MCF52254AF80 Datasheet PDF - NXP

●The MCF52254AF80 is a 32-bit Microcontroller based on the Version 2 ColdFire core operating at a frequency up to 80MHz, offering high performance and low power consumption. On-chip memories connected tightly to the processor core include up to 512kB of flash memory and 64kB of static random access memory (SRAM). It features 4-channel general-purpose timer (GPT) capable of input capture/output compare, pulse width modulation and clock module with 8MHz on-chip relaxation oscillator and integrated phase-locked loop (PLL).

● Static operation

● 16 General-purpose, 32-bit data and address registers

● Cryptographic acceleration unit (CAU)

● Tightly-coupled coprocessor to accelerate software-based encryption and message digest functions

● System debug support - Background debug mode (BDM) for in-circuit debugging

● Real-time trace for determining dynamic execution path

● On-chip memories - Up to 512KB of interleaved flash memory supporting 2-1-1-1 accesses

● Fully static operation with processor sleep and whole chip stop modes

● Rapid response to interrupts from the low-power sleep mode

● Clock enable/disable for each peripheral when not used

● Software controlled disable of external clock output for low-power consumption

● Based on and includes all existing features of the TouCAN module

● Full implementation of the CAN protocol specification version 2.0B

● Zero to eight bytes data length

● Unused MB space can be used as general purpose RAM space

● Listen-only mode capability

● Content-related addressing

● No read/write semaphores

● Time stamp based on 16-bit free-running timer

● Global network time, synchronized by a specific message
