Introduction

Peripheral Interface Controller is one of the advanced micro controllers developed by microchip technologies. These microcontrollers are widely used in modern electronic applications. A PIC controller integrates all type of advanced interfacing ports and memory modules. These controllers are more advanced than normal microcontrollers like INTEL 8051. The first PIC chip was announced in 1975 (PIC1650). As like normal microcontroller, the PIC chip also combines a microprocessor unit called CPU and is integrated with various types of memory modules (RAM, ROM, EEPROM, etc), I/O Ports, timers/counters, communication ports etc.

Limitations of PIC Architecture

Peripheral Interface Controller has only one accumulator. Small Instruction set Register Banking switch required to access RAM of other devices. Operations and registers are not orthogonal. Program memory is not accessible.

Advantages of PIC

Reliability- The PIC-controlled system often resides in machines that are
expected to run continuously for many years without any error and in some
cases recover by themselves if an error occurs (with help of supporting
firmware).

Performance- Many of PIC-based embedded systems use a simple pipeline
RISC processor for computation and most of them provide on-chip SRAM
for data storage to improve performance.

Power Consumption- A PIC control system operates with minimal power
consumption without sacrificing performance. Power consumption can be
reduced by independently and dynamically controlling multiple power
platforms.

Memory- Most of the PIC-based Systems are memory expendable and will
help in easily adding more and more memory according to the usage and
type of application. In small applications, the inbuilt memory can be used.

 

Note: Peripheral Micro Controllers serves a very specific function of controlling
electronic automation with a consummate budget in contrast with a microprocessor that only maintains the general processing function of CPU in a costly operation.
