40 MHz S08L Based Microcontroller
MC9S08SU16 and MC9S08SU8 are low-cost, high-performance
and high integration UHV HCS08 8-bit microcontroller units
(MCU). It uses the enhanced S08L central processor unit with 3-
phase MOSFET pre-drivers unit which supports 3 high-side
PMOSes and 3 low-side NMOSes, amplifiers for current
measurement, OCP (over current protection) and OVP (over
voltage protection). It is put into a 4mm x 4mm 24-pin QFN
package, targeting drone electrical speed controller, low power
motor control, small form cooling fan control and portable tools.
