MCU 16-bit dSPIC33 dsPIC RISC 128KB Flash 3.3V 100-Pin TQFP Tray
- Program Flash Memory (Kbytes): 128
- RAM (Bytes): 16
- Number of pins: 100
- Modified Harvard architecture
- C compiler optimized instruction set
- 16-bit wide data path
- 24-bit wide instructions
- Linear program memory addressing up to 4M instruction words
- Linear data memory addressing up to 64 Kbytes
- 83 base instructions: mostly 1 word/1 cycle
- Sixteen 16-bit General Purpose Registers
- Two 40-bit accumulators:
- With rounding and saturation options
- Flexible and powerful addressing modes:
- Indirect, Modulo and Bit-Reversed
- Software stack
- 16 x 16 fractional/integer multiply operations
- 32/16 and 16/16 divide operations
- Single-cycle multiply and accumulate:
- Accumulator write back for DSP operations
- Dual data fetch
- Up to ±16-bit shifts for up to 40-bit data
- 8-channel hardware DMA
- 2 Kbytes dual ported DMA buffer area (DMA RAM) to store data transferred via DMA:
- Allows data transfer between RAM and a peripheral while CPU is executing code (no cycle stealing)
- Most peripherals support DMA
- On-chip 2.5V voltage regulator
- Switch between clock sources in real time
- Idle, Sleep and Doze modes with fast wake-up
