The Charge Time Measurement Unit (CTMU) is a
flexible analog module that provides accurate differen-
tial time measurement between pulse sources, as well
as asynchronous pulse generation. By working with
other on-chip analog modules, the CTMU can precisely
measure time, capacitance and relative changes in
capacitance or generate output pulses with a specific
time delay. The CTMU is ideal for interfacing with
capacitive-based sensors.
The module includes these key features:
• Up to 11 channels available for capacitive or time
• Low-cost temperature measurement using on-chip
• On-chip precision current source
• Four-edge input trigger sources
• Polarity control for each edge source

• Control of edge sequence
• Control of response to edges
• Time measurement resolution of 1 nanosecond
• High-precision time measurement
• Time delay of external or internal signal
• Accurate current source suitable for capacitive
The CTMU works in conjunction with the A/D Converter
to provide up to 11 channels for time or charge
measurement, depending on the specific device and
the number of A/D channels available. When config-
ured for time delay, the CTMU is connected to one of
the analog comparators. The level-sensitive input edge
sources can be selected from four sources: two
external inputs or the ECCP1/CCP2 Special Event
Triggers.
The CTMU special event can trigger the Analog-to-Digital
Converter module.
