General Description
1.2 Introduction
The MC68HC908LJ24 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.
1.3 Features
Data Sheet

Features of the MC68HC908LJ24 include the following:
⢠High-performance M68HC08 architecture
⢠Fully upward-compatible object code with M6805, M146805, and
M68HC05 Families
â 8-MHz at 5V operating voltage
â 4-MHz at 3.3V operating voltage
⢠32.768kHz crystal oscillator clock input with 32MHz internal PLL
⢠Optional continuous crystal oscillator operation in stop mode
⢠24K-bytes user program FLASH memory with security1 feature
⢠768 bytes of on-chip RAM
⢠Up to 48 general-purpose input/output (I/O) pins:
â High current 15mA sink capability on 30 pins
⢠Two 16-bit, 2-channel timer interface modules (TIM1 and TIM2)
with selectable input capture, output compare, PWM capability on
each channel, and external clock input option (T1CLK and T2CLK)
⢠Real time clock (RTC) with:
â Clock, calendar, alarm, and chronograph functions
â Selectable periodic interrupt requests for seconds, minutes,
hours, days, 2-Hz, 4-Hz, 8-Hz, 16-Hz, and 128-Hz
1. No security feature is absolutely secure. However, Motorola strategy is to make reading or
copying the FLASH difficult for unauthorized users.
