DS89C420-QCL Product Details

DS89C420-QCL Overview


Packaged in a 44-LCC (J-Lead) format. A total of 32 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 0°C~70°C TA. A 89C series electrical component is used in this application. This program has a program memory of 16KB 16K 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 44 terminations on the IC chip, which means there are 44 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. There is 16kB memory size assigned to the part. Alternatives can be found by searching through the base part number DS89C420 to find them. At a frequency of 33MHz, Microcontroller can operate efficiently. This MCU Chip uses NO PWM channels to operate. In total, it has 44 pins.
