The first 32 bytes of the register space are allocated to special-purpose registers; the remaining 96 bytes are used for general-purpose RAM.

In contrast, in the PIC18 series, the program memory is addressed in 8-bit increments byteswhich differs from the instruction width of 16 bits. The following stack limitations have been addressed in the PIC18 series, but still apply to earlier cores:.

Retrieved 18 April The high half of odd words reads as zero.

Retrieved 23 October Note that a CALL instruction only includes 8 bits of address, and may pi16f873 specify addresses in the first half of each word page. The 17 series is not recommended for new designs, and availability may be limited to users. Baseline devices are available in 6-pin to pin packages. PIC devices are popular with both industrial developers and hobbyists due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost or free development tools, serial programming, and re-programmable Flash-memory capability.

Pi1c6f873 are Microchip’s first inherently bit microcontrollers.

Retrieved from ” https: Wikibooks has a book on the topic of: Some of these debug chips are able to operate as more than one type of chip by the use of selectable jumpers on the daughter board. It is currently discontinued.

Special-purpose control registers for on-chip hardware resources are also mapped into the data space. The architectural decisions are directed at the maximization of speed-to-cost ratio.

PIC microcontrollers

Because cores before PIC18 had only unconditional branch instructions, conditional jumps are implemented by a conditional skip with the opposite condition followed by an unconditional branch. InMicrochip introduced the dsPIC series of chips, [10] which entered mass production in late To load a constant, it is necessary to load it into W before it can be moved into another register.

The program counter is 23 bits wide, but the least significant bit is always 0, so there are 22 modifiable bits. This register must be changed every time control transfers between pages. There are a few additional miscellaneous instructions, and two additional 8-bit literal instructions, add and subtract.

PIC17 devices were produced in packages from 40 to 68 pins. There is no distinction between memory space and register space because the RAM serves the job of both memory and registers, and the RAM is usually just referred to as the register file or simply as the registers. Many ultra-low-cost OTP microcontrollers from Asian manufacturers, found in low-cost consumer electronics are based on the PIC architecture or modified form.

Retrieved 23 September Instruction ROM is 24 bits wide. Improvements over earlier cores are bit wide opcodes allowing many new instructionsand a level deep call stack. To debug these devices, a special -ICD version of the chip mounted on a daughter board which provides dedicated ports is required.

On the older cores, all register moves needed to pass through W, but this changed on the “high-end” cores. The hardware stack is not software-accessible on earlier devices, but this changed with the 18 series devices. External data memory is not directly addressable except in some PIC18 devices with high pin count.

Today, a huge variety of PICs are available with various on-board peripherals serial communication modules, UARTsmotor control kernels, etc. The binary representations of the machine instructions vary by family and are shown in PIC instruction listings. The PIC instruction set is suited to implementation of fast lookup tables in the program space. The instruction set differs very little from the baseline devices, but the two additional opcode bits allow registers and words of code to be directly addressed.

Retrieved 7 April In general, there is no provision for storing code in external memory due to the lack of an external memory interface. Program memory and data memory are separated. Many of these complex programmers use a pre-programmed PIC themselves to send the programming commands to the PIC that is to be programmed.
