The product lines comprise variants with combinations of an integrated USB controller, an LCD controller, and cryptography for security applications. According to ST, 256kbyte of flash and low pin count package choices make them ideal for cost-sensitive applications.
The devices also offer digital peripherals, including a True Random-Number Generator and smart analogue features, such as a 12bit 5Msample/s A/D converter, internal voltage reference, and ultra-low power comparators.
All devices include FlexPowerControl, with features such as separate supply voltage domains for gating power individually, analogue peripherals, USB circuits, and I/Os. Batch Acquisition Mode enables energy efficient data capture, and seven reduced power modes with further sub-modes maximize energy savings in a range of operating conditions.
The devices are available in small form factor packages from 5 x 5mm QFN-32 to 14 x 14mm LQFP-100, including 3.14 x 3.13mm WLCSP.
