PIC16LF877-04/PQ

Microcontrollers Overview

The PIC16LF877-04/PQ is an 8-bit microcontroller from the PIC16 family, manufactured by Microchip Technology. It features a PIC core architecture with 14 kB of Flash program memory and 368 bytes of data RAM. The device operates at a maximum clock frequency of 4 MHz and includes 256 bytes of EEPROM for data storage. It provides 33 general-purpose I/O lines and integrates an 8-channel, 10-bit Analog-to-Digital Converter (ADC). Key communication interfaces include MSSP (supporting SPI and I2C) and USART. The unit is housed in a 44-pin MQFP package and supports a supply voltage range of 4.0 V to 5.5 V.

Microcontrollers Feature Summary

• Sensor interface circuits utilizing analog input channels
• Communication gateway nodes using serial protocols
• Battery-powered embedded devices due to low-voltage operation

Microcontrollers Procurement Notes

Verify the specific suffix '04' indicates the 4 MHz speed grade and 'PQ' denotes the MQFP-44 package type. Confirm RoHS compliance status through official Microchip documentation or authorized distributor datasheets. Ensure the operating temperature range meets application requirements, as commercial grade variants typically span 0°C to +70°C. Cross-reference the manufacturer part number directly with the component marking to avoid counterfeit risks.

Microcontrollers Selection Notes

Select this component when a low-power 8-bit MCU with integrated analog capabilities is required. The 4 MHz limit suits applications not demanding high-speed processing. Compare against the PIC16F877 series if higher clock speeds up to 20 MHz are necessary, noting that the LF variant offers extended voltage ranges and lower power consumption. Verify package availability, as MQFP-44 may have different lead times compared to standard DIP packages.

Microcontrollers Part Context

This device belongs to the PIC16(L)F87x family of 8-bit CMOS Flash microcontrollers. It shares architectural similarities with other members like the PIC16F877A but differs in speed grades and package options. The LF designation signifies Low Power functionality, optimized for battery-operated applications within the standard PIC16 instruction set environment.

Microcontrollers Replacement Considerations

Direct substitutes include the PIC16LF877-04/IQ for industrial temperature range in the same package. For higher performance, the PIC16F877A-I/ML offers 20 MHz operation in a QCC44 package, though pin compatibility must be verified. Check for updated revisions such as the PIC16LF877A series which may offer enhanced features while maintaining functional equivalence.
