Silicon Storage Technology has added to its FlashFlex family of 8-bit microcontrollers (MCUs), with the SST89C58RC. The new device is an 8051-based MCU featuring two system management buses (SMBus), each supporting up to 400 Kbps data throughput, in a tiny 6 x 6 mm QFN package.
The SST89C58RC supports operating voltages from 2,7 V to 5,5 V for implementation in applications with a variety of power supply requirements. Its dual SMBus feature, small form factor and support for a wide range of operating voltages make it a particularly suitable solution for numerous 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.
The SST89C58RC is the latest member of the FlashFlex family of 8-bit microcontroller products with patented and proprietary SuperFlash non-volatile Flash memory cells. SuperFlash memory uses a split-gate cell design and a thick-oxide tunnelling injector to offer cost and reliability benefits.
All devices in the FlashFlex family use the 8051 instruction set and are pin-for-pin compatible with standard 8051 microcontroller devices. In addition, all devices in the FlashFlex family feature in-system programming (ISP) and in-application programming (IAP) to allow for maximum design flexibility by enabling the user to update the Flash device in the field or in an application. These re-programming features also have a significant role in enabling increased functionality, such as remote diagnostics and product monitoring, in network- or Internet-enabled devices.
The SST89C58RC comes with 1 Kbyte of on-chip RAM and up to 34 Kbytes of embedded SuperFlash memory.
