Freescale expands 32bit ColdFire mcu range

The new MCF51AG128 mcu range is said to offer optimal performance and features to enhance system safety and integrity for applications such as washing machines, industrial drives/pumps and fans/compressors. The mcu's have been designed to operate at processor core speeds up to 50MHz across a 2.7 to 5.5V power supply and include 128KB of flash memory, as well as 16KB of SRAM. Multiple package options, combined with new enhanced GPIO functionality, are said to provide maximum flexibility in layout and manufacturing. The peripheral has been designed for efficient control of 3 phase motor control applications and includes two 16bit FlexTimers, high speed analogue comparators, a two channel 16bit PWM timer, a programmable delay block and a 24channel, 12bit ADC with PWM hardware triggering. Also said to be included are an advanced independently clocked COP, external watchdog monitor and a cyclic redundancy check (CRC) engine providing CLK failure protection and memory content validation for applications covered by regulations such as IEC60730. A unique IP is said to enable the AG128 products to optimise system performance and provide flexibility with DMA and iEvent modules, to handle data transaction and interrupt management, thereby offloading cpu overheads and increasing overall performance.
