The Microchip PIC16C716-04I/P: A Robust 8-Bit Microcontroller with Integrated EEPROM

In the realm of embedded control, the choice of microcontroller is pivotal, balancing processing capability, peripheral integration, and data retention features. The Microchip PIC16C716-04I/P stands out as a dedicated solution designed for applications requiring non-volatile data storage alongside reliable 8-bit computational performance. This member of the venerable PIC® mid-range family combines core processing strengths with the critical advantage of on-chip EEPROM data memory, making it a compelling choice for a wide array of industrial, automotive, and consumer applications.

Housed in a plastic DIP (PDIP) package, the PIC16C716-04I/P is built upon a high-performance RISC architecture. Its core operates at a clock speed of 4 MHz, indicated by the "-04" speed grade, and is capable of executing most instructions in a single cycle, achieving a throughput of up to 1 MIPS. This efficiency ensures responsive control for real-time tasks. The device features 2K x 14 words of Flash program memory and 128 x 8 bytes of RAM for data handling. However, its most significant attribute is the integrated 128 x 8 bytes of EEPROM data memory. This memory space can be electrically erased and rewritten, allowing system parameters, calibration data, or user settings to be stored directly on the microcontroller without requiring an external serial EEPROM chip, thereby reducing component count, board space, and system cost.

The peripheral set of the PIC16C716 is tailored for control-oriented tasks. It includes a 13-bit counter with a prescaler, a real-time clock counter (RTCC), and a watchdog timer (WDT) with its own on-chip RC oscillator for reliable operation. For analog interfacing, it is equipped with a 5-channel analog-to-digital converter (ADC) with 8-bit resolution, enabling direct connection to sensors monitoring voltage, temperature, or other environmental factors. With 22 I/O pins, it offers sufficient digital connectivity for switches, LEDs, and other digital peripherals.

The operational voltage range of 2.5V to 6.0V makes it suitable for both battery-powered and mains-derived applications. Its extended industrial temperature range (-40°C to +85°C) ensures stable and dependable performance in environmentally challenging conditions.

ICGOODFIND: The Microchip PIC16C716-04I/P is a highly integrated and robust controller that excels in systems where persistent data storage is paramount. Its combination of core processing power, essential analog and digital peripherals, and the invaluable embedded EEPROM makes it an efficient and cost-effective single-chip solution for enduring and reliable embedded designs.
