The MCF51AG family expands Freescale's 32-bit ColdFire microcontroller portfolio by offering products with direct memory access (DMA) and iEvent modules to handle data transaction and interrupt management, off-loading CPU overhead and increasing overall performance. The device family targets smart appliance and industrial applications with a peripheral set aligned to the needs of its advanced three-phase motor control to improve the overall energy efficiency of the application. Also included is functionality for system safety and integrity, such as an advanced independently clocked COP, external watchdog monitor and a cyclic redundancy check (CRC) engine providing failure protection and memory content validation for applications covered by IEC regulations.ColdFire V1 core delivering a 50 MHz core speed and 25 MHz bus speed4-channel DMA with selectable peripheral sourcesiEvent module for peripheral-to-peripheral triggering with no CPU interventionUp to 128 KB flash and 16 KB SRAM2 x 6-channel 16-bit FlexTimer modules for motor control24-channel 12-bit analog-to-digital converter (ADC) with pulse width modulated hardware triggering2 high-speed analog comparators with integrated DACCommunication peripherals: 2 x serial peripheral interface (SPI), 2 x serial communications interface (SCI) and 1 x I²CAccurate low-cost internal clock sourceAdvanced indepently clocked watchdog for system safety
