General Description

The MC68HC05L5 is an 80-pin microcontroller unit (MCU) with highly

sophisticated on-chip peripheral functions. The memory map includes

8 Kbytes of user ROM and 256 bytes of static RAM. The MCU has five

parallel ports: A, B, C, D, and E. The MC68HC05L5 includes a timebase

circuit, 8- and 16-bit timers, a computer operating properly (COP)

watchdog timer, liquid crystal display (LCD) drivers, and a simple serial

peripheral interface (SSPI).

Features of the MC68HC05L5 MCU include:

? Low-cost HC05 core

? 8,208 bytes of user ROM and 256 bytes of user static RAM

? General-purpose data pins:

– 14 bidirectional pins

– 10 input/ouptut-only pins

– 15 output-only pins, including 8-bit key wakeup interrupts

? Pullup resistors options

? Open-drain outputs options

? Two interrupt request (IRQ) inputs

? 16-bit timer with input capture and output compare (timer 1)

? 8-bit event counter/modulus clock divider (timer 2)

? Simple serial peripheral interface (SSPI)

? LCD drivers — 1-to-4 backplane drivers x 27-to-39 frontplane

drivers

? On-chip timebase circuits with COP watchdog timer and timebase

interrupts

? Dual oscillators and selectable system clock frequency

? Power-saving stop mode and wait mode

? 80-pin quad flat pack (QFP) package
