General Description
MOTOROLA
1.3 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)
1.4 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, Motorola’s strategy is to make reading or
copying the ROM difficult for unauthorized users.
