HR6P91

Features

• The HR6P series 8-bit microcontroller uses a reduced instruction set computing (RISC) Harvard (HARVARD) architecture, has an embedded hardware multiplier, and is designed with special user code encryption, so the instructions have high confidentiality and high execution efficiency.

In the product line, program memory includes OTP, FLASH and other types. The chip integrates a rich set of peripherals, including timer, PWM, ADC, analog comparator, LCD DRIVER, embedded EEPROM, communication module, etc. The chip is manufactured using deep pressure micron static CMOS process, with a wide operating temperature and voltage range that meets industrial standards; in addition, the industry-leading high reliability and high anti-interference performance are the outstanding features of Haier microcontroller products.

• Haier's microcontroller products have been widely used in various application fields such as home appliances, security, multimedia, industrial control, smart grid and automotive electronics.
