Specific Absorption Rate (IEEE)

Your model wireless phone meets the governmental requirements for exposure to radio waves.

Your mobile device is a radio transmitter and receiver. It is designed and manufactured to not exceed limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S. Government and by the Canadian regulatory authorities. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed for the safety of all persons, regardless of age or health, and to account for any variations in measurements.

The exposure standard for mobile devices employs a unit of measurement known as the Specific Absorption Rate (SAR). The IEEE SAR limit set by the FCC and by the Canadian regulatory authorities is

1.6watts per kilogram (W/kg), averaged over one gram of tissue. Tests for SAR are conducted using procedures accepted by the FCC and by Industry Canada with the mobile device transmitting at its highest certified power level in all tested frequencies. Although the SAR is determined at the highest certified power level, the actual SAR level of the mobile device while operating can be below the maximum value. This is because the mobile device is designed to operate at multiple power levels so as to use only the power required to reach the network.

In general, the closer you are to a wireless base station, the lower the power output.

Before a mobile device is available for sale to the public in the U.S. and Canada, it must be tested and certified to the FCC and Industry Canada that it does not exceed the limit established by each government for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) submitted to the FCC and available for review by Industry Canada. The highest SAR value for this mobile device when tested for use at the ear is 0.61 W/kg, and when worn on the body, as described in this guide, is 0.79 W/kg. The SAR value for this mobile device in its data transmission mode (body-worn use) is

0.33W/kg. Body-worn measurements can differ, depending upon available accessories and regulatory requirements. The SAR information includes the Motorola testing protocol, assessment procedure, and measurement uncertainty range for this product.

While there may be differences between the SAR levels of various mobile devices and at various positions, they meet the governmental requirements for safe exposure. Please note that improvements to this product model could cause differences in the SAR value for later products; in all cases, products are designed to be within the guidelines.

68000202467-A specifications

The Motorola 68000 series microprocessor, specifically the 68000202467-A, stands out as a significant piece of technology in the evolution of computing. Launched in the late 1970s and gaining popularity in the 1980s, the Motorola 68000 series paved the way for many modern computing technologies. The 68000202467-A variant is known for its robust features that range from high computational efficiency to extensive compatibility with various systems.

One of the key characteristics of the 68000202467-A is its 32-bit architecture, which allows for a substantial amount of data processing per cycle compared to its predecessors. With a 16-bit data bus, the processor can interact efficiently with peripherals while maintaining compatibility with older systems. This dual feature of supporting both 16-bit and 32-bit operations made it appealing for a wide array of embedded applications and personal computers.

In terms of performance, the 68000202467-A operates at clock speeds that can reach up to 16 MHz. This speed, combined with a sophisticated instruction set, enables it to handle multiple tasks simultaneously, making it well-suited for multitasking operating systems. The 68000 has a large number of operational modes, which enhance its versatility for software developers.

The Motorola 68000 series also incorporates advanced technologies such as a 7-stage instruction pipeline, which contributes to processing efficiency. This pipelining allows subsequent instructions to be fetched while the current instruction is being executed, minimizing idle CPU time and maximizing throughput. Additionally, the processor supports various addressing modes, making it flexible for programmers to access data in memory.

Another notable aspect of the 68000202467-A is its built-in support for a vast range of development environments. With numerous software development kits and libraries available, developers could easily create applications tailored for both graphics and processing-intensive tasks. This capability turned the 68000 into a preferred choice for the gaming industry during its peak.

Overall, the Motorola 68000202467-A remains a pivotal component in the legacy of microprocessors. Its combination of architectural sophistication, performance capabilities, and compatibility positions it as a landmark in the journey of computing innovation. As technology continues to evolve, the contributions of the 68000 series are still acknowledged and studied, reminding us of how far we have come in microprocessor design and functionality.
