32-bit Dev Kit Only $9.90

STMicroelectronics' is delivering its STM32 Value Line Discovery development kit (Fig. 1) for only $9.90. The STM32 microcontroller and the STM32 Value Line is based on Arm's Cortex-M3 architecture.

The module holds a 24MHz, 64-pin STM32F100RBT6B microcontroller with 128 Kbytes of flash memory and 7 channel DMA. The chip has seven PWM 16-bit timers plus three independent PWM 16-bit timers with complementary output and dead-time generation. On the analog side is a 12-bit dual channel DAC with DMA support and output buffers. Digital periphperals include Consumer Electronics Control (CEC) support that is a one-wire bidirectional serial bus. There is also an I2C interface, 12 Mbit/s SPI master and slave interface and a high speed, 3 Mbit/s USART. The chip has a factory trimmed 8 MHz RC oscillator and 40 kHz oscillator for the RTC and watchdog timers. The module includes a USB-based ST-LINK in-circuit debug interface. The headers provide access to all the pins and peripherals on the

There are 15 ready-to-run applications available on ST's website. The STM32 Discovery is supported by a range of downloadable tool chains including Atollic's TrueSTUDIO/STM32 Lite. Developers can also take advantage of Keil's Embedded Workbench for ARM and IAR's Microcontroller Development Kit.

STMicroelectronics has an impressive chip with its STM32 Value Line. The Discovery makes it easier to check it out.
