Overview
This chapter provides an overview of the major features and functional components of the MCF52110
family of microcontrollers. The MCF52110 family is a highly integrated implementation of the ColdFire
®
family of reduced instruction set computing (RISC) microcontrollers that also includes the MCF52100.
The differences between these parts are summarized in
. This document is written from the
perspective of the MCF52110.
The MCF52110 represents a family of highly-integrated 32-bit microcontrollers based on the V2 ColdFire
microarchitecture. Featuring 16 Kbytes of internal SRAM and 128 Kbytes of flash memory, four 32-bit
timers with DMA request capability, a 4-channel DMA controller, two I
2
C™ modules, 3 UARTs and a
queued SPI, the MCF52110 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)
•
16 Kbytes of internal SRAM
•
128 Kbytes of on-chip flash memory
•
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)
