TWR-K21D50M Tower Module User’s Manual
Three FlexTimers with a total of 12 channels
Hardware dead-time insertion and quadrature decoding for motor
control
Carrier modulator timer for infrared waveform generation in remote
control applications
Four-channel 32-bit periodic interrupt timer provides time base for
RTOS task scheduler, or trigger source for ADC conversion and
programmable delay block
Full-Speed USB Device/Host/On-The-Go with device charge detect
capability
Optimized charging current/time for portable USB devices, enabling
longer battery life
USB low-voltage regulator that supplies up to 120 mA off chip at 3.3
volts to power external components from 5-volt input
Four UARTs:
One Inter-IC Sound (I
Two DSPI modules and two I
Hardware encryption co-processor for secure data transfer and storage.
Faster-than-software implementations with minimal CPU loading.
Supports a wide variety of algorithms - DES, 3DES, AES, MD5, SHA-1,
SHA-256
System security and tamper detection with secure real-time clock (RTC)
and independent battery supply. Secure key storage with
internal/external tamper detection for unsecured flash, temperature,
clock, and supply voltage variations and physical attack detection
Memory protection unit provides memory protection for all masters on
the crossbar switch, increasing software reliability
Cyclic redundancy check (CRC) engine validates memory contents and
communication data, increasing system reliability
Independently-clocked COP guards against clock skew or code runaway
for fail-safe applications such as the IEC 60730 safety standard for
household appliances
External watchdog monitor drives output pin to safe state for external
components in the event that a watchdog timeout occurs
Included in Freescale’s product longevity program, with assured supply
for a minimum of 10 years after launch
o one UART that supports RS232 with flow control, RS485,
o three UARTs that support RS232 with flow control and RS485
