GENERAL DESCRIPTION
The MC68HC05SB7 HCMOS microcontroller is a member of the M68HC05 family
of low-cost single-chip microcontrollers. This 8-bit microcontroller unit (MCU),
which contains an internal oscillator, CPU, RAM, ROM, personality EPROM, I/O,
16-bit timer, core timer, watchdog system, LVR, SM-Bus, PWM, current sense
amplifier, internal temperature sensor and A/D, is designed specifically for smart
battery applications.
