The ST8034T/ST8034AT/ST8034P/ST8034C devices are complete low-cost analog interfaces for asynchronous and synchronous smartcards operating at a supply voltage of 5 V or 3 V (or even 1.8 V in the case of ST8034P). The ST8034T/ST8034AT/ST8034P/ST8034C devices can be placed between the card and the microcontroller to provide all supply, protection, detection and control functions, with just a few external components.

The ST8500 is a fully programmable power-line communication (PLC) modem system-on-chip (SoC), which is able to run any PLC protocol in the frequency band up to 500 kHz. The device architecture has been designed to target CENELEC EN50065, FCC and ARIB compliant applications supporting all major PLC protocol standards such as ITU G.9904 (PRIME), ITU G.9903 (G3-PLC®) and many other possible PLC protocol specifications and evolutions.

The ST890 device is a low voltage, P-channel MOSFET power switch intended for high-side load switching applications. The switch operates with inputs from 2.7 V to 5.5 V, making it ideal for both 3 V and 5 V systems. The internal current limiting circuitry protects the input supply against overload. The thermal overload protection limits power dissipation and junction temperatures. The maximum current limit is 1.2 A. The current limit through the switch is programmed with a resistor from SET to ground. The devices are available in SO-8 and DFN8L (3 x 3 mm) packages.

The ST8R00 is a synchronous PWM step-up DC-DC converter. The device is able to provide an output voltage in the range of 6 to 12 V with an input voltage from 4 to 6 V. The high switching frequency (1.7 MHz) permits the use of tiny surface-mount components. In addition to the resistor divider to set the output voltage value, only an inductor and two capacitors are required. Moreover, a low output ripple is guaranteed by the current mode PWM topology and by the use of low ESR SMD ceramic capacitors. The device is available in a very small DFN8 (4 x 4 mm) package.

The device is a high voltage NPN transistor in monolithic special Darlington configuration, designed for applications such as electronic ignition for small engines (scooters, lawnmowers, chainsaws).

The ST9060C is a 28/32 V common source N-channel enhancement-mode lateral field-effect RF power transistor designed for broadband commercial, avionics and industrial applications at frequencies up to 1.5 GHz. The device can be used in Class A, AB and C for all typical modulation formats.
