Microchip PIC16C73B-04I/SO: An 8-Bit CMOS Microcontroller with Integrated EEPROM
The Microchip PIC16C73B-04I/SO represents a pivotal component in the landscape of embedded control, combining a robust 8-bit architecture with the invaluable addition of on-chip EEPROM data memory. This microcontroller is engineered for applications demanding reliable performance, low power consumption, and non-volatile data storage capabilities.
Housed in a compact 28-pin SOIC (Small Outline Integrated Circuit) package, the ‘-04I’ suffix denotes its capability to operate at industrial temperature ranges (-40°C to +85°C) with a clock frequency of up to 4 MHz. At its core lies a high-performance RISC CPU, featuring a reduced instruction set that enables most commands to execute in a single clock cycle. This design ensures high computational efficiency, achieving up to 1 MIPS per MHz and allowing for deterministic response in time-critical applications.
A defining feature of this microcontroller is its integrated Electrically Erasable Programmable Read-Only Memory (EEPROM). This memory block is separate from the main program memory and can be written to and read from during normal operation. This capability is crucial for storing critical calibration data, user settings, or system parameters that must be retained even after a power cycle, eliminating the need for an external serial EEPROM chip and thus reducing system cost and complexity.
The peripheral set of the PIC16C73B is comprehensive. It includes three versatile timers/counters, including one with a pre-scaler. For analog interfacing, it is equipped with a 5-channel 8-bit analog-to-digital converter (ADC), enabling direct sensor data acquisition. Communication is facilitated through both a Universal Synchronous Asynchronous Receiver Transmitter (USART) for serial communication (RS-232, RS-485) and an Inter-Integrated Circuit (I²C) bus for communicating with other peripherals. Furthermore, it incorporates a Capture/Compare/PWM (CCP) module, offering precision control for tasks like driving motors or regulating power.
Built using CMOS technology, the device is renowned for its low power consumption, making it an excellent choice for battery-powered or energy-sensitive devices. Its operating voltage range is wide, typically from 3.0V to 5.5V. The microcontroller also supports multiple power-saving modes, including SLEEP, to further minimize power draw when idle.
In summary, the PIC16C73B-04I/SO is a versatile and powerful solution for a vast array of embedded designs, from industrial automation and sensor nodes to consumer electronics and automotive systems.
