Geneva, July 13,2006 - STMicroelectronics today announced four new 16-bit Flash microcontrollers for their popular ST10 family, the ST10F27x series. The new MCUs (microcontrollers) offer up to 832-KBytes of embedded Flash memory and up to 68-kbytes of RAM.

The ST10 family is one of the few product ranges to combine embedded Flash and the -40 to +125 degrees C temperature range.

The new ST10F271, ST10F272, ST10F273 and ST10F276 provide a range of Flash memory densities from 128- to 832-KBytes. Total linear address space for code and data is 16 Mbytes. ST has now delivered more than 100 million chips based on the ST10 core.

The ST10 family is based on an advanced register based full 16-bit CPU, The CPU runs at up to 64MHz, with single cycle context switching and a programmable interrupt controller with 16 priorities and 56 sources. The core also includes a powerful DSP-MAC (multiply/accumulate) unit.

These new devices are targeted for:

  • Industrial applications
  • Motor control
  • Vector drives and inverters
  • Power converters
  • Positioning systems
  • Motorized lift control
  • Factory automation
  • Circuit breakers
  • Electric vehicles
  • Medical applications such as endoscopes and breathing aids

Powerful and Large Flash Memory
The ST10 uses ST Microelectronics' proprietary high-quality embedded Flash memory, guaranteed for 100,000 Program/Erase cycles and 20-year data retention. The flash memory uses ST’s latest 0.18µm process technology spec'ed at  the -40 to +125 degrees C temperature range

Memory protection guards against software piracy.

Devices operate off a single 5V power supply, with 5V I/O levels. An internal 1.8V voltage regulator supplies the CPU core and logic.

The wide set of ST10 peripherals includes:

  • An I2C interface
  • Improved real-time clock (RTC) with a 32kHz on-chip oscillator
  • A/D Converter channles increase from 16 to 24 channels
  • Multiple Input Capture and Compare (CAPCOM)
  • 4-channel PWM (Pulse Width Modulation) unit
  • 10-bit ADC
  • Peripheral Event Controller (PEC)
  • dual CAN 2.0B interfaces

All the new MCUs are produced in both the LQFP144 20x20mm package and the PQFP144 28x28mm package.

Pricing and Availability
The ST10F273 and ST10F276 are in volume production. The ST10F271 and ST10F272 are sampling now with volume production planned for Q3 2006.

The ST10F27x family is 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.
