MC68302PV25C

The MC68302PV25C is a Pin-Compatible with Legacy MC68302 Integrated Controller for Industrial, Computing and Telecommunications applications. Integrating on-chip RAM and ROM, along with a high speed 25MHz 32-bit CPU core, this device is a highly functional and low cost system controller.

Applications of the MC68302PV25C include industrial automation, telecommunication and office equipment control, robotics control, security systems, telecommunications and imaging systems, portable and mobile systems, instrumentation and embedded motion/media controllers.

The internal architecture of the MC68302PV25C includes an integrated memory system that includes a 32-bit CPU core, on-chip flash program memory, conventional RAM and ROM, plus four communications buses. The MC68302PV25C also provides integrated support for timer or pulse-width modulated I/O and a range of communications functions, further increasing its flexibility and signal processing power.

In addition to its program and data storage capabilities, the MC68302PV25C consists of a small set of user selectable control and peripheral functions. This includes control over the timing and control of system peripherals, setting priorities and limits, as well as providing a low latency interrupt handling method. For pin-compatibility with older versions, the MC68302PV25C additionally features the data bus, address bus and control pins of the legacy MC68302 together with distinct pins for more powerful hardware features.

The MC68302PV25C is run by a single internal clock. This clock can be programmed to an external oscillator or a crystal oscillator with a variable frequency from 8MHz to 32MHz. The clock frequency can be decreased by programming init control registers or by dividing the clock frequency by a programmable number between 0 and 64. A watchdog timer is also provided which monitors the state of the CPU and can reset it if it becomes unresponsive due to software malfunction. The watchdog timer can also be used in real time system applications like digital audio systems.

For communication, a Programmable ThisBus (PTB) is included which allows a range of register programmable communications devices such as UARTs, I2C, SPI, and other digital data acquisition systems. It also provides a wide range of pin configurations and timing characteristics that allow control of a variety of communication systems. Additionally, the MC68302PV25C supports a low latency priority interrupt function, which is useful for real time system tasks. Furthermore, it provides a wide range of interrupt sources including external interrupts, analog-digital converters and other communication interface devices.

In summary, the MC68302PV25C is a large, powerful and low cost system controller for various applications. It contains an integrated memory array and numerous communications buses, with a programmable oscillator for variable frequency and a watchdog timer for improved system performance. Additionally, it features high speed 32-bit CPU core, along with support for pin-compatibility with legacy versions. The MC68302PV25C additionally provides an extensive selection of control and peripheral functions, and a range of digital signal processing and timing functions to improve system performance.
