Recently, WAYON officially announced the launch of its new generation high-frequency 8051 core WY8S9003 series general-purpose microcontrollers. This MCU integrates dual operational amplifiers and comparators along with rich communication interfaces, making it highly suitable for BLDC motor control applications. It is also appropriate for wireless charging, BMS, security, consumer electronics, and other application fields.
The new WY8S9003 series uses the 8051 core as a high-speed data processing engine, with a wide operating voltage range of 2.2V~5.5V (at 25°C), meeting industrial grade requirements with an operating temperature of -40°C~105°C and high noise immunity. It supports 16KB Flash, 1KB XRAM, and a configurable LDROM boot area from 0~4KB. Its core processing speed can reach 48MHz, making it a high-frequency 8-bit general-purpose MCU.
The WY8S9003 series offers multiple packaging forms, including SSOP24, TSSOP20, QFN24, and QFN20, to flexibly meet the needs of various application scenarios.
