The PIC12C5XX is Microchip Technologies’ line of low-cost, high-performance CMOS microcontrollers. It features a range of 8-bit devices that are totally static and rely on EEPROM/EPROM/ROM for storage. It uses a RISC architecture with only 33 single-word, single-cycle instructions. Every instruction only needs one cycle to execute, except for program branches which need two (1 s). The PIC12C5XX outperforms similarly priced competitors by order of magnitude. The high degree of symmetry in the 12-bit wide instructions allows the 8-bit microcontrollers to reduce their code size by a factor of 2:1. A large margin can slash the development cycle because of the instruction set’s simplicity.
Using fewer resources and reducing costs, the PIC12C5XX family of products excels in both areas. A separate reset circuit is not required, thanks to the Power-On Reset (POR) and the Device Reset Timer (DRT). The internal INTRC oscillator mode and the power-saving Low Power oscillator mode are two of four possible oscillator types. The SLEEP mode, Watchdog Timer, and code protection features improve the system’s cost, power, and dependability by preserving battery life. One-time-programmable (OTP) variants of the PIC12C5XX are readily available and inexpensive and may be manufactured in any quantity.
Microchip’s market-leading prices for OTP microcontrollers mean that you, the customer, can fully take advantage of this advantageous technology. With the PIC12C5XX devices, you can find a full-featured macro assembler, software simulator, in-circuit emulator, “C” compiler, fuzzy logic support tools, low-cost development programmer, and full-featured programmer. It’s important to note that all tools are suitable for use on IBM PCs and other similar machines.
The PIC12C5XX family has a wide variety of applications, including but not limited to low-power remote transmitters and receivers, home security systems, and home appliances. With the help of EEPROM data memory technology, calibration factors and security codes can be updated. On the other hand, EPROM data memory technology makes it very easy to adapt already developed application software to particular use cases (transmitter codes, appliance settings, receiver frequencies, etc.).
Because of their small through-hole and surface-mount packaging, these microcontrollers are an excellent choice for use in applications with restricted space. Because of its high level of flexibility, the PIC12C5XX series can be applied in circumstances where the usage of microcontrollers had not been previously considered (for example, timer functions, replacing “glue” logic and PLDs in larger systems, coprocessor applications). This is due to its low cost, low power consumption, outstanding performance, user-friendliness, and versatility in terms of inputs and outputs. It is also very user-friendly.
Various architectural elements often present in RISC microprocessors are responsible for the PIC12C5XX family’s strong performance, which can be attributed to these features. The PIC12C5XX employs a Harvard architecture, which allows program and data access on separate buses. The microcontroller utilizes this architecture. This increases bandwidth compared to the classic von Neumann design, which fetches programs and data on the same bus.
Another benefit of separating program memory from data memory is that it enables instructions to have a size distinct from the standard 8-bit wide data word. Because the opcodes for the instructions are each 12 bits wide, it is possible to have only single-word instructions. A single cycle is all that is required to get a 12-bit instruction from a program memory access bus that is wide enough to accommodate 12 bits. Instruction fetching and processing occur simultaneously in a pipeline with two stages. As a consequence of this, the execution of each instruction (33) only takes one cycle (1 s @ 4MHz), with the exception of program branching. In the following table, each device’s program memory (EPROM), data memory (RAM), ROM memory, and non-volatile memory (EEPROM) are broken down into their respective categories.
It is possible for the PIC12C5XX to address its register files and data memory either directly or indirectly. The program counter is included among the other special function registers that have been mapped in the data memory. Because the instruction set of the PIC12C5XX is highly orthogonal (symmetrical), it can perform any operation on any register using any addressing mode. This opens up a wide range of programming possibilities. Because of its symmetrical design and absence of’special ideal situations,’ programming the PIC12C5XX may be done in a straightforward and effective manner. Also, the learning curve is flattened out to a far greater extent.
The PIC12C5XX has two distinct types of memory: program and data. Any hardware with more code storage than 512 bytes will use a paging mechanism. Page references in the program memory can be accessed by setting a single bit in the STATUS register. The PIC12C509, PIC12C509A, PICCR509A, and PIC12CE519 use a banking system for their data memory register files larger than 32 registers. The File Select Register (FSR) can access a data memory bank.
Like any other register, the I/O register can be read from and written to by the program. The behavior of read instructions is not impacted by the input/output states of an I/O pin (e.g., MOVF GPIO, W). All inputs have a high impedance condition and are classified as inputs when the I/O control registers are initialized on RESET.
To begin a read operation, the R/W bit of the slave address must be set to 1, just like it is for a write operation. Read operations can be divided into three categories: current address read, random read, and sequential read.
Each PIC12C5XX instruction is composed of a 12-bit word separated into an OPCODE that identifies the type of instruction being given and one or more operands that further define the instruction’s operation.
Microchip Technology’s PIC12C508A-04/P microcontroller is a powerful and flexible tool for building any cutting-edge system or circuit. This 8-bit processor’s versatility stems from its adaptability to temperature, clock speed, and memory size.
