FAQ

What is the maximum operating frequency and core architecture of the PIC16F15345T-I/SS?

The PIC16F15345T-I/SS features an 8-bit RISC core with a maximum clock input of 32 MHz and a 125 ns minimum instruction cycle. It executes only 49 instructions, optimized for C compiler efficiency and deterministic real-time control. This architecture enables precise timing-critical tasks such as motor commutation and sensor sampling without jitter.

Does the PIC16F15345T-I/SS support hardware debugging, and what interface is used?

Yes, the PIC16F15345T-I/SS supports in-circuit debugging via the two-pin ICSP™ interface using RA0/ICSPDAT and RA1/ICSPCLK. Debug functionality is integrated on-chip (class I), enabling full breakpoint, step-through, and register inspection capabilities without requiring additional debug hardware beyond a standard PIC programmer/debugger tool.

What analog peripherals are integrated into the PIC16F15345T-I/SS, and how many channels do they support?

The PIC16F15345T-I/SS integrates a 10-bit ADC with up to 17 external input channels, two comparators with selectable reference voltages (1.024 V, 2.048 V, 4.096 V), and a 5-bit rail-to-rail DAC. These analog resources are accessible across multiple pins and support concurrent operation - for example, ADC conversions can occur during Sleep mode while comparators monitor thresholds autonomously.

How does the Peripheral Pin Select (PPS) feature benefit PCB design for the PIC16F15345T-I/SS?

The Peripheral Pin Select (PPS) feature allows full remapping of digital peripheral outputs (EUSART, SPI, I²C, CCP, CWG) and inputs (EUSART RX, CCP capture, CLC inputs) to any general-purpose I/O pin. This eliminates routing bottlenecks in dense layouts, enables reuse of existing board designs across variants, and simplifies compliance with signal integrity requirements by allowing optimal pin placement for high-speed or noise-sensitive signals.

What power-saving modes are available on the PIC16F15345T-I/SS, and what is the lowest achievable current draw?

The PIC16F15345T-I/SS offers Doze, Idle, and Sleep modes, with Sleep mode drawing just 50 nA typical at 1.8 V. Additional low-power features include Peripheral Module Disable (PMD) to shut down unused peripherals, Low-Power BOR (LPBOR), and configurable Watchdog Timer (500 nA typical). These capabilities make it ideal for energy-harvesting and battery-operated edge devices requiring multi-year operational life.
