Overview
This chapter provides an overview of the major features and functional components of the MCF52211
family of microcontrollers. The MCF52211 family is a highly integrated implementation of the ColdFire
®
family of reduced instruction set computing (RISC) microcontrollers that also includes the MCF52210,
MCF52212, and MCF52213. The differences between these parts are summarized in
document is written from the perspective of the MCF52211.
The MCF52211 represents a family of highly-integrated 32-bit microcontrollers based on the V2 ColdFire
microarchitecture. Featuring up to 16 Kbytes of internal SRAM and up to 128 Kbytes of flash memory,
four 32-bit timers with DMA request capability, a 4-channel DMA controller, two I
2
C™ modules, up to 3
UARTs and a queued SPI, the MCF52211 family has been designed for general-purpose industrial control
applications.
This 32-bit device is based on the Version 2 (V2) ColdFire reduced instruction set computing (RISC) core
with a multiply-accumulate unit (MAC) and divider providing 76 Dhrystone 2.1 MIPS at a frequency up
to 80 MHz from internal flash. On-chip modules include the following:
•
V2 ColdFire core with multiply-accumulate unit (MAC)
•
Up to 16 Kbytes of internal SRAM
•
Up to 128 Kbytes of on-chip flash memory
•
Universal Serial Bus On-The-Go (USB OTG) full speed/low speed host and device controller
•
Up to three universal asynchronous receiver/transmitters (UARTs)
•
Two inter-integrated circuit (I
2
C) bus controllers
•
12-bit analog-to-digital converter (ADC)
•
Real-time clock
•
Queued serial peripheral interface (QSPI) module
•
Four-channel, 32-bit direct memory access (DMA) controller
•
Four-channel, 32-bit general purpose timers with optional DMA support
•
Two 16-bit periodic interrupt timers (PITs)
•
Programmable software watchdog timer
•
Backup watchdog timer
•
Interrupt controller capable of handling up to 63 interrupt sources
•
Clock module with 8 MHz on-chip relaxation oscillator and integrated phase-locked loop (PLL)
