2.28
Cryptographic co-processor (C3)
Main features:
●
Supported cryptographic algorithms:
–
Advanced encryption standard (AES) cipher in ECB, CBC, CTR modes
–
Data encryption standard (DES) cipher in ECB and CBC modes.
–
SHA-1, HMAC-SHA-1, MD5, HMAC-MD5 digests.
●
Instruction driven DMA based programmable engine.
●
AHB master port for data access from/to system memory.
●
AHB slave port for co-processor register accesses and initial engine-setup
●
The co-processor is fully autonomous (DMA input reading, cryptographic operation
execution, DMA output writing) after being set up by the host processor
●
The co-processor executes programs written by the host in memory, it can execute an
unlimited list of programs.
●
The co-processor supports hardware chaining of cryptographic blocks for optimized
execution of data-flow requiring multiple algorithms processing over the same set of
data (for example encryption + hashing on the fly)
2.29
8-channel ADC
Main features:
●
Successive approximation conversion method
●
10-bit resolution @1 Msps
●
Hardware supporting up to 13.5 bits resolution at 8 ksps by oversampling and
accumulation
●
Eight analog input (AIN) channels, ranging from 0 to 2.5 V
●
INL ± 1 LSB, DNL ± 1 LSB
●
Programmable conversion speed, (min. conversion time is 1 s)
●
Programmable average results from 1 (no averaging) up to 128
●
Programmable auto scan for all the eight channels.
●
Normal or enhanced mode;
–
In normal mode the conversion start upon CPU request
–
In enhanced mode the ADC converts continuously the selected channels inserting
a selectable amount of time between two conversions.
2.30
1-bit DAC
The one-bit DAC is a second-order noise shaper based on the TDM hardware. The action
memory determines whether a new sample needs to be sent to the DAC during the next
byte. Samples are read from the buffer memory.
