Small-form-factor device is ideal for battery-powered space- and height-constrained mobile applications where performance, reliability and low power consumption are crucial.
8051-based MCU has dual-bus structure
Dual hardware SMbus interfaces let the SST89C58RC act as an intermediary between a host processor and a complex multichip A/V subsystem.
SST's 8Mbit serial Flash device features a 33MHz maximum clock frequency and a typical standby current of only 8uA, thus significantly improving performance while lowering power consumption.
The 33MHz clock frequency has also been extended to SST's 2 and 4Mbit serial Flash devices, which are also currently available in volume production.
The company expects to add the 33MHz speed option to its 1Mbit and 512Kbit serial Flash devices in the second half of 2004.

The products in the 34WA series use a 6 x 8 x 1mm semiconductor package, making them the smallest address/data bus multiplex combination memory devices available on the market today.
SST's 8Mbit serial Flash device offers several advantages not available in alternative solutions, including an auto address increment (AAI) operation and small sector erase capability.
The 8Mbit serial Flash memory device is offered in a small footprint, 8-pin SOIC package with 200mm body width.
"Our 8Mbit serial Flash memory devices offer an optimum balance of features, performance and package size for a variety of applications", said Michael Briner, Senior Vice President of SST's Application Specific Product Group.
"Delivering our 8Mbit serial Flash devices in a 33MHz maximum clock frequency and in an 8-pin package enables SST to deliver a high-performance serial Flash solution that helps reduce overall system cost by saving board space and eliminating costly redesigns with density migration".
SST's serial Flash memory products incorporate a four-wire, SPI-compatible interface.
When compared with other nonvolatile memory interfaces, the SPI-interface serial Flash products use fewer pins to transfer data to and from a system CPU, thereby creating an overall reduction in board space, power consumption and cost.
Like all of SST's products based on SuperFlash technology, the SST25LF080A, features small sector erase capability, allowing designers to seamlessly partition code or data into 4Kbyte sectors, resulting in faster write times and an overall increase in system performance.
Because of its low power consumption and small footprint, the SST25LF080A is an ideal code storage solution in applications such as hard disk drives, wireless and networking equipment.
SST's 8Mbit serial Flash memory devices feature a unique AAI fast-programming mode, enabling a reduction in total Flash memory programming time by up to 50% when compared with single-byte programming modes.
The AAI programme instruction allows multiple bytes of serial Flash memory to be programmed without re-issuing subsequent addresses and commands after the first data byte programme sequence.
As a result, new programmes can be loaded into Flash using fewer commands, thus reducing programming times.
This advantage is especially useful during the manufacturing process, where fast production line throughput is essential.
SST's 25 Series of serial Flash memory products range in density from 512Kbit to 16Mbit, all containing the same footprint, providing customers with a seamless migration path to higher densities for their systems.
This capability allows designers to create product lines with new levels of functional flexibility and dramatically lower system costs when compared to systems using parallel Flash products housed in traditional 32- or 48-pin packages.
The 8Mbit SST25LF080A is available now in volume production, and is priced at $1.70 in 100,000-unit quantities.
