Freescale expands its 32-bit ColdFire MCU portfolio

Freescale expands its 32-bit ColdFire MCU portfolio to meet the most stringent performance requirements for home appliances and industrial applications. The new MCF51AG128 MCU series offers the best performance and features to enhance the system safety and integrity of applications, including washing machines, dishwashers, refrigerators, microwave ovens, air conditioners, industrial drive systems/pumps, fans/compressors.

With a supply voltage of 2.7V–5.5V, the AG128 MCU operates at processor core speeds up to 50 MHz and includes 128 KB of FLASH Memory and 16 KB of SRAM. Multiple package options, plus new GPIO enhancements, will allow maximum flexibility in layout and production.

This peripheral set is designed for effective control of three-phase motor control applications. It includes two 16-bit FlexTimers, a high-speed analog comparator, dual 16-bit PWM timers, a programmable delay block, and a 24-channel 12-bit ADC with PWM hardware triggering. In addition, it also includes functions that are important for system security and integrity, such as advanced independent clock COP, external watchdog monitoring, and cyclic redundancy check (CRC) engine to provide CLK for applications covered by IEC 60730 regulations. Fault protection and memory content verification.

The unique IP enables AG128 products to achieve system performance optimization and flexibility through DMA and iEvent modules to complete data transactions and interrupt management, thereby alleviating CPU overhead and improving overall performance.

STefano Frattesi, Indesit’s R&D Electronics Division Manager, said, “The MCF51AG128 32-bit MCUs provide an ideal feature set to enable Indesit to accelerate the implementation of innovative control solutions for the next generation of smart home appliances.”
