Robot UI core function
Mar 17, 2018

The system architecture of the robot UI core is mainly: 32-bit RISC processor; the highest frequency can reach 24MHz; the system supports low-power sleep mode; supports serial debugging (SWD) interface; 8-way PDMA supports fast data transmission.


On the power management content of the robot UI core: usually its wide voltage operating range is 2.7 to 5.5 volts.

The internal 1.8 V LDO is used to power the internal logic; the coin cell battery supply pin is used to power the RTC, and the input range is 2.0 to 3.6V. At the same time, the system includes four low-power modes: sleep mode, deep sleep mode 1, deep sleep mode 2, and power-down mode. Generally, in power-down mode, the power consumption is less than 100uA, and the operating power consumption is typically 5 to 10mA.


In terms of storage, usually the UI chip 64 KB on-chip Flash is used to store user programs; 4 KB SRAM is used as internal cache memory.


From the perspective of security, the UI sheet Flash partition read protection configuration; JTAG interface can be permanently shielded, the chip does not exist other debugging methods can operate on the flash; support true random number for encryption; support CRC verification; 32 bits ID, each chip has a unique ID number for code protection.


Typical applications on the UI core are: The product can be used in household cleaning robots and other products, but also includes WIFI functions, wireless remote control functions, UI with a display screen. In addition, UI chips can also be used for car CDs.
