Silicon Storage 8051-based MCU with two system management buses

Silicon Storage Technology has added to its FlashFlex family of 8-bit microcontrollers with its first 8051-based MCU to feature two system management buses (SMBus), each supporting up to 400kbit/s data throughput, in a 6x6mm QFN package.

The SST89C58RC supports operating voltages from 2.7V to 5.5V.

According to the supplier, the dual hardware SMBus interfaces let the SST89C58RC act as an intermediary between a host processor and a complex multi-chip A/V subsystem.

The MCU is suitable for bundled applications, shielding the host from low-level interrupts while providing it with a 'virtual' register interface for simplified control and status access.

The SST89C58RC comes with 1kbyte of on-chip RAM and up to 34kbyte of embedded SuperFlash memory.
