The MC68HC11P2 8-bit microcomputer is a member of the M68HC11 family of HCMOS microcomputers. In addition to 32kbytes of ROM, the MC68HC11P2 contains 1kbyte of RAM and 640 bytes of EEPROM. With its advanced timer and communication features (including MI BUS(1)) the MC68HC11P2 is especially suitable for mobile communications and automotive applications.
The MC68HC711P2 is an EPROM version of the MC68HC11P2, with the User ROM replaced by a similar amount of EPROM. All references to the MC68HC11P2 apply equally to the MC68HC711P2, unless otherwise noted.
MC68HC11P2 Features
Low power, high performance M68HC11 CPU core, with 4MHz bus capability
Power saving PLL clock circuit, with automatic disable during WAIT mode
32kbytes of User ROM (MC68HC11P2); 32kbytes User EPROM (MC68HC711P2)
1kbyte of RAM
640 bytes of byte-erasable User EEPROM, with on-chip charge pump
Up to 50 general purpose I/O lines, plus up to 12 input-only lines
Non-multiplexed address and data buses, permitting direct access to the full 64k address map
16-bit timer with 3/4 input captures and 4/5 output compares;pulse accumulator and COP watchdog timer
Three 8- or 9-bit SCI subsystems, two with MI BUS?capability
SPI subsystem, with software selectable MSB/LSB first option
8-channel, 8-bit analog-to-digital (A/D) converter
Four 8-bit PWM timer channels (may be concatenated to form one, or two, 16-bit channels)
Available in 84-pin PLCC or 84-pin CERQUAD packages
