EFM8BB21F16G-C-QFN20 Product Details

EFM8BB21F16G-C-QFN20 Overview


Packaged in a 20-UFQFN Exposed Pad format. A total of 16 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 Busy Bee 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 CIP-51 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 3V volts. The system has NO channels for DMA communication. There is 16kB memory size assigned to the part. At a frequency of 50MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 20 pins. There are 5 timers/counters in this device. It is equipped with a 8051 core architecture which is integrated into it.
