Entry-level 32-bit MCUs

2 February 2011 DSP, Micros & Memory

STMicroelectronics is targeting designers with high product-performance requirements at competitive prices with its STM32 Value High-Density microcontrollers (MCUs). These new MCUs offer extra program memory and on-chip functions, extending the range of the STM32 Value Line family to include devices from 16 to 512 KBytes of embedded Flash, providing a scalable alternative for cost-sensitive designs.

Among the new enhanced features of the family is an external memory interface, which can address numerous types of external code or data memory. The interface also supports a parallel interface mode for LCD screens with embedded controllers. This responds directly to the growing use of graphical LCD panels in products such as washing machines, audio/DVD players and RF remote controls. In addition, extra package options, with up to 112 I/O pins, help designers manage more intensive communications between the microcontroller and other system components, such as sensors, status indicators and wireless subsystems.

STM32 Value High Density devices also target professional applications, such as metering, motor control and user-interface control in industrial and medical equipment.
