56F8025 Description
The 56F8025 supports program execution from internal memories. Two data operands can be accessed
from the on-chip data RAM per instruction cycle. The 56F8025 also offers up to 35 General-Purpose
Input/Output (GPIO) lines, depending on peripheral configuration.
The 56F8025 Digital Signal Controller includes 32KB of Program Flash and 4KB of Unified
Data/Program RAM. Program Flash memory can be independently bulk erased or erased in pages.
Program Flash page erase size is 512 Bytes (256 Words).
A full set of programmable peripherals — PWM, ADCs, QSCI, QSPI, I2C, PIT, Quad Timers, DACs, and
analog comparators — supports various applications. Each peripheral can be independently shut down to
save power. Any pin in these peripherals can also be used as General Purpose Input/Outputs (GPIOs).
