1.3 System Overview
Figure 1-1. System Overview
The system consists of three functional devices, a wireless optical
mouse using the MC68HC908JB8 (hereafter referred as JB8, production
version uses the low voltage MC68HC08JT8), a wireless multimedia
keyboard using the MC68HC908LK24 (hereafter referred as LK24), and
the wireless receiver using the MC68HC908JB16 (hereafter referred as
JB16).
The basic structure and functional blocks for each device are similar and
consist of a RF transceiver module for half duplex transmission in
2.4-GHz frequency band, a baseband IC for link layer access control and
protocol handling. The overall system operation, I/O interface, and
power management are controlled by MCU.
Based on the number of I/O pins, voltage operation, and memory size
requirements, the JB8 and LK24 are chosen for wireless mouse and
SPI bus
