Crossware Adds Support for 64 Silicon Labs 8051 Chips

Crossware has enhanced its 8051 C- Development Suite by adding support for an additional 64 chips across 10 families in the Silicon Laboratories mixed signal microcontroller (MCU) range.

The chips supported include the recently introduced C8051T610 family of small-form-factor low-cost 8-bit MCUs. Also supported are the F320, F330, F340, F350, F360, F410, F520, F530 and T600 families of MCUs.

The Crossware enhancements allow developers to rapidly exploit the advanced features of these chips by providing a combination of wizards, simulation, debugging, compiler extensions and pre-configuration. This allows the programmer to accelerate the development process and significantly reduce new product time-to-market.

Crossware's Code Creation Wizards are provided for all on-chip peripherals, and many are able to generate configuration code, interrupt routines and, for the UARTs, complete I/O handlers. The simulator simulates the 8051 core itself as well as many of the on-chip peripherals. This allows a developer to use the simulator to immediately test the code created using the wizards. The simulator can also be extended using the Virtual Workshop Interface allowing developers to construct a simulation of their complete target system.

The 64 additional chips now supported by Crossware include the following: C8051F330/1/2/3/4/5, C8051F340/1/2/3/4/5/6/7, C8051F350/1/2/3, C8051F360/1/2/3/4/5/6/7/8/9, C8051F410/1/2/3, C8051F520/1/3/4/6/7, C8051F530/1/3/4/6/7, C8051F326/7, C8051F336/7/8/9, C8051T600/1/2/3/4/5 and C8051T610/1/2/3/4/5/6/7.

This performance, coupled with on chip timers, makes these devices ideal for motor control applications. The devices also are designed to enable simplified development of LIN systems through an on-chip serial communications interface (SCI). The SCI module allows LIN break detection and synchronization without the use of an external timer channel.

Other notable features include low-voltage inhibit (LVI) circuits, voltage regulators, I/O multiplexers, watchdog circuits and analog-to-digital converters (ADCs).

The S08SG16/32 devices offer an on-chip background debug mode (BDM) capability that enables developers to perform non-intrusive debugging and emulation on the fly.

Samples of the S08SG16/32 devices are available now.

Fujitsu Introduces MCU integrating SMSC MediaLB Interface

Fujitsu Microelectronics Europe and SMSC have announced the implementation of SMSC's Media Local Bus (MediaLB) technology in the latest member of Fujitsu's 32-bit MB91460 microcontroller product series, the MB91F467M. These microcontrollers are designed to support high-performance automotive and industrial applications to ensure fast data processing and distribution. The MediaLB serial bus interface provides seamless connectivity to SMSC's Media Oriented Systems Transport (MOST) Intelligent Network Interface Controller (INIC) family.

The MB91F467M is a member of Fujitsu's MB91460 range of controllers designed for automotive applications including body control, dashboard and/or infotainment. The MB91F467M targets car audio applications and acts as a gateway between the MOST bus, via its MediaLB interface, and up to 10 I2S interfaces. In addition to data, MediaLB also provides a clock path with extremely low jitter from the MOST backbone to or from those interfaces.

The MediaLB function block allows 256fs and 512fs operation. It contains a buffer of 2048 x 32 bits and offers support for 16 channels.

SMSC's MediaLB is an inter-chip communication technology that gives applications access to the MOST network by connecting them to an INIC. MOST technology is a de facto industry standard for automotive multimedia networking of high-bandwidth audio, video and control information or network data, enabling applications to communicate with minimum effort. MediaLB is also designed to support future MOST networks, thereby providing a simple migration path from existing MOST architectures to next-generation platforms.

The MB91F467M is optimised for applications requiring 32-bit performance at up to 80MHz and various communication interfaces. In addition to the MediaLB I2S gateway, it features two CAN controller interfaces with 32 and 64 message buffers, nine LIN-USART modules for synchronous and asynchronous serial communication, including LIN support, and eight dedicated I2C interfaces, which can act as master or slave modules. A variety of timers, a 10-bit ADC with 12 channels and a 16-bit external bus interface, complete the set of functions.

The on-chip memory includes 1088kB of Flash, 64kB of RAM and an 8kB cache. Debugging is supported by the on-chip debug support unit, which can be connected to Fujitsu's ICE system. The MB91F467M is housed in an LQFP-216 package.

First samples will be available in the second quarter of 2008. Fujitsu will also offer its MB91460 support eco-system for this latest member of the MB91460 series.
