EFM8BB21F16I-C-QSOP24R Product Details

EFM8BB21F16I-C-QSOP24R Overview


Packaged in a 24-SSOP (0.154, 3.90mm Width) format. A total of 21 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~125°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 24 terminations on the IC chip, which means there are 24 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. This MCU Chip uses YES PWM channels to operate. It runs on a 50MHz clock.
