C8051F991-GM Product Details

C8051F991-GM Overview


There is a 20-UFQFN Exposed Pad package available. The board has 16 I/Os. Using the Mounting Type Surface Mount, the MCU is mounted on PCB. A 8-Bit core is used in order to power the IC chip. The type of memory it uses for its program is FLASH. -40°C~85°C TA is the temperature range at which this Microcontroller operates. C8051F9xx-series components are electrical components. In the case of this Microcontroller, the memory size of the program is 8KB 8K x 8. Powered by a CIP-51 8051 Core processor. Microcontroller's a MICROCONTROLLER uPs/uCs/Peripheral IC. IC Chip terminations are 20. As a result, this Microcontroller comes with a 8-bit size. Input voltage for the chip is 2.4V volts. A total of NO DMA channels are available. This IC part has a memory size of 8kB. There are a number of alternatives to the base part number C8051F99 that you can find. Performing well when operated at frequency 25MHz can be achieved. Using YES PWM channels, the device works. On the chip, there are 20 pins that can be accessed. It comes with 4 timers/counters that can be set up. The pins counted are 20. The CPU is based on 8051 cores.
