A single-board computer with all basic inputs and outputs based on a singlechip microprocessor MPC555. Thanks to a unique time processor TPU is this unit aimed mainly on applications requiring very low lag. All pins are connected to a terminal plate to ease testing and expansion.

• GPS receiver Motorola Oncore M12
• accelerometer ADXL202e
• CAN bus: 2 channels with 82C250
• 2xRS232
• 4x opto-isolated data inputs
• external RAM , 16bit x 128kB, optional 256kB/512kB
• external FLASH, two 29lv081-8bit, optional 2MB/4MB
• serial EEPROM, 93C66
• optional headers with all MPC555 pins, (I/O piny a TPU)

It can be said the TPU is a processor inside a processor. TPU is a powerful unit with 16 input/output channels. This unit is used to handle fast pulses and to create rapid response given a preprogrammed function. These are for example:

• stepper motor control (two and three phase, up to 4 steppers simultaneously)
• Hall probe detection for stepper motor setup
• startup of stepper motors
• PCM (also synchronized with signal in another channel)
• PWM
• UART (word length is programmable from 1 to 14 bits, parity/no parity check, speed up to 100 kBbps
