MC9S08RE8FGE

The MC9S08RE8FGE is a microcontroller from the S08 family from NXP Semiconductors (formerly Freescale). It is designed for extreme low-power, embedded applications in which extremely low current draw is necessary. The MC9S08RE8FGE is a single-core 16-bit processor with a 25 MHz clock frequency and 128 KB Flash memory. Its most notable features are its low current draw, low cost, and minimal size (the die area is only 3.00 x 3.00 mm).

The MC9S08RE8FGE is used in a wide range of applications, including automotive, industrial controls, consumer electronics, medical, and interactive gaming. Typical applications for the MC9S08RE8FGE include motor control, power management, and safety systems.

The MC9S08RE8FGE has several key features that enable it to provide exceptional low-power performance. Its low-voltage range allows the power supply to be down to as low as 1.8V. This helps reduce the active-mode current draw down to as little as 0.5 μA. It also includes a deep sleep mode, allowing the current draw to drop further down to approximately 25 nA. Additionally, the MC9S08RE8FGE includes an ultra-low-power wakeup pin input, allowing an external device to wake the processor up.

The MC9S08RE8FGE has several peripherals that allow it to be used in different applications. It includes UART, SPI, I2C, and I/O interfaces for connecting to external devices. It also includes several timers/counters, PWM, and analog comparators for controlling different devices.

The MC9S08RE8FGE runs an 8-bit execution system that is compatible with traditional 8051 architectures. The processor has an 8-bit data bus, 16-bit program counters and index registers, and 24-bit address space. The microcontroller also has several 16-bit and 32-bit peripheral registers.

The MC9S08RE8FGE has several on-chip debug features, including a breakpoint register, Watchdog timers, On-chip Serial Wire Debug (SWD) and non-invasive BDM (NBDM) support. Additionally, it includes a Flash, RAM, and Registers Manager to aid in the development and debugging of programs.

The MC9S08RE8FGE is a versatile microcontroller that is well-suited for a wide range of embedded applications. Its low-power capabilities, small package size, and integrated debug features make it an attractive choice for many applications. Its 8-bit architecture is also compatible with existing 8051 applications, allowing for compatibility and easy migration from one platform to another.
