The AT89C4051-24SU is an 8-bit microcontroller based on the industry-standard 8051 core, manufactured by Atmel. It features 4KB of reprogrammable Flash memory with 10,000 write/erase cycles and 128 bytes of internal RAM. The device operates at speeds up to 24 MHz and supports a supply voltage range of 2.7V to 6V. Peripheral features include 15 programmable I/O lines, a full-duplex UART serial port, two 16-bit timer/counters, six interrupt sources, and an on-chip precision analog comparator. Additional integrated functions include brown-out detection, power-on reset (POR), and direct LED drive outputs.
The microcontroller offers two software-selectable power-saving modes: Idle mode (which stops the CPU while allowing RAM, timers, serial port, and interrupt system to continue) and Power-down mode (which freezes the oscillator and disables all chip functions except RAM retention). The AT89C4051-24SU is designed for low-voltage, high-performance embedded applications.
The device is housed in a 20-pin SOIC (0.295-inch, 7.50mm width) surface-mount package, with a supplier device package of 20-SOIC. It operates over a temperature range of -40°C to 85°C and uses an internal oscillator. The package is RoHS3 compliant and has a moisture sensitivity level of 1 (unlimited).
The operating voltage range is 2.7V to 6V according to the datasheet.
