. Like existing "Q" HC08 devices, the QL4 incorporates 4 KB of Flash. Other standard features include an integrated internal oscillator, a watchdog, low voltage interrupt, keyboard interrupt, LED drive capability and a 6-channel 10-bit ADC.

Designed for one- and two-motor control in appliances such as air conditioners, washers, dryers and refrigerators, the V850E/IA3 and V850E/IA4 achieve a performance of 82 (Dhrystone 1.1) MIPS at 64MHz.

The V850E/IA3 and V850E/IA4 MCUs feature a 60 percent improvement in instruction speed over previous members of the V850E/IAx™ family. In addition, the built-in ROM has been expanded from 128 to 256 KB. Both the 256 KB flash ROM and the 128 KB mask ROM are available for the V850E/IA3 device. The V850E/IA4 MCU has an additional 256 KB of mask ROM available. RAM size has also been increased from 6 to 12 KB.

To further improve motor and inverter control functionality, pulse-width modulation (PWM) timers were embedded, as were two high-speed 10-bit A/D converters with 2-microsecond conversion speed and a delta-sigma A/D converter. An operational amplifier (op-amp) and comparator also have been added on-chip to reduce system costs.

Engineering samples will be available October 2003 for both devices. Samples are priced at $20 each for the V850E/IA3 and $25 each for the V850E/IA4. Mass production for both is scheduled to start July 2004.
