TZ1021MBG(O)

The TZ1021MBG is a product which belongs to the TZ1000 series, a family of processors for wearable devices. The TZ1021MBG incorporates a high performance 32-bit ARM® Cortex®-M4F RISC processor with 288 KB SRAM and 1 MB NOR flash memory, a high resolution 24-bit ?SADC, all in one package. The Cortex-M4F processor consists of a floating point processor unit, a memory protection unit, and a flexible interrupt controller. It supports many kinds of real time OS. The TZ1021MBG can select the most suitable power supply voltage and circuit to its operating frequency. Users can achieve the lowest power consumption in their applications to use the power saving mode.

The TZ1021MBG includes a low-power, large capacity 288 KB of SRAM, and a 1 MB NOR flash memory which is used to store program codes and data.

An AES engine and a random number generator are incorporated for a security function. The AES complies with FIPS (Federal Information Processing Standard) Publication 197, Advanced Encryption Standard. It can select a key length among 128 bits, 192 bits, and 256 bits, and executes the encryption and decryption without any processes of the processor.

The random number generator has passed the random number test of NIST SP800-22 (National Institute of Standards and Technology Special Publication 800-22), and it can be used for the bases of keys and others.

The 8 channel DMA controllers perform the data transfer between the SRAM and the peripheral such as the UART or between the SRAMs without any processes of the processor. The data transfer engine (SRAMC) in the SRAM controller enables the data transfer between the SRAMs without passing the data buses.

The TZ1021MBG also incorporates a 12-bit ADC and a 24-bit ?SADC. Without any special analog front-end devices, this 24-bit ?SADC allows the TZ1021MBG to be directly connected to a photo diode for pulse sensing, photoelectric sensors with small output voltage like for ECG measure applicati
