The AT89C2051-24SU is an 8-bit CMOS microcontroller based on the 8051 architecture, manufactured by Microchip Technology. It integrates 2KB of reprogrammable Flash memory with endurance of 10,000 write/erase cycles, 128 bytes of internal RAM, and 15 programmable I/O lines. The device operates at a maximum clock frequency of 24 MHz with a supply voltage range of 2.7V to 6V (full static operation down to 0 Hz).
Key peripherals include two 16-bit timer/counters, a full-duplex UART serial port, an on-chip analog comparator, and direct LED drive outputs. The microcontroller supports six interrupt sources with two priority levels and offers low-power Idle and Power-down modes. The internal oscillator eliminates the need for external clock components.
The AT89C2051-24SU is housed in a 20-lead SOIC package (0.295" width, 7.50mm pitch) with surface mount mounting. The operating temperature range is -40°C to +85°C, making it suitable for industrial environments. This device is compatible with the standard MCS-51 instruction set and provides a flexible, cost-effective solution for embedded control applications.
The DB records a supply voltage of 4V-6V, while the datasheet specifies an operating range of 2.7V to 6V. For 24MHz operation, a minimum supply of 4V is recommended.
It comes in a 20-SOIC (0.295", 7.50mm Width) surface mount package.
The operating temperature range is -40°C to +85°C.
It is marked as RoHS3 compliant and REACH unaffected, but compliance has not been verified with certificates.
It has 2KB (2K x 8) of Flash memory with 10,000 write/erase cycles endurance.
It has 15 programmable I/O lines.
Two 16-bit timer/counters, a full-duplex UART serial port, an on-chip analog comparator, direct LED drive outputs, and six interrupt sources.
