GENERAL DESCRIPTION

The MC68HC05PD6 is a member of the MC68HC05 family of HCMOS

Microcontroller Units (MCUs). This sophisticated 80-pin MCU has 16k-bytes of

user ROM, 512 bytes of RAM, and eight parallel ports. Ports A, B, C, F, G, and H

have eight I/O pins, port D and E have 8 output-only pins. The MC68HC05PD6

includes a Time Base circuit, 8 and 16-bit timers, a COP Watchdog timer, LCD

drivers, serial communication interface and P-Decoder. It is targeted for

communication applications such as pagers.
