New series Low-Cost ST7Lite MCU Family Includes Enhanced Timer and Interface Peripherals
STMicroelectronics (NYSE: STM) today announced a new series of 8-bit Flash microcontrollers within the low-cost ST7Lite family which add new embedded peripherals to the established ST7Lite feature set. The ST7FLITE3 MCUs introduce an enhanced 12-bit auto-reload timer and a master/slave LINSCI™ asynchronous interface into the 20-pin package, and mark a significant step forward in communication and control functionality for real-time, industrial, consumer and motor control applications.
Cost-sensitive automotive, motor control and home electronics systems to benefit from new features
The 12-bit timer offers four independent PWM (Pulse Width Modulated) output channels with programmable Dead Time generation, intended for use in half-bridge driving mode in motor control applications where PWM signals must not be allowed to overlap; a 2kHz to 4MHz frequency range; programmable duty cycles; polarity control; and programmable output modes.
The embedded hardware LINSCI asynchronous serial interface will enable smooth implementation of LIN (Local Interconnect Network) bus applications, in the automotive, industrial and appliance sectors. ST’s exclusive LINSCI is a hardware-enhanced SCI port designed to simplify software design, and to increase system performance by reducing CPU overhead. LIN is typically used in low-end automotive applications for communication between 12V intelligent sensors and actuators, but is also increasingly popular in industrial and consumer systems for reducing wiring complexity.
