3.21

Liquid crystal display controller (LCD)

The LCD drives up to 8 common terminals and 44 segment terminals to drive up to 320

pixels.

•

Internal step-up converter to guarantee functionality and contrast control irrespective of

VDD. This converter can be deactivated, in which case the VLCD pin is used to provide

the voltage to the LCD

•

Supports static, 1/2, 1/3, 1/4 and 1/8 duty

•

Supports static, 1/2, 1/3 and 1/4 bias

•

Phase inversion to reduce power consumption and EMI

•

Integrated voltage output buffers for higher LCD driving capability

•

Up to 8 pixels can be programmed to blink

•

Unneeded segments and common pins can be used as general I/O pins

•

LCD RAM can be updated at any time owing to a double-buffer

•

The LCD controller can operate in Stop mode

3.22

Random number generator (RNG)

All devices embed an RNG that delivers 32-bit random numbers generated by an integrated

analog circuit.

3.23

Advanced encryption standard hardware accelerator (AES)

The devices embed an AES hardware accelerator can be used to both encipher and

decipher data using AES algorithm.
