PIC24FV16KM204 FAMILY
1.1.4 EASY MIGRATION
The PIC24FV16KM204 family devices have two
variants. The KM20X variant provides the full feature set
of the device, while the KM10X offers a reduced periph-
eral set, allowing for the balance of features and cost
(refer to Table 1-1). Both variants allow for a smooth
migration path as applications grow and evolve.
The consistent pinout scheme used throughout the entire
family also helps in migrating to the next larger device.
This is true when moving between devices with the same
pin count, different die variants, or even moving from
20-pin or 28-pin devices to 44-pin/48-pin devices.
The PIC24F family is pin compatible with devices in the
dsPIC33 family, and shares some compatibility with the
pinout schema for PIC18 and dsPIC30. This extends
the ability of applications to grow from the relatively
simple to the powerful and complex, yet still selecting a
Microchip device.
1.2 Other Special Features
• Communications: The PIC24FV16KM204 family
incorporates a range of serial communication
peripherals to handle a range of application
requirements. There is an MSSP module which
implements both SPI and I²C™ protocols, and
supports both Master and Slave modes of
operation for each. Devices also include one of
two UARTs with built-in IrDA^® encoders/decoders.
• Analog Features: Select members of the
PIC24FV16KM204 family include two 8-bit
Digital-to-Analog Converters which offer support
in Idle mode, and left and right-justified input data,
as well as up to two operational amplifiers with
selectable power and speed modes.
• Real-Time Clock/Calendar (RTCC): This module
implements a full-featured clock and calendar with
alarm functions in hardware, freeing up timer
resources and program memory space for use of
the core application.
• 12-Bit A/D Converter: This module incorporates
programmable acquisition time, allowing for a
channel to be selected and a conversion to be
initiated without waiting for a sampling period and
faster sampling speed. The 16-deep result buffer
can be used either in Sleep, to reduce power, or in
Active mode to improve throughput.
• Charge Time Measurement Unit (CTMU) Interface:
The PIC24FV16KM204 family includes the new
CTMU interface module, which can be used for
capacitive touch sensing, proximity sensing, and
also for precision time measurement and pulse
generation. The CTMU can also be connected to
the operational amplifiers to provide active guard-
ing, which provides increased robustness in the
presence of noise in capacitive touch applications.
1.3 Details on Individual Family
Members
Devices in the PIC24FV16KM204 family are available
in 20-pin, 28-pin, 44-pin and 48-pin packages. The
general block diagram for all devices is shown in
Figure 1-1.
Members of the PIC24FV16KM204 family are available
as both standard and high-voltage devices. High-voltage
devices, designated with an “FV” in the part number
(such as PIC24FV16KM204), accommodate an operat-
ing VDD range of 2.0V to 5.5V and have an on-board
voltage regulator that powers the core. Peripherals
operate at VDD.
Standard devices, designated by “F” (such as
PIC24F16KM204), function over a lower VDD range of
1.8V to 3.6V. These parts do not have an internal regu-
lator, and both the core and peripherals operate directly
from VDD.
The PIC24FV16KM204 family may be thought of as
two different device groups, both offering slightly differ-
ent sets of features. These differ from each other in
multiple ways:
• The size of the Flash program memory
• The number of external analog channels available
• The number of Digital-to-Analog Converters
• The number of operational amplifiers
• The number of analog comparators
• The presence of a Real-Time Clock and Calendar
(RTCC)
• The number and type of CCP modules (i.e.,
MCCP vs. SCCP)
• The number of serial communication modules
(both MSSPs and UARTs)
• The number of Configurable Logic
Cell (CLC) modules.
The general differences between the different
sub-families are shown in Table 1-1 and Table 1-2.
A list of the pin features available on the
PIC24FV16KM204 family devices, sorted by function,
is provided in Table 1-5.
