MICROCHIP DSPIC30F6014A-30I/PT Digital Signal Controller, dsPIC30F Series, 40 MHz, 144 KB, 68 I/O's, CAN, I2C, SPI, UART, 5.5 V

The DSPIC30F6014A-30I/PT is a 16-bit high-performance Digital Signal Controller feature high-performance modified RISC CPU. The program counter (PC) is 23-bits wide with the least significant bit (LSb) always clear and the most significant bit (MSb) is ignored during normal program execution, except for certain specialized instructions. Thus, the PC can address up to 4M instruction words of user program space. An instruction prefetch mechanism is used to help maintain throughput. Program loop constructs, free from loop count management overhead, are supported using the DO and REPEAT instructions, both of which are interruptible at any point. The working register array consists of 16 x 16-bit registers, each of which can act as data, address or offset registers. One working register (W15) operates as a software stack pointer for interrupts and calls. The data space is 64Kbytes (32K words) and is split into two blocks, referred to as X and Y data memory.
