New 32-bit MCUs from STMicroelectronics with external SRAM and flash interface

STMicroelectronics has introduced its STM32 Value High-Density microcontrollers featuring extra program memory.

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

"The latest STM32 Value High Density devices build on the STM32 Value Line to set an even more exciting price-competitive entry point to 32-bit microcontroller design," said Michel Buffa, General Manager of ST's Microcontroller Division. "Cost-sensitive applications can now benefit from Flash memory density as high as 512 Kbytes for program and data storage, as well as extra integrated features."


Major features of STM32 Value High Density Line, include:
24MHz processor; 1.25 DMIPS/MHz
256 to 512 Kbytes Flash
24 to 32 Kbytes SRAM
12 x 16-bit timers including motor-control timer
12-bit ADC with 1.2us conversion time
