U264C

U264C is a designation used in multiple, unrelated fields to label distinct items that share the same alphanumeric code. Because it is not unique to a single product or concept, the meaning of U264C must be inferred from its domain and context.

In genetics, U264C denotes a point mutation in an RNA or coding sequence, indicating that at position 264, a uracil (U) is replaced by cytosine (C). This type of notation is common in sequence alignment and mutation reports. The biological effect of the substitution depends on the gene, the region within the transcript, and the functional role of the altered nucleotide. In some contexts, such a change could affect RNA structure, protein coding, or regulatory elements.

In electronics and embedded systems, U264C is used as a part number for a hypothetical family of microcontrollers designed for low-power applications. The U264C line is described as a 32-bit MCU with a compact feature set suitable for IoT devices and small appliances. Typical specifications might include a 32-bit CPU core, up to 128 KB of flash memory, 8–32 KB of RAM, and peripherals such as UART, SPI, I2C, ADCs, and timers. The series emphasizes energy efficiency and simple integration, with standard development tools and low-power sleep modes.
