Low-cost STM32 range

14 April 2010 DSP, Micros & Memory

STMicroelectronics has released details of new low-cost 32-bit microcontrollers bringing the features of the STM32’s 32-bit core to typical 16-bit applications such as home entertainment products, appliances and industrial equipment. ST’s new STM32 Value Line combines a 24 MHz ARM Cortex-M3 processor delivering up to 30 DMIPS with zero wait state embedded Flash memory access.

Application-focused features include up to twelve 16-bit timers, including a PWM timer for motor control applications. As many as 26 timer channels are available, with package options providing up to 100 pins, as well as a 12-bit high-speed ADC, to meet a wide range of industrial control challenges. ST is also offering free software support, including a complete three-phase motor control library for appliance and motor control applications and free VDE-certified libraries to help household appliances achieve necessary approval to EN/IEC60335-1 Class B.

The new family also embeds hardware support for the Consumer Electronics Control (CEC) protocol included in the HDMI standard, thereby simplifying CEC implementation in products such as TVs, Blu-Ray players, PVRs and home cinema equipment. CEC allows up to 10 HDMI devices to discover each other and communicate to manage user-convenience features such as one-touch control of multiple devices via a single remote. Implementing CEC in hardware also frees the processor core to perform extra high-level functions. In addition, a 12-bit DAC allows developers to add audio support in a variety of applications such as security devices or home automation systems, and to address wider opportunities requiring analog waveform generation and control.
