NXP Semiconductors MC9S08SU 8-bit Microcontroller
NXP Semiconductors MC9S08SU 8-bit Microcontroller (MCU) offers a single-chip solution for low-end 4.5V to 18.0V motor control applications with a low BOM cost and tight integration. Based on the HSC08 core, the MC9S08SU MCU achieves high performance while maintaining low cost using the enhanced S08L central processor unit. The unit comes with 3-phase MOSFET pre-drivers unit that supports three high-side PMOSes and three low-side NMOSes, amplifiers for current measurement, over current protection (OCP), and over-voltage protection (OVP). The NXP Semiconductors MC9S08SU MCU is offered in a compact 4mm x 4mm QFN-24 package. The small size and reduced number of required components of the MC9S08SU make it ideal for space-constrained applications, such as power tools, drones, and robotics.
