MC705P6AMDWE Description
The microcontroller MC68HC05P6 has an EPROM variant called the MC705P6AMDWE. 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 make up this low-cost assembly. The M68HC05 CPU core has 21 input/output (I/O) pins (20 bidirectional, 1 input-only), 176 bytes of RAM, 4672 bytes of user EPROM, and 239 bytes of bootloader ROM. The 28-pin plastic dual in-line (PDIP) or 28-pin small outline integrated circuit (SOIC) packages are both available for this component.
