Electromagnetic compatibility (EMC) and electromagnetic interference (EMI) are critical concerns for developers designing in 'noisy' environments that contain numerous electrical components in close proximity. To address this design challenge, Freescale has introduced a scalable microcontroller (MCU) family designed to help engineers cut through the noise in large appliance and industrial applications.
The Flexis AC family features 8-bit devices (MC9S08AC128/96/60/48/32) and 32-bit V1 ColdFire MCUs (MCF51AC256/128) designed to provide high EMC/EMI performance and an array of on-chip peripherals to help reduce component count, system complexity and overall system cost.
This new family is a suitable choice for a single-chip motor control and human-machine interface (HMI) solution in white goods applications, such as washing machines, dryers, refrigerators, dish-washers and other major appliances. The product family is also scalable and flexible enough to meet the needs of a wide range of general industrial applications, from factory automation to building control to HVAC systems.
To help enable basic to advanced motor control, the Flexis AC devices feature three time/pulse-width modulators (TPM) on the 8-bit S08AC128/96 devices and an advanced 16-bit FlexTimer module on the 32-bit MCF51AC256/128 ColdFire MCUs designed to simplify the control of complex solutions.
The ColdFire V1 devices offer the performance and peripherals to handle sophisticated motor control algorithms while simultaneously driving touch-screen user interfaces based on Freescale's proximity sensing software. The ColdFire MCUs also feature a controller area network (CAN) bus for network connectivity and the ability to synchronise the analog-to-digital controller (ADC) and the FlexTimer module for motor control.
To enhance system integrity, security and reliability, the MCUs integrate a wide range of hardware and software system protection features. These safety features help manufacturers of automatic controls used in large appliance and industrial equipment comply with key regulations, such as the IEC 60730 class B regulation. Additional features, such as active power-on reset, low voltage detection and low voltage warning, help protect against system failure caused by brownouts.
