The MCF52235 is a member of the ColdFire^® family of
reduced instruction set computing (RISC)
microprocessors. This hardware specification provides
an overview of the 32-bit MCF52235 microcontroller,
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
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)
