The Holychip HC18P133L-SSOP24-T is a Other Processors and Microcontrollers (MCUs) SSOP-24 RoHS component. It is a low-power 8-bit microcontroller that is based on an 80C51 instruction-set compatible core and has been optimized for extended code and data memory applications. This from Holychip allows flexibility to users in creating microcontroller solutions for their specific applications with features such as clock outputs, watchdog timer, sleep mode and up to 8 external interrupts. It includes 4K bytes ROM, 8K bytes internal RAM, 1Kbytes EEPROM, 8 I/O, 2 x 16bit Timer/Counter, SPI, UART, LCM and 1A/D. In addition to the integrated peripherals, users can take advantage of the onboard SPI, UART and CAN2.0 bus-interface for communication with external components. This MCU supports up to 36MHz core clock speed, and is designed for low-power, low-cost applications.
