The MCF52259 is a member of the ColdFire® family of Reduced Instruction Set Computing (RISC) microprocessors.
This document provides an overview of the 32-bit MCF52259 microcontroller, focusing on its high integration and diverse feature set.
This 32-bit device is based on a version 2 ColdFire core operating at up to 80 MHz for performance and low power consumption.
On-chip memory is tightly coupled to the processor core, including 512 KB of flash memory and 64 KB of static random-access memory (SRAM).
On-chip modules include: • V2 ColdFire core delivering 76 MIPS (Dhrystone 2.1) 80 MHz, running from internal flash with enhanced multiply-accumulate (MAC) unit and hardware divider, divider
• Crypto Acceleration Unit (CAU)
• Fast Ethernet Controller (FEC)
• Micro FlexBus external bus interface available in 144-pin package
• Universal Serial Bus on the Go (USBOTG)
• USB transceiver
• FlexCAN Controller Area Network (CAN) module
• Three universal asynchronous/synchronous receivers/transmitters
• Two Inter-Integrated Circuit (I2C™) bus interface modules
• Queued Serial Peripheral Interface (QSPI) module
• Eight-channel 12-bit fast analog-to-digital converter (ADC), simultaneous sampling
• Quad Channel Direct Memory Access (DMA) Controller
• Four 32-bit input capture/output compare timers with DMA support (DTIM)
• Four-channel general purpose timer (GPT) capable of input capture/output compare, pulse width modulation (PWM) and pulse accumulation
• Octal/Quad Channel, 8-bit/16-bit PWM Timer Two 16-bit Periodic Interrupt Timers (PIT)
• Real Time Clock (RTC) module with 32 kHz crystal
• Programmable software watchdog timer
• Auxiliary watchdog timer with independent clock
• Interrupt controller capable of handling 57 sources
