GENERAL DESCRIPTION
The MC68HC05CL48 HCMOS Microcontroller is a member of the M68HC05
family of low cost single chip microcontrollers. It is particularly suitable as a Caller
ID telephone controller. This 8-bit microcontroller unit (MCU) contains on-chip
oscillator, CPU, RAM, ROM, I/O, Timer, Watchdog Timer, SPI, A/D, Caller ID
subsystem, LCD driver and a 32kHz PLL.
1.1
FEATURES
Industry standard M68HC05 8-bit CPU core
