TELECOMWORLDWIRE-30 June 2008-SST release MCU with dual SMBus(C)1994-2008 M2 COMMUNICATIONS LTD http://www.m2.com

Silicon Storage Technologies Inc (SST), which manufactures and markets memory and non-memory products for high volume applications, announced on 30 June that it has released a new addition to its FlashFlex family of microcontrollers (MCUs). The SST89C58RC is an 8051-based MCU, featuring two system management buses (SMBus), each having a maximum data throughput of 400Kb/s.

The new chips, in a 6mm x 6mm QFN form factor, support voltages between 2.7V to 5.5V and are designed for a wide range of applications, including HDMI, HDTVs, A/V receivers, home appliances, industrial instruments, notebook PCs, DVD players, Blu-ray players, RF modules and security applications such as fingerprint identification.

With its dual SMBus, the SST89C58RC can act as an intermediary between a host processor and complex multi-chip A/V systems, shielding the host from low-level interrupts and providing a 'virtual' register interface for status access and simplified control.

The MCU is delivered with up to 34Kb of on-chip SuperFlash non-volatile ROM and 1Kb RAM and is pin-for-pin compatible with standard 8051 MCUs. The onboard flash memory can be reprogrammed or updated via hardware or software, giving implementers the opportunity to install the MCU in systems that may require remote updating via a network or internet connection.

The SST89C58RC is available at USD1.25 per unit in 10K unit quantities.
