STMicroelectronics has introduced the STMicroelectronics STM32F0, a new family of microcontrollers based on the ARM Cortex-M0 core. The new STM32F0 family runs at 48MHz.

Features of the new Cortex-M0 microcontrollers include:

  Cortex-M0 core @ 48MHz

  Single Supply: 1.8V to 3.6V Vcc

  5?0?8A Stop mode

  2?0?8A Standby mode

  430nA Vbat mode with only RTC running and 20 RAM registers kept alive

  Up to 64 KBytes Flash

  Up to 8 KBytes RAM

  Hardware RAM Parity check

  CRC module

  Two Watchdog Timers (for Class B certification)

  One watchdog timer uses the low-speed internal clock and triggers if the main oscillator fails

  Calendar RTC

  One 32-bit Timer

  Up to six 16-bit Timers

  16-bit 3-phase Motor Control Timer

  Five channel DMA

  12-bit ADC ±2LSB

  12-bit DAC

  Two comparators

  I2C/SPI @ 1Mbps

  HDMI Consumer Electronics Control (CEC)

The STM32F0 series integrates hardware support for the HDMI Consumer Electronics Control (CEC) interface. This protocol is used in home multimedia devices and allows connections based on the latest industry-standard protocols while leaving the microcontroller's CPU, memory and peripherals free to perform other tasks. The CEC kernel can be independently clocked by a low-speed 32kHz external clock or internal 8MHz clock.

The 48MHz STM32F0 is rated at 38DMIPS and 68 CoreMark. Interrupts on the Cortex-M0 require 12 cycles. All peripherals are compatible with existing STM32 devices and all STM32 devices are pin-compatible.

ST is targeting the STM32F0 at the low-power, low-performance, interrupt conscious 8-bit and 16-bit microcontroller market.

From ST: "STM32 F0 microcontrollers are sampling now at the resale price of $0.95 for quantities of 1000 pieces to lead customers. Full production is scheduled for the beginning of Q2 2012, and the devices will be available in 32-pin UFQFPN32, 48-pin LQFP48 and 64-pin LQFP64 package options with 20-pin and 100-pin extensions soon to follow."
