Working Principle

The C8051F997-C-GMR device consists of a die containing an 8-bit, pipelined, single-cycle CPU, 1-KByte Flash memory, 74-KByte RAM, and a peripheral suite.The processor core includes a program counter, an instruction register, an arithmetic logic unit (ALU), a register file, a status register, and a data bus interface. The ALU performs 8-bit arithmetic operations such as addition, subtraction, multiplication, and division. The instruction set includes instructions for basic operations, jump, call and return instructions, logical operations, bit manipulation, value comparison, and shift operations. The device also incorporates hardware characteristics such as low-power operation, hardware support for interrupts and serial communication, and system-level design features such as built-in watchdogs and clock sources.The C8051F997-C-GMR also features peripheral and system features such as a 12-bit ADC, a 6-channel DMA, a 32-KByte memory, a built-in real-time clock, and an 8-bit pulse width modulator (PWM). The ADC is capable of converting single-ended, differential, or pseudodifferential signals and supports a variety of sample rates. The DMA controller supports up to six channels for transfer requests and provides support for USB, I2C, SPI, and UART transfers.The on-chip 32K-Byte memory provides user-programmable code or data storage available for shared code and data with the host processor. The 8-bit PWM generator can generate waveforms up to 10MHz with adjustable duty cycles. The real-time clock (RTC) can be used to implement periodic tasks, such as periodic data sampling, while the device is in low-power modes.
