GENERAL

The MC68HC05P15 is a 28-pin device based on the MC68HC05P5 with an on-chip analog voltage comparator and a two channel PWM. The memory map includes 3072 bytes of user ROM, 64 bytes of user EPROM, and 128 bytes of RAM. The MCU has two I/O ports, A and C, consisting of 15 pins with mask programmable pull-up resistors. Port B consists of 3 pins, 2 input only and 1 output only, shared with an analog voltage comparator. PWM circuitry does not share the output pins with any other module. Port D has 1 input only pin. The MC68HC05P15 has a 16 bit timer, a mask programmable Computer Operating Properly (COP) Watchdog, a mask programmable STOP disable option, and Illegal Address Reset (ILADR) circuitry to insure proper functioning of any system.
