S9S12G48F1MLC

16位微控制器 - MCU 16-bit MCU S12 core 48KB Flash 25MHz

S12 16-Bit Central Processor Unit (CPU) S9S12G48F1MLC

S12 CPU is a high-speed 16-bit processing unit:

• Full 16-bit data paths supports efficient arithmetic operation and high-speed math execution

• Includes many single-byte instructions. This allows much more efficient use of ROM space.

• Extensive set of indexed addressing capabilities, including:

— Using the stack pointer as an indexing register in all indexed operations

— Using the program counter as an indexing register in all but auto increment/decrement mode

— Accumulator offsets using A, B, or D accumulators

— Automatic index predecrement, preincrement, postdecrement, and postincrement (by –8 to +8)

Main External Oscillator (XOSCLCP) S9S12G48F1MLC

• Loop control Pierce oscillator using a 4 MHz to 16 MHz crystal

— Current gain control on amplitude output

— Signal with low harmonic distortion

— Low power

— Good noise immunity

— Eliminates need for external current limiting resistor

— Transconductance sized for optimum start-up margin for typical crystals

— Oscillator pins can be shared w/ GPIO functionality
