STC15W4K32S4-30I-LQFP44

The STC15W408AS-35I-TSSOP20 is an 8-bit microcontroller based on an enhanced 8051 CPU core, capable of operating at frequencies up to 30MHz. This device provides 32KB of Flash program memory and 26KB of EEPROM data memory, along with 42 I/O pins. It integrates a 10-bit Analog-to-Digital Converter (ADC) and supports a wide operating voltage range from 2.5V to 5.5V, with an operating temperature range of -40℃ to +85℃.

Key features include various reset functions such as Power-On Reset (POR), Watchdog Reset, and Software Reset, along with built-in general-purpose timers. The microcontroller is housed in a 44-lead LQFP package, suitable for surface mounting. Its design emphasizes high anti-interference and electrostatic discharge protection capabilities, making it suitable for robust applications.

This microcontroller is part of the STC15 series, known for its large capacity Flash program memory and SRAM data memory. It also integrates rich peripheral resources including multiple timers/counters, programmable clock output, high-precision internal IRC clock, comparator, enhanced PWM module, and various serial communication interfaces like UART, SPI, and I2C. The wide voltage working range and low-power modes, coupled with high anti-interference and strong electrostatic protection, enhance its reliability in demanding environments. Built-in In-System Programming (ISP) and In-Application Programming (IAP) functions simplify system development and firmware upgrades.
