1/5/10Pcs Microchip PIC16F628-20I/SS FLASH-Based 8-Bit CMOS Microcontroller SSOP-20
The PIC16F62X can directly or indirectly address its register files or data memory. All Special Function registers, including the program counter, are mapped in the data memory. The PIC16F62X have an orthogonal (symmetrical) instruction set that makes it possible to carry out any operation, on any register, using any Addressing mode. This symmetrical nature, and lack of ‘special optimal situations’ make programming with the PIC16F62X simple yet efficient. In addition, the learning curve is reduced significantly. The PIC16F62X devices contain an 8-bit ALU and working register. The ALU is a general purpose arithmetic unit. It performs arithmetic and Boolean functions between data in the working register and any register file.  The ALU is 8-bit wide and capable of addition, subtraction, shift and logical operations. Unless otherwise mentioned, arithmetic operations are two's complement in nature. In two-operand instructions, typically one operand is the working register (W register). The other operand is a file register or an immediate constant. In single operand instructions, the operand is either the W register or a file register. The W register is an 8-bit working register used for ALU operations. It is not an addressable register. Depending on the instruction executed, the ALU may affect the values of the Carry (C), Digit Carry (DC), and Zero (Z) bits in the STATUS register. The C and DC bits operate as a Borrow and Digit Borrow out bit, respectively, bit in subtraction. See the SUBLW and SUBWF instructions for examples. A simplified block diagram is shown in Figure 2-1, and a description of the device pins in Table 2-1. Two types of data memory are provided on the PIC16F62X devices. Non-volatile EEPROM data memory is provided for long term storage of data such as calibration values, lookup table data, and any other data which may require periodic updating in the field. This data is not lost when power is removed. The other data memory provided is regular RAM data memory. Regular RAM data memory is provided for temporary storage of data during normal operation. It is lost when power is removed.
