10 / 330 page PIC24FJ256GA110 FAMILY DS39905E-page 10 2010 Microchip Technology Inc. 1.2 Other Special Features • Peripheral Pin Select: The Peripheral Pin Select (PPS) feature allows most digital peripherals to be mapped over a fixed set of digital I/O pins. Users may independently map the input and/or output of any one of the many digital peripherals to any one of the I/O pins. • Communications: The PIC24FJ256GA110 family incorporates a range of serial communication peripherals to handle a range of application requirements. There are three independent I2C™ modules that support both Master and Slave modes of operation. Devices also have, through the Peripheral Pin Select (PPS) feature, four independent UARTs with built-in IrDA® encoder/decoders and three SPI modules. • Analog Features: All members of the PIC24FJ256GA110 family include a 10-bit A/D Converter module and a triple comparator module. The A/D module incorporates program- mable acquisition time, allowing for a channel to be selected and a conversion to be initiated with- out waiting for a sampling period, as well as faster sampling speeds. The comparator module includes three analog comparators that are configurable for a wide range of operations. • CTMU Interface: In addition to their other analog features, members of the PIC24FJ256GA110 family include the brand new CTMU interface module. This provides a convenient method for precision time measurement and pulse genera- tion, and can serve as an interface for capacitive sensors. • Parallel Master Port: One of the general purpose I/O ports can be reconfigured for enhanced parallel data communications. In this mode, the port can be configured for both master and slave operations, and supports 8-bit transfers with up to 16 external address lines in Master modes. • Real-Time Clock/Calendar: This module implements a full-featured clock and calendar with alarm functions in hardware, freeing up the timer resources and program memory space for the use of the core application. 1.3 Details on Individual Family Members Devices in the PIC24FJ256GA110 family are available in 64-pin, 80-pin and 100-pin packages. The general block diagram for all devices is shown in Figure 1-1. The devices are differentiated from each other in four ways: 1. Flash program memory (64 Kbytes for PIC24FJ64GA1 devices, 128 Kbytes for PIC24FJ128GA1 devices, 192 Kbytes for PIC24FJ192GA1 devices and 256 Kbytes for PIC24FJ256GA1 devices). 2. Available I/O pins and ports (53 pins on 6 ports for 64-pin devices, 69 pins on 7 ports for 80-pin devices and 85 pins on 7 ports for 100-pin devices). 3. Available Interrupt-on-Change Notification (ICN) inputs (same as the number of available I/O pins for all devices). 4. Available remappable pins (31 pins on 64-pin devices, 42 pins on 80-pin devices and 46 pins on 100-pin devices) All other features for devices in this family are identical. These are summarized in Table 1-1. A list of the pin features available on the PIC24FJ256GA110 family devices, sorted by function, is shown in Table 1-4. Note that this table shows the pin location of individual peripheral features and not how they are multiplexed on the same pin. This information is provided in the pinout diagrams in the beginning of this data sheet. Multiplexed features are sorted by the priority given to a feature, with the highest priority peripheral being listed first. |
