The MCF52259 microcontroller family (MCF52252,
MCF52254, MCF52255, MCF52256, MCF52258, and
MCF52259 devices) 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 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
⢠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 (I2Câ¢) 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), pulse-code modulation (PCM), and pulse
accumulation
⢠Eight-channel/Four-channel, 8-bit/16-bit pulse width
modulation timer
⢠Two 16-bit periodic interrupt timers (PITs)
⢠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)
⢠Test access/debug port (JTAG, BDM)
