Lexington, Mass. STMicroelectronics has beefed-up its ST10 family of 16-bit microcontrollers with four new MCUs that offer up to 832-kbytes of embedded flash memory and up to 68-kbytes of RAM. The family combines embedded Flash and the -40 to +125 degrees C temperature range.
The new ST10F271, ST10F272, ST10F274, and ST10F276 provide a range of flash memory densities from 128- to 832-kbytes, enabling ST10/C16x users to choose the optimum configuration for their application. Total linear address space for code and data is 16 Mbytes.
The CPU, with a clock speed of up to 64MHz, offers single cycle context switching and an interrupt controller with 16 priorities and 56 sources, making it ideal for demanding real-time applications. The DSP-MAC (multiply/accumulate) accelerator provides powerful DSP functions with fast and easy implementation of custom algorithms, and is supported by a comprehensive mathematical library.
Targets Motor Control
The new devices are particularly suited to industrial applications,
including motor control, vector drives and inverters, power converters, positioning systems, lift control, factory automation, circuit breakers and
electric vehicles, where high-performance, combined with real-time capabilities are essential.
The peripherals of the earlier ST10F269, is further enhanced in the new devices with an I2C interface, improved real-time clock (RTC) with a 32kHz on-chip oscillator, and an increase from 16 to 24 channels in the number of A/D converter inputs. The strong combination of multiple Input Capture and Compare (CAPCOM), 4-channel PWM unit, 10-bit ADC, Peripheral Event Controller (PEC), digital I/Os and dual CAN 2.0B interfaces are a perfect fit for industrial applications such as inverter control.
All the new MCUs are produced in both the LQFP144 20x20mm package and the PQFP144 28x28mm package, and are supported by mature development tools from multiple sources. The ST10F273 and ST10F276 are in volume production now, while the ST10F271 and ST10F272 are sampling now with volume production planned for Q3 2006. The ST10F27x family is also available and qualified for automotive applications with specific automotive part numbers.
Prices for the LQFP144 devices range from $9.30 (ST10F271, 128KB Flash) to $14.85 (ST10F276, 832KB Flash) in quantities of 10,000; PQFP144 devices are priced at $9.85 (ST10F271) to $15.63 (ST10F276), also in quantities of 10,000.
