The MCF52235 is a member of the ColdFire

family of

reduced instruction set computing (RISC) microcontrollers.

This document provides an overview of the MCF52235

microcontroller family, 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 60 MHz, offering high

performance and low power consumption. On-chip memories

connected tightly to the processor core include up to 256

Kbytes of Flash and 32 Kbytes of static random access

memory (SRAM). On-chip modules include:

• V2 ColdFire core providing 56 Dhrystone 2.1 MIPS @ 60

MHz executing out of on-chip Flash memory using

enhanced multiply accumulate (EMAC) and hardware

divider

• Enhanced Multiply Accumulate Unit (EMAC) and

hardware divide module

• Cryptographic Acceleration Unit (CAU) coprocessor

• Fast Ethernet Controller (FEC)

• On-chip Ethernet Transceiver (EPHY)

• FlexCAN controller area network (CAN) module

• Three universal asynchronous/synchronous

receiver/transmitters (UARTs)

• Inter-integrated circuit (I

C™) bus controller

• Queued serial peripheral interface (QSPI) module

• Eight-channel 10- or 12-bit fast analog-to-digital converter

(ADC)

• 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/Four-channel 8/16-bit pulse width modulation timers

(two adjacent 8-bit PWMs can be concatenated to form a

single 16-bit timer)

•

LQFP-80

14mm x 14mm

LQFP-112

20mm_x_20mm

MAPBGA-121

12mm_x_12mm

Two 16-bit periodic interrupt timers (PITs)

Real-time clock (RTC) module

Programmable software watchdog timer

Two interrupt controllers providing every peripheral with a

unique selectable-priority interrupt vector plus seven

external interrupts with fixed levels/priorities

• Clock module with support for crystal or external oscillator

and integrated phase-locked loop (PLL)

• Test access/debug port (JTAG, BDM)

Freescale reserves the right to change the detail specifications as may be required to permit

improvements in the design of its products.
