20067EC

20067EC is a fictional catalog number used to describe a family of compact microcontrollers in this article. It serves as a case study to illustrate typical features, naming conventions, and documentation practices used in embedded systems design. No real-world product with this exact designation is manufactured.

Overview and features: The imagined 20067EC is a 32-bit MCU built around a low-power, general-purpose core compatible with common ARM Cortex-M instruction sets. It is described as operating up to 48 MHz, with on-chip flash memory of 128 kilobytes and SRAM of 16 kilobytes. The device includes a range of peripherals such as UART, SPI, I2C, a 10-bit ADC, PWM channels, and a real-time clock.

Power, packages, and interfaces: The fictional device targets 1.8 to 3.3-volt systems and supports multiple sleep modes for low-power operation. It is depicted in 28-pin and 48-pin packages, with a variety of pinouts to accommodate simple sensors and compact control tasks.

Development and usage: In the article’s context, 20067EC is used in teaching materials and demonstration bill of materials to illustrate common design decisions and documentation practices. It is not linked to any current production line or supplier.

Variants and name conventions: The entry mentions 20067EC-A, 20067EC-B, and 20067EC-C as hypothetical revisions that may differ in memory size, peripheral set, or voltage range.
