General Description
1.1 Introduction
The MC68HC908LB8 is a member of the low-cost, high-performance M68HC08 Family of 8-bit
microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit
(CPU08) and are available with a variety of modules, memory sizes, memory types, and package types.
The MC68HC908LB8 has peripherals dedicated to high resolution PWM and power factor correction
(PFC).
1.2 Features
For convenience, features have been organized to reflect:
1.2.1 Standard Features of the MC68HC908LB8
Features of the MC68HC908LB8 include:
1. No security feature is absolutely secure. However, Freescale Semiconductor’s strategy is to make reading or copying the
Freescale Semiconductor
FLASH difficult for unauthorized users.
Standard features of the MC68HC908LB8
Features of the CPU08
8-MHz internal bus frequency
Trimmable internal oscillator:
8 Kbytes of 10 K write/erase cycle typical on-chip in application programmable FLASH memory
with security option
128 bytes of on-chip random-access memory (RAM)
Dual channel high resolution PWM with dead time insertion and shutdown input. The outputs use
frequency dithering to achieve a 4 ns output resolution.
Dual channel pulse-width modulator (PWM) module to provide power factor correction capability
Seven channel, 8-bit successive approximation analog-to-digital converter (ADC)
Op amp/comparator for power factor correction capability or general purpose use
7-bit keyboard interrupt
One 16-bit, 2-channel timer interface module with one output available on port pin (PTA6) for input
capture and PWM
17 general-purpose input/output (I/O) pins and one input only pin
4.0 MHz internal bus operation
8-bit trim capability
25% untrimmed
5% trimmed
Three shared with high resolution PWM (HRP)
Three shared with PWM module
