200043EG

200043EG is a fictional microcontroller family used here as a neutral example of an embedded processing device. In this article it is presented as a hypothetical product of the company EG Components, designed to illustrate common features of mid-range 32-bit MCUs.

Technical overview: The core is a 32-bit ARM Cortex-M4 processor operating at up to 120 MHz. It includes 256 kilobytes of flash memory and 64 kilobytes of SRAM, with built-in boot ROM and security features for code protection.

Peripherals and interfaces: The device provides USB 2.0 full-speed, CAN, and multiple serial bridges (USART/UART, SPI, I2C), along with a 12-bit ADC array and several PWM timers. It supports real-time clock, watchdog, and hardware crypto accelerators for basic encryption tasks.

Power, packaging, and operating conditions: 200043EG is specified for 2.0 to 3.6V operation, with multiple power modes including a deep-sleep state. Typical configurations come in a 48-pin LQFP version, with a 64-pin variant available in some models.

Variants and software ecosystem: There are two marketed variants, 200043EG-A and 200043EG-B. The A model emphasizes economy with 256 KB flash and 64 KB RAM, while the B model adds 512 KB flash, 128 KB RAM, and an enhanced CAN interface. Development relies on EG Studio IDE, GCC-based toolchain, and SWD for debugging; libraries and middleware are provided for common protocols and sensor interfaces.
