Freescale Semiconductor Document Number: MCF52235 Rev. 10, 3/2011 Data Sheet: Technical Data MCF52235 LQFP-80 LQFP-112 MCF52235 ColdFire 14mm x 14mm 20mm x 20mm Microcontroller Data Sheet MAPBGA-121 Supports MCF52230, MCF52231, 12mm x 12mm MCF52232, MCF52233, MCF52234, MCF52235, and MCF52236 The MCF52235 is a member of the ColdFire family of Two 16-bit periodic interrupt timers (PITs) reduced instruction set computing (RISC) microcontrollers. Real-time clock (RTC) module This document provides an overview of the MCF52235 Programmable software watchdog timer microcontroller family, focusing on its highly integrated and Two interrupt controllers providing every peripheral with a diverse feature set. unique selectable-priority interrupt vector plus seven external interrupts with fixed levels/priorities This 32-bit device is based on the Version 2 ColdFire core Clock module with support for crystal or external oscillator operating at a frequency up to 60 MHz, offering high and integrated phase-locked loop (PLL) performance and low power consumption. On-chip memories Test access/debug port (JTAG, BDM) 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) 2 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) Freescale reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.
