The AT89S4051-24SU is a low-voltage, high-performance 8-bit microcontroller based on the industry-standard 8051 architecture. It integrates 4KB of In-System Programmable (ISP) Flash memory and 256 bytes of internal RAM, enabling flexible embedded control applications. The device operates at a maximum frequency of 24 MHz and supports a wide supply voltage range of 2.7V to 5.5V, making it suitable for battery-powered and industrial designs.
Key peripherals include 15 programmable I/O lines, a full-duplex enhanced UART serial port, two 16-bit timer/counters, an on-chip analog comparator, and an 8-bit PWM output. The microcontroller also features a brown-out detect/reset, power-on reset, and internal oscillator, reducing external component count. With six interrupt sources and a four-level interrupt controller, it provides responsive real-time control.
The AT89S4051-24SU is packaged in a 20-pin SOIC surface mount package (7.5 mm width, 13 mm length, 2.35 mm height) and is supplied in rail/tube. It is designed for operating temperatures from -40°C to +85°C, making it reliable in harsh environments. The ISP Flash memory allows for easy firmware updates via a serial interface, supporting byte and page programming modes.
The operating voltage range is 2.7V to 5.5V.
