AT89C4051-24SJ Product Details

AT89C4051-24SJ Overview


Packaged in a 20-SOIC (0.295, 7.50mm Width) format. A total of 15 I/Os are on the Microcontroller. Surface Mount is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 8-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A 89C series electrical component is used in this application. This program has a program memory of 4KB 4K x 8 bytes, which is the size of the program. With a 8051 Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER uPs/uCs/peripheral parts. There are 20 terminations on the IC chip, which means there are 20 terminations on the integrated circuit chip. In addition, MCU chip comes with a 8-bit size. Microcontroller chip has outputs of 5V volts. The system has NO channels for DMA communication. Alternatives can be found by searching through the base part number AT89C4051 to find them. This MCU Chip uses NO PWM channels to operate. It runs on a 24MHz clock.
