MC68705P5 Datasheet | Motorola Semiconductor

® MOTOROLA Advance Information 8-BIT EPROM MICROPUTER UNIT The MC68705P5 Microputer Unit (MCU) is an EPROM member of the M6805 Family of low-cost single-chip microputers. The user programmable EPROM allows program changes and lower volume applications in parison to the factory mask programmable versions. The EPROM versions also reduce the development costs and turnaround time for prototype evaluation of the mask ROM versions, This 8-bit microputer contains a CPU, on-chip CLOCK, EPROM, bootstrap ROM, RAM, I/O, and a TIMER. Because of these Features , the MC68705P5 offers the user an economical means of designing an M6805 Family MCU into his system, either as a prototype evaluation, as a low-volume production run, or a pilot production run. HARDWARE Features - 8-Bit Architecture - 112 bytes of RAM - Memory Mapped I/O - 1804 Bytes of User EPROM - Internal 8-Bit Timer with 7-Bit Prescaler - Programmable Prescaler - Programmable Timer Input Modes - External Timer Interrupt - Vectored Interrupts - External, Timer, and Software - Zero-Cross Detection on INT Input - 20 TTL/CMOS patible Bidirectional I/O Lines (8 Lines are LED patible) - On-Chip Clock Generator - Master and Power-On Reset - plete Development System Support on EXORciser - Emulates the MC6805P2 and MC6805P4 (Except for VSB) - Bootstrap Program in ROM Simplifies EPROM Programming - EPROM Security Features (Hardware and Software) SOFTWARE Features - Similar to M6800 Family - Byte Efficient Instruction Set - Easy to...
