The MC68HC(7)08KH12 is a member of the low-cost, high-performance
M68HC08 Family of 8-bit microcontroller units (MCUs). The M68HC08
Family is based on the customer-specified integrated circuit (CSIC)
design strategy. All MCUs in the family use the enhanced M68HC08
central processor unit (CPU08) and are available with a variety of
modules, memory sizes and types, and package types.
Features of the MC68HC(7)08KH12 include the following:
•
High-Performance M68HC08 Architecture
•
Fully Upward-Compatible Object Code with M6805, M146805,
and M68HC05 Families
•
6 MHz Internal Bus Operation
•
Low-Power Design (Fully Static with Stop and Wait Modes)
•
12 KBytes of User ROM (MC68HC08KH12) or One-Time
Programmable (OTP) ROM (MC68HC708KH12)
•
On-Chip Programming Firmware for Use with Host Personal
Computer
•
ROM/OTPROM Data Security
•
384 Bytes of On-Chip Random Access Memory (RAM)
•
42 General Purpose I/O, 29 with Software Configurable Pullups
•
16-Bit, 2-Channel Timer Interface Module (TIM)
•
20-Bit Keyboard Interrupt Port
•
5 LED Direct Drive Port Pins
•
48MHz Phase-Locked Loop
1. No security feature is absolutely secure. However, Freescale's strategy is to make reading or
copying the ROM/OTPROM difficult for unauthorized users.
