Frequently Asked Questions
How much non-volatile storage does PIC16F87-I/ML provide for firmware and user data retention?
The PIC16F87-I/ML offers 7 KB of Flash program memory for firmware storage and 256 B of EEPROM for retaining calibration constants and configuration data across power cycles. The 368 B of RAM supports runtime variable storage during code execution at up to 20 MHz, providing sufficient memory for most simple embedded control tasks without external storage devices.
What clock frequency does PIC16F87-I/ML support and how does this affect real-time control responsiveness?
The PIC16F87-I/ML operates at a maximum clock frequency of 20 MHz, executing one instruction per 4 clock cycles, which translates to 5 million instructions per second. This throughput is sufficient for real-time control loops in motor drivers and sensor interfaces with response times down to 1 µs, while consuming modest supply current in the low-milliamp range at full speed.
Does PIC16F87-I/ML include an on-chip ADC and what alternatives exist when analog sensing is needed?
The PIC16F87-I/ML does not include an on-chip ADC, which means analog sensor signals must be digitized externally using a separate SPI or I2C ADC before being processed by the 8-bit PIC16 core. For applications requiring 10-bit or 12-bit analog-to-digital conversion, designers may consider the PIC16F88 variant which integrates an 8-channel 10-bit ADC in a pin-compatible 28-pin package.
What PCB footprint does PIC16F87-I/ML occupy and how does it compare to DIP alternatives for prototyping?
The PIC16F87-I/ML is housed in a 28-pin VQFN surface-mount package with a body size of approximately 4 mm x 4 mm, roughly 10 times smaller in area than the equivalent 28-pin DIP through-hole package. While this compact QFN footprint is excellent for production PCBs, prototyping requires a QFN adapter board; the PDIP package variant of PIC16F87 is the preferred choice for breadboard development during early design phases.
