MetaLink Corporation has introduced support for the T89C51IC2 device from Atmel. The 8-bit T89C51IC2 MCU is based on the 80C51 core architecture, has 32K bytes of Flash memory along with an SPI interface, a 5 channel PCA and a 32KHz subsidiary clock oscillator. Support for the T89C51IC2 device will be provided by the MetaICE-XF family of emulators at $2000. MetaLink is now accepting orders. Delivery is one week ARO.

The MetaICE-XF is state of the art in 8051 emulator design with its combination of a small footprint, high speed and attractive features for a modest cost, providing a great value. The MetaICE-XF is one of the smallest full-featured emulators on the market, measuring just 3.3" (8,4 cm) by 3.0" (7,6 cm). The emulator includes the following standard features:

• 256 KB Code Memory / 256 KB External Data Memory
• 256 K Hardware Breakpoints
• 64 K Frames of Trace Memory with Time Stamp
• SFR Write Data in Trace Memory
• Monitored SFR’s (SP, IE, DPTR) in Trace Memory
• Bank Switching

The SFR Write Data and Monitored SFR’s trace features are unique to MetaLink emulators, though other emulator manufacturers may advertise similar features. The real-time nature of these features is what distinguishes the MetaICE-XF from other emulators. MetaLink can provide these features without stopping the processor, where other emulators may do this by using a succession of steps, stopping emulation at each step.

The SFR Write Data trace feature means that each direct data write to an SFR (Special Function Register) is captured in the trace memory. The Monitored SFR’s trace feature means that the value of SP, IE and DPTR is captured in the trace memory. These features allow a designer to track the status of these critical registers.
