INTRODUCTION

The MC68HC11PH8 8-bit microcontroller is a member of the M68HC11 family of HCMOS microcontrollers. In addition to 48K bytes of ROM, the MC68HC11PH8 contains 2K bytes of RAM and 768 bytes of EEPROM. Making use of an 84-pin PLCC, or 112-pin TQFP package, a non-multiplexed expanded bus is a feature of this device. The timer system has been expanded to include three input captures, four output compares and a software selectable input capture or output compare. There are three 8-bit modulus timers, one of which may be used as a prescaler for the other two. The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit operational requirements. Other major features of this device are: 8-channel, 8-bit A/D converter, four PWM timer channels, wired-OR capability for keyboard interrupt, four LCD segment drivers and two SPI and two enhanced SCI subsystems. The MC68HC11PH8 is especially suitable for mobile communications and automotive applications.

Features

? Low power, high performance M68HC11 CPU core
