Product Summary

The MC705P6ACDWE is an EPROM version of the MC68HC05P6 microcontroller. It is a low-cost combination of an M68HC05 Family microprocessor with a 4-channel, 8-bit analog-to-digital (A/D) converter, a 16-bit timer with output compare and input capture, a serial communications port (SIOP), and a computer operating properly (COP) watchdog timer. The MC705P6ACDWE CPU core contains 176 bytes of RAM, 4672 bytes of user EPROM, 239 bytes of bootloader ROM, and 21 input/output (I/O) pins (20 bidirectional, 1 input-only). The MC705P6ACDWE is available in either a 28-pin plastic dual in-line (PDIP) or a 28-pin small outline integrated circuit (SOIC) package.
