Freescale Semiconductor Tower System Kit TWR-56F8400 TWR-56F8400-KIT TWR-56F8400-KIT Guia De Informação

The 56F844x/5x/7x family is based on an 56800EX core, which updates the 56800E core. The 56800EX core has all 56800E
core features and adds new enhancements, including:

• 32-bit x 32-bit MUL/MAC operations
• all registers in the Address Generation Unit (AGU) have shadowed registers that effectively reduce the context save/

restore time during exception processing, reducing latency

• bit-reverse address mode supporting Fast Fourier Transform
• new bit manipulation instruction that integrates a Test bitfield and a Set/Clear (BFSC) bitfield into a single instruction

With all existing 32-bit arithmetic operations, the 56800EX core is truly 32-bit compatible.

Devices in the 56F844x/5x/7x family include multiple blocks of on-chip memory:

• Up to 256 KB (128 KW) program flash memory
• Up to 32 KB (16 KW) data flash memory
• Up to 32 KB (16 KW) RAM

Both bulk erasing and erasing in pages are supported.

A full set of programmable peripherals—including eFlexPWMs, ADCs, QSCIs, QSPIs, I2Cs, a FlexCAN, Inter-Module
Crossbars, Quad Timers, a CRC block, DACs, Analog Comparators, and on-chip/off-chip clock sources—supports various
applications. Each peripheral's clock can be independently gated to save power. Any pin in these peripherals can also be used
as General Purpose Input/Outputs (GPIOs).

With numerous, highly integrated peripherals and powerful processing capabilities, the 56F844x/5x/7x family is especially
useful for switched-mode power supplies (SMPSs), advanced motor control (including dual motor control), smart appliances,
uninterruptible power supplies (UPSs), photovoltaic systems, power distribution systems, wireless charging, and advanced
lighting systems.

Switched-mode power
supplies (SMPSs)

• Multi-output digital SMPSs
• Interleaving Power Factor Correction (PFC)
• Multiple phase converters
• LLC DC to DC converters
