32 / 439 page ![]() 9. Memory Organization There are 2 types of memory in PIC16F152 microcontroller devices: • Program Memory – Program Flash Memory – Configuration Words – Device ID – Revision ID – User ID – Device Information Area (DIA) – Device Configuration Information (DCI) • Data Memory – Core Registers – Special Function Registers (FSR) – General Purpose RAM (GPR) – Common RAM In Harvard architecture devices, the data and program memories use separate buses that allow for concurrent access of the two memory spaces. Additional detailed information on the operation of the Program Flash Memory is provided in the “NVM - Nonvolatile Memory Module” section. 9.1 Program Memory Organization The enhanced mid-range core has a 15-bit Program Counter capable of addressing 32K x 14 program memory space. The table below shows the memory sizes implemented. Accessing a location above these boundaries will cause a wrap-around within the implemented memory space. The Reset vector is at 0000h and the interrupt vector is at 0004h. Refer to the “Interrupts” chapter for more details. Table 9-1.
