dsPIC33FJ128GPX02/X04

High-Performance, 16-Bit Digital Signal Controllers

Operating Range:

• Up to 40 MIPS operation (at 3.0-3.6V):

- Industrial temperature range (-40°C to +85°C)

- Extended temperature range (-40°C to +125°C)

• Up to 20 MIPS operation (at 3.0-3.6V):

- High temperature range (-40°C to +140°C)

High-Performance DSC CPU:

• 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

• Two 40-bit accumulators with rounding and

saturation options

• Flexible and powerful addressing modes:

- Indirect

- Modulo

- 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

Direct Memory Access (DMA):

• 8-channel hardware DMA

• Up to 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

Timers/Capture/Compare/PWM:

• Timer/Counters, up to five 16-bit timers:

- Can pair up to make two 32-bit timers

- One timer runs as a Real-Time Clock with an

external 32.768 kHz oscillator

- Programmable prescaler

• Input Capture (up to four channels):

- Capture on up, down or both edges

- 16-bit capture input functions

- 4-deep FIFO on each capture

• Output Compare (up to four channels):

- Single or Dual 16-bit Compare mode

- 16-bit Glitchless PWM mode

• Hardware Real-Time Clock/Calendar (RTCC):

- Provides clock, calendar and alarm functions

Interrupt Controller:

• 5-cycle latency

• Up to 49 available interrupt sources

• Up to three external interrupts

• Seven programmable priority levels

• Five processor exceptions

Digital I/O:

• Peripheral pin Select functionality

• Up to 35 programmable digital I/O pins

• Wake-up/Interrupt-on-Change for up to 31 pins

• Output pins can drive from 3.0V to 3.6V

• Up to 5V output with open drain configuration

• All digital input pins are 5V tolerant

• 4 mA sink on all I/O pins

On-Chip Flash and SRAM:

• Flash program memory (up to 128 Kbytes)

• Data SRAM (up to 16 Kbytes)

• Boot, Secure and General Security for program

Flash
