PIC16LF777-I/PT

Microcontrollers Overview

The PIC16LF777-I/PT is an 8-bit CMOS microcontroller from the PIC16(L)F7x7 family, manufactured by Microchip Technology. It features a 44-pin TQFP package and utilizes Flash memory technology for program storage. The device operates with a DC to 20 MHz oscillator/clock input and supports a wide operating voltage range of 2V to 5.5V. Key specifications include 14KB of Flash program memory, 368 bytes of SRAM, and 256 bytes of EEPROM. It provides 35 general-purpose I/O pins, a 10-bit 14-channel ADC, two comparators, and standard communication interfaces including USART, SPI, and I2C.

Microcontrollers Feature Summary

• Supports low-voltage operation down to 2V, enabling compatibility with battery-powered systems.
• Includes programmable watchdog timer, oscillator start-up timer, and power-up reset for system reliability.
• Features in-circuit serial programming (ICSP) via two pins for efficient development and debugging.
• Integrates multiple peripheral modules such as timers, capture/compare/PWM units, and analog-to-digital conversion.

Microcontrollers Applications

• Industrial control systems requiring robust 8-bit processing
• Automotive electronic applications within specified temperature ranges
• Consumer electronics utilizing low-voltage power sources
• Embedded sensor interfaces with analog signal conditioning

Microcontrollers Procurement Notes

Verify the specific suffix 'I/PT' to confirm industrial temperature range (-40°C to +85°C) and TQFP-44 packaging. Ensure the part number matches the exact datasheet revision for accurate electrical characteristics. Confirm RoHS compliance status if required for your manufacturing process. Cross-reference the manufacturer's official documentation to validate pinout assignments and memory maps before integration.

Microcontrollers Selection Notes

Select this component when a balance of moderate Flash capacity and extensive analog peripherals is required in a 44-pin form factor. It is suitable for designs needing multiple ADC channels and communication interfaces without the complexity of higher-pin-count devices. Consider the 2V minimum voltage requirement for low-power applications compared to standard 5V-only variants.

Microcontrollers Part Context

This microcontroller belongs to the PIC16(L)F7x7 family, which offers enhanced peripheral sets compared to earlier PIC16 series devices. The family is designed for cost-sensitive applications requiring reliable performance in harsh environments. The 'LF' designation indicates low-voltage operation, while 'I' denotes the industrial temperature grade, distinguishing it from commercial or automotive-specific variants.

Microcontrollers Replacement Considerations

Direct replacements within the same family include PIC16F777-I/PT for standard voltage applications. For pin-compatible upgrades with increased memory, consider the PIC16F887-I/PT, though verification of software compatibility and peripheral mapping is essential due to architectural differences between the 7x7 and 887 series.
