| The **MBHP Core Module is the heart and brain of every MIDIbox**. It holds the //PIC microcontroller// which runs [[MIOS]] and your MIDIbox application. It handles **//MIDI communication, it drives an LCD (or two), and it connects to all the other modules//**. | The **MBHP Core8 Module is the Original heart and brain of every MIDIbox**.

| The PIC is a **“system on chip” (SoC)**, this means, it contains not only a CPU, but also an **//integrated 32k flash program memory, 1536 bytes data memory, 256 bytes data EEPROM, and a lot of usefull peripherals like AD-converter and UART (for MIDI)//**. The low prices and worldwide availability for hobbyists makes it a good choice. | The PIC is a **“System On Chip” (SoC)**, this means, it contains not only a CPU, but also an **//integrated 32k flash program memory, 1536 bytes data memory, 256 bytes data EEPROM, and a lot of usefull peripherals like AD-converter and UART (for MIDI)//**.

| If you are planning to program your own application, it's recommended to use a PIC18F452 for highest compatibility with existing MIDIboxes, a **PIC18F4620 for RAM intensive projects** (64k flash, 1k EEPROM, 3968 bytes RAM), or a **PIC18F4685 for code intensive projects** (96k flash, 1k EEPROM, but only 3328 bytes RAM - provides CAN interface | If you are planning to program your own application, it's recommended to use a PIC18F452 for highest compatibility with existing MIDIboxes, a **PIC18F4620 for RAM intensive projects** (64k flash, 1k EEPROM, 3968 bytes RAM), or a **PIC18F4685 for code intensive projects** (96k flash, 1k EEPROM, but only 3328 bytes RAM - provides CAN interface |
