The C8051F124R is an embedded integrated device used in a wide variety of automation, monitoring, and control applications. The C8051F124R is a member of the Silicon Laboratories C8051F12x family of 8-bit mixed-signal microcontrollers. The device is designed with a mixed-signal core optimized for high performance, ultra-low power consumption, and extremely low-power standby modes.The C8051F124R features a 16KB of on-chip ROM, an 8KB of on-chip Flash ROM, an 8KB of RAM, and a full range of on-chip peripherals, including Universal Synchronous/Asynchronous Receiver Transmitter (USART), Inter-Integrated Circuit (I2C), and Serial Peripheral Interface (SPI) for communication with external devices as well as a high precision Analog-to-Digital Converter (ADC) for reading analog signals. The on-chip peripherals are designed for low power consumption, high accuracy and fast response time. Moreover, the device also features a wide array of on-chip debug and test functions, enabling comprehensive system diagnosis and debugging prior to the production stage.

The C8051F124R incorporates a 16-bit single-cycle 8031 core derived from the popular 8051 core architecture. It is optimized specifically for lower-power operation while still providing high-performance and fast response times. The 8051 core executes instructions in a single cycle, and features an enhanced interrupt controller as well as hardware multiply and divide instructions. The C8051F124R includes several advanced features to support real-time applications, including a unique low-power mode, a three-stage programmable watchdog timer and two sleep modes.

In terms of clock system, the 12-pin C8051F124R features an integrated oscillator for stable operation without external components; also an auxiliary crystal oscillator is available for more accurate clock sources. The Clock Generation Unit (CGU) of the device provides an optimal clock frequency selection from multiple clock sources, it also allows the system clock to be clocked from an external clock source.

The C8051F124R is available in a 16-pin surface-mount package, making it suitable for small form factor embedded applications. The device can operate on a single 3V supply, with a 20mA current rating for 3.3V supply voltage. Additionally, the device features two low power saving modes, including a Sleep Mode and Power Down Mode. The Sleep Mode reduces the current down to 100μA, while the Power Down Mode reduces the current down to 1μA.

Overall, The C8051F124R is an ideal solution for a range of low-power, cost-effective and highly integrated embedded applications. It offers an 8-bit core, low power modes, multiple I/O interface options and integrated peripherals, all in a small form factor at an attractive price point. Furthermore, its extensive on-chip debug and test capabilities make the C8051F124R a reliable, flexible, and powerful embedded controller that can simplify design and reduce development time.
