MCF52259 ColdFire
Microcontroller
®
The MCF52259 is a member of the ColdFire family of
• Two 16-bit periodic interrupt timers (PITs)
reduced instruction set computing (RISC) microprocessors.
• Real-time clock (RTC) module with 32 kHz crystal
• Programmable software watchdog timer
• Secondary watchdog timer with independent clock
• Interrupt controller capable of handling 57 sources
• Clock module with 8 MHz on-chip relaxation oscillator
and integrated phase-locked loop (PLL)
This document provides an overview of the 32-bit MCF52259
microcontroller, focusing on its highly integrated and diverse
feature set.
This 32-bit device is based on the Version 2 ColdFire core
operating at a frequency up to 80 MHz, offering high
performance and low power consumption. On-chip memories
connected tightly to the processor core include up to
512 Kbytes of flash memory and 64 Kbytes of static random
access memory (SRAM). On-chip modules include:
• V2 ColdFire core delivering 76 MIPS (Dhrystone 2.1) at
80 MHz running from internal flash memory with
Enhanced Multiply Accumulate (MAC) Unit and hardware
divider
• Test access/debug port (JTAG, BDM)
• Cryptography Acceleration Unit (CAU)
• Fast Ethernet controller (FEC)
• Mini-FlexBus external bus interface available on 144 pin
packages
• Universal Serial Bus On-The-Go (USBOTG)
• USB Transceiver
• FlexCAN controller area network (CAN) module
• Three universal asynchronous/synchronous
receiver/transmitters (UARTs)
• Two inter-integrated circuit (I2C™) bus interface modules
• Queued serial peripheral interface (QSPI) module
• Eight-channel 12-bit fast analog-to-digital converter
(ADC) with simultaneous sampling
• Four-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
• Eight-channel/Four-channel, 8-bit/16-bit pulse width
modulation timer
