MDK-ST10 control board
The MDK-ST10 control board is used to demonstrate the capabilities of the ST10F276
microcontroller and to provide a hardware tool allowing applications development.
ST10F276 is a 16-bit MCU with MAC unit (DSP features), 832 Kbytes of flash memory and
68 Kbytes of RAM. Its main characteristics are: 64MHz CPU, 31.25ns instruction cycle,
multiply/accumulate unit (MAC) with 40-bit accumulator 8 PWM channels, 24 A/D converter
channels (10-bit 3µsec of conversion time), CAP/COM peripherals with 16-bit timer
(100nsec of maximum resolution, 111 GPI/O, I2C, SCI, 2 CAN peripherals. The architecture
of the micro is shown in Figure 18. Please refer to ST10F276 datasheet or user manual for
more details.
The MDK-ST10 is an evaluation module board that includes a ST10F276 part, peripheral
expansion connectors (3 general purpose motor connectors + 1 standard MC connector
vector control-based) and CAN interface. The expansion connectors have been placed for
signal monitoring and user feature expandability.
