for both program memory and data EEPROM are
rated to last for many thousands of erase/write
cycles – up to 100,000 for program memory and
1,000,000 for EEPROM. Data retention without
refresh is conservatively estimated to be greater
than 100 years.
to their own program memory spaces under inter-
nal software control. By using a bootloader routine
located in the protected Boot Block at the top of
program memory, it becomes possible to create
an application that can update itself in the field.
this module provides 1, 2 or 4 modulated outputs
for controlling half-bridge and full-bridge drivers.
Other features include auto-shutdown on Fault
detection and auto-restart to reactivate outputs
once the condition has cleared.
module is capable of standard RS-232 operation
using the internal oscillator block, removing the
need for an external crystal (and its
accompanying power requirement) in applications
that talk to the outside world. This module also
includes Auto-Baud Detect and LIN capability.
Other Special Features
Preliminary
• High-Speed 10-Bit A/D Converter: This module
• Motion Feedback Module (MFM): This module
• Extended Watchdog Timer (WDT): This
incorporates programmable acquisition time,
allowing for a channel to be selected and a
conversion to be initiated without waiting for a
sampling period and thus, reducing code
overhead.
features a Quadrature Encoder Interface (QEI)
and an Input Capture (IC) module. The QEI
accepts two phase inputs (QEA, QEB) and one
index input (INDX) from an incremental encoder.
The QEI supports high and low precision position
tracking, direction status and change of direction
interrupt and velocity measurement. The input
capture features 3 channels of independent input
capture with Timer5 as the time base, a Special
Event Trigger to other modules and an adjustable
noise filter on each IC input.
enhanced version incorporates a 16-bit prescaler,
allowing a time-out range from 4 ms to over
2 minutes, that is stable across operating voltage
and temperature.
