- Peripheral Pin Select (PPS) allows flexible remapping of digital peripherals including EUSART, SPI, and I2C to any I/O pin, simplifying PCB routing
- Integrated 10-bit ADC with computation (ADC2) and on-chip DAC support analog signal acquisition and generation without external converter ICs
Applications
The PIC16LF18877-I/PT is well-suited for low-power embedded control applications in consumer appliances, HVAC controllers, and industrial sensor nodes where its 1.8V minimum supply and 32 MHz PIC16 core balance performance with battery longevity. The Peripheral Pin Select flexibility simplifies PCB layout in space-constrained designs such as wearable devices and smart home modules that require multiple serial communication interfaces. Its on-chip EEPROM, DAC, and 10-bit ADC also make it a cost-effective single-chip solution for data logging, analog control loops, and field-configurable sensor interfaces.

Frequently Asked Questions
At what minimum supply voltage can the PIC16LF18877-I/PT run and at what clock speed?
The PIC16LF18877-I/PT operates from a minimum supply of 1.8V at up to 16 MHz, making it suitable for single-cell lithium-ion battery designs. At higher supply voltages up to 3.6V, the full 32 MHz clock speed is available for more demanding processing tasks.
How does the Peripheral Pin Select (PPS) feature benefit a multi-interface PCB layout with PIC16LF18877-I/PT?
The PIC16LF18877-I/PT Peripheral Pin Select allows digital peripherals such as EUSART, SPI, and I2C to be freely assigned to most I/O pins, eliminating fixed-pin constraints. This flexibility can reduce PCB trace crossing and via count in multi-layer designs, particularly beneficial in 44-pin TQFP layouts with limited routing channels.
Does the PIC16LF18877-I/PT include non-volatile data storage and what is its capacity?
Yes, the PIC16LF18877-I/PT integrates 256 bytes of on-chip EEPROM data memory that retains stored values through power cycles without an external serial EEPROM. This is sufficient for storing calibration constants, configuration settings, and event counters in industrial sensor and appliance control applications.
For an analog sensor interface, how do the ADC and DAC on the PIC16LF18877-I/PT reduce external component count?
The PIC16LF18877-I/PT includes a 10-bit ADC with computation (ADC2) for direct sensor digitization and an on-chip DAC for reference or analog output generation, removing the need for external ADC and DAC ICs. Combined with the 1.8V to 3.6V supply range, this enables a complete single-chip analog signal chain for sensors requiring excitation and measurement within the same device.
