GENERAL DESCRIPTION
1.1 Introduction
This MC68HC(7)05CJ4 is a 44-pin microcontroller unit (MCU) with highly
sophisticated on-chip peripheral functions. The memory map includes nearly 4
Kbytes of user ROM or EPROM and 224 bytes of RAM. The MCU has four ports:
A, B, C, and D. Ports A, B, and C are bidirectional, and port D is output only,
supporting several multifunction pins. The MC68HC05CJ4 has two timers, a COP
watchdog, a serial peripheral interface (SPI), a serial communications interface
(SCI), and a slave-only I2C Bus.
