General Description
1.1 Introduction
The MC68HC05C9E HCMOS (high-density complementary metal-oxide semiconductor) microcontroller
is a member of the M68HC05 Family. The MC68HC05C9E memory map consists of 15,936 bytes of user
ROM and 352 bytes of RAM. The MC68HC05C9E includes a serial communications interface, a serial
peripheral interface, and a 16-bit capture/compare timer.
1.2 Features
Features of the MC68HC05C9E include:
• M68HC05 CPU
• Mask programmable interrupt capability on port B
• Software programmable external interrupt sensitivity
• 15,936 bytes of read-only memory (ROM)
• 352 bytes of random-access memory (RAM)
• Memory mapped input/output (I/O)
• 31 bidirectional I/O lines with high current sink and source
on PC7
• Asynchronous serial communications interface (SCI)
• Synchronous serial peripheral interface (SPI)
• 16-Bit capture/compare timer
• Computer operating properly (COP) watchdog timer and clock monitor
• Power-saving wait and stop modes
• On-chip crystal oscillator connections
• Single 4.5 volts to 5.5 volts power supply requirement
• ROM contents security(1) feature
• Available packages:
– 40-pin dual in-line (DIP)
– 44-pin quad flat pack (QFP)
1.3 Mask Options
Eight mask options are available to select external interrupt capability (including an internal pullup device)
on each of the port B pins.
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or copying the ROM difficult for
unauthorized users.
