Electromagnetic compatibility (EMC) and electromagnetic interference (EMI) are major concerns for developers designing in "noisy" environments, covering many electrical components that are close to sensing. To address this design challenge, Freescale has introduced a family of scalable microcontrollers (MCUs) to help engineers reduce noise in large and industrial applications.
Freescale's semi-Flexis AC family features 8-bit devices (MC9S08AC128/96/60/48/32) and 32-bit V1ColdFireMCUs (MCF51AC256/128) designed to deliver outstanding EMC/EMI performance and a variety of on-chip peripherals to help reduce The number of components reduces system complexity and total system cost. As the third member of Freescale's Flexis family of 8- to 32-pin, peripheral and software-compatible MCU families, the AC Series offers an upward migration path from the existing Freescale 8-bit MC9S08AW.
The ideal solution for large appliances and industrial controls
The FlexisAC Series is the best choice for single control and human machine interface (HMI) solutions for white goods applications such as washing machines, dryers, refrigerators, dishwashers and other appliances. The product range is also extremely scalable and flexible to meet the needs of a variety of common industrial applications including factory automation, building control and HVAC systems.
The outstanding EMC/EMI performance of Flexis AC devices at 5V allows designers to reduce the number of external components required for these applications, creating a cost-effective electromagnetic mute system.
Intelligent peripherals for high performance and cost reduction
To help achieve basic to advanced motor control, the FlexisAC device features a three-time/pulse width modulator (TPM) on an 8-bit S08AC128/96 device and an advanced 16-bit FlexTimer module on a 32-bit MCF51AC256/128 ColdFireMCU. Control of complex solutions.
The ColdFire V1 device provides performance and peripherals to handle advanced motor control algorithms while relying on Freescale's proximity sensing software to drive the touch screen user interface. As a result, developers need only a 32-bit FlexisMCU to drive the entire appliance application while helping to reduce component count, system cost and time to market. The ColdFire MCU also features a Controller Area Network (CAN) bus feature that supports network connectivity and enables simultaneous analog-to-digital (ADC) and FlexTimer modules for state-of-the-art motor control.
To improve system integrity, security and reliability, Flexis ACMCU integrates a wide range of hardware and software system protection features. These safety features help manufacturers of automatic control equipment used in large power and industrial equipment comply with regulations such as IEC 60730 Class B for safe and reliable operation of household appliances. Features such as active power-on reset, detection, and low-voltage alarms can help prevent system failures caused by power outages. This on-chip feature makes the FlexisAC family one of the most powerful MCU products.

Freescale offers a comprehensive support and training ecosystem of development tools, reference designs, application notes, software examples and webcasts. To help developers get their boards up and running faster, Freescale introduced DEMOACKIT, a flexible, cost-effective evaluation system for the FlexisAC family. DEMOACKIT includes 8-bit and 32-bit Flexis AC daughter cards with built-in USBBDM, serial interface, acceleration and I/O headers.
Freescale also introduced the DEMOACEX expansion board, which plugs into DEMOACKIT, allowing developers to take advantage of other performance and integration features, such as CAN from 32-bit solutions.
The Flexis AC MCU is supported by a complimentary version of CodeWarrior Dev el opmentStudio for the 6.1 version of the microcontroller, which supports software development for Freescale's 8-bit or 32-bit MCUs. Designers can further accelerate application development with the award-winning rapid application development tool ProcessorExpert tool in the CodeWarrior tool suite.

A car MP3 player, also called as car stereo mp3, is an electronic device that is designed to play digital audio files in a car. Car MP3 players are a popular accessory for car owners who want to listen to their favorite music while driving, thus it is known as car music player. It is a portable device that can be connected to a car's audio system through a USB cable or Bluetooth. They often have a display screen that shows the track name, artist, and album information. The player can read digital audio files from a USB flash drive, SD or TF card, or other storage devices. Except FM radio tuners, some car MP3 players also have DAB functions and can play audio from CDs and DVDs.
